  The control unit 22 controls the overall operation of the computer 21 according to the program stored in the storage unit 23. The storage unit 23 captures a plurality of types of environmental data such as topographic data and vegetation data in the evaluation target area via the communication unit 24 in order to perform an operation such as an evaluation process of an environmental element such as a green coverage ratio described later. A working area 231 is provided for storage. As this environmental data, for example, map data such as existing vegetation distribution maps, topographic distribution maps, and green cover distribution maps in a GIS (Geographic Information System) data source provided by the Geographical Survey Institute of the Ministry of Land, Infrastructure, Transport and Tourism is used.

  The operation unit 25 is constituted by a keyboard, and is used for inputting various data and operating instructions of the apparatus. The display unit 26 includes a display and is used for displaying various information and data.

  As shown in FIG. 1, an output unit 27 is connected to the control unit 22 of the computer 21. The output unit 27 is configured by a printer, and is used when printing out processing result data or the like.

  The control unit 22 recognizes a plurality of types of environmental elements from the environmental data of the environment development site captured in the working area 231 of the storage unit 23, and the environmental elements are shown in FIG. 11 according to a predetermined standard. The evaluation part which evaluates to is comprised. FIG. 11 shows an example in which the evaluation result is visualized by a radar chart. In this case, as shown in FIGS. 3 to 10, the evaluation target area 31 is set to an area within a predetermined radius 33 from the center of the environment development site 32 that is the development planned site. In this embodiment, the predetermined radius is set to 2 km from an ecological and landscape viewpoint.

  Moreover, the environmental element in this embodiment is comprised by the adjoining of the multiple types of vegetation form of a plant, the multiple types of water area form, and a different environmental form. As the vegetation forms of a plurality of types of plants, the green coverage ratio shown in FIG. 3, the accessibility of the forest area shown in FIGS. 4 (a) and 4 (b), the base property of the forest area shown in FIGS. 5 (a) and 5 (b), and The historical nature of the forest area shown in Fig. 6 is used. As the plural types of water areas, the open water area ratio shown in FIG. 7, the length of the flowing water area shown in FIG. 8, and the accessibility of the water stop areas shown in FIGS. 9 (a) and 9 (b) are used.

As shown in FIG. 12, the control unit 22 constitutes a pattern setting unit for patterning the environmental characteristics of the evaluation target area 31 by ranking the evaluated environmental elements.
The control unit 22 constitutes an extraction unit that compares the pattern of the evaluation target area 31 with the pattern of the reference site stored in the storage unit 23 and extracts the reference site of the same pattern as the evaluation target area 31. And the control part 22 selects the indicator organism which adapts to the environmental characteristic of the extracted reference site, and makes the output part 27 output the data of the ecological environment suitable for the habitat of the indicator organism. That is, the storage unit 23 indicates reference site data indicating a plurality of types of reference sites for each pattern of environmental characteristics as shown in FIG. 13, and indicates the types of indicator organisms adapted to the reference sites as shown in FIG. As shown in FIG. 15, the image data that stores the ecological environment of the site suitable for the inhabiting of the indicator organism is stored. In this embodiment, the indicator organism is an animal such as a dragonfly or a bird. The selection of the indicator organism that adapts to the environmental characteristics of the reference site may be performed manually.

Next, the operation of the ecological environment formulation apparatus configured as described above and the ecological environment design method will be described.
In this ecological environment development device, the operation of each step (hereinafter simply referred to as “S”) in the flowchart of FIG. 2 is sequentially executed according to the program stored in the storage unit 23 under the control of the control unit 22.

  That is, in S1, a plurality of types of map data such as existing vegetation distribution map, topographic distribution map, and green cover distribution map in the GIS data source in the evaluation target area 31 including the planned development site such as a building construction site. Are taken into the working area 231 of the storage unit 23 via the communication unit 24 and are integrated to set map data as environmental data.

  In the subsequent S2, the map data of the development planned place is deleted from the map data of the evaluation target area 31 taken into the working area 231. Accordingly, the environment development site 32 that is the development planned site is excluded from the evaluation target area 31. Next, the green coverage ratio as an environmental element is calculated from the map data set in the working area 231. For example, according to the color legend indicating the green cover in the map data, the green cover ratio is calculated by extracting a layer for the color representing the green cover from the map data and calculating the green cover color in the layer. This is done by counting the number of cells. Therefore, as shown in FIG. 3, the green cover ratio represents the area ratio of the green cover made up of a forest area, grassland, farmland, and the like in the evaluation target area 31. This green coverage ratio is calculated by the following equation (1).

Total area of forest area, grassland and farmland in the area to be evaluated ÷ area of the area to be evaluated (1)
In the next S3, the accessibility of the forest area as an environmental element is calculated from the map data of the working area 231. As shown in FIG. 4, the accessibility of the forest area is how close the forest patches (aggregation area of the forest) distributed in the evaluation target area 31 are to each other from the viewpoint of ease of movement of the indicator organism. Indicates whether or not In other words, it is important that the forest area is close within the distance that organisms can move. And the accessibility of this forest area is calculated as follows.

  First, as described above, in a color layer representing a green cover in a green cover distribution map, a predetermined number (predetermined) of green cell areas that are gathered is identified, and this is a forest patch. And Then, among each forest patch, a specific forest patch is selected as a base point. This selection may be performed manually or may be performed by a predetermined algorithm program. Then, for example, as shown in FIG. 4 (a), the forest patch as the base point is x, and another forest patch within a first search area 35 having a constant first search radius 34 (for example, 200 m) from the base forest patch x. When the area of the forest patch (number of green-colored cells) is A to D and the shortest distance from the base forest patch x to another forest patch is a to d, the accessibility index of the base forest patch x Is calculated by the following equation (2).

A / (a × a) + B / (b × b) + C / (c × c) + D / (d × d) (2)
Furthermore, for example, as shown in FIG. 4B, when the proximity index of each forest patch is set to x1 to x6, the evaluation value of the accessibility of the forest area in the evaluation target area 31 is (3) Calculated by the formula.

Number of (x1 + x2 + x3 + x4 + x5 + x6) / x (3)
In this case, the proximity evaluation value increases as the distance from the forest patch serving as the base point to other forest patches is closer and the area of the forest patch is larger.

  Subsequently, in S4, the base property of the forest area as an environmental element is calculated from the map data of the working area 231. The base property of the forest area represents the ease of inhabiting for the indicator organism in the forest area, that is, the appropriateness as the base of the habitat environment. In general, the larger the forest area, the easier to accommodate indicator species of many types and numbers. In this case, first, as shown in FIG. 5A, the area of the core of the forest patch that is a predetermined distance 36 (for example, 15 m) or more inward from the outer periphery of each forest patch is obtained. And as shown in FIG.5 (b), when the core area of each forest patch is made into AE like FIG. 5, for example, the evaluation value of the base property of the forest area in the evaluation object area 31 is the following Calculated by equation (4).

(A + B + C + D + E) / Area of evaluation target area (4)
Next, in S5, the historicity of the forest area as an environmental element is calculated from the map data of the working area 231. As shown in FIG. 6, the historicity of this forest area represents the area ratio of historical forest areas such as shrines and forests and gardens in the evaluation target area 31. In this case, forest areas such as shrines and temples and historical gardens are considered to have a high degree of naturalness due to the potential natural vegetation in the region or the development of biological hierarchies that show ecosystems. In many cases. For this reason, the historicity of forest areas is important in the ecology of indicator organisms as a mature green element in cities. The historicity of this forest area is calculated by the following equation (5).

Total area of shrines and temples and gardens in the area subject to evaluation ÷ Area of the area subject to evaluation (5)
Here, in the above formula (5), shrines and temples and garden forests showing historical properties may be extracted according to the legend of the map data layer, or a predetermined code representing historical properties may be extracted. You may input manually for every forest area, and you may designate the forest area with the history.

  Furthermore, in S6, the open water area ratio as an environmental element is calculated from the map data of the working area 231. As shown in FIG. 7, the open water area ratio represents an area ratio of an open water surface such as a river, a lake, a pond, a pool, or the sea occupied in the evaluation target area 31. This open water surface is executed by extracting a color layer representing the open water surface according to the color legend indicating the open water surface in the map data and counting the number of cells of the open water color in the layer. And this open water area rate is computed by the following (6) Formula.

Total area of water areas such as watershed, still water, and sea within the area subject to evaluation ÷ area of the area subject to evaluation (6)
In continuing S7, the length of the flowing water area (river) as an environmental element is calculated from the map data of the working area 231. As shown in FIG. 8, the length of the watershed represents the total length of the river in the evaluation target area 31. For this length calculation, for example, a method is adopted in which map data is converted into polygon data, polygons located in the center of the watershed are extracted, and the lengths of lines passing through the center points of these polygons are calculated. . And the evaluation value of the length of this watershed is calculated by the following (7) formula, when the channel length which makes a boundary the junction of a river is made into x1-x5 like FIG. 8, for example. The

(X1 + x2 + x3 + x4 + x5) / area of the area to be evaluated (7)
In the next S8, the accessibility of a water stop area such as a pond or a marsh as an environmental element is calculated from the map data of the working area 231. As shown in FIG. 9, the accessibility of the water stop area represents ease of movement between water stop area patches of flying creatures or the like that use the water stop area in the evaluation target area 31. For example, for flying creatures such as dragonflies, it is important that other waterstops exist within a distance that can fly from a certain waterstop. Then, the accessibility of the still water area is calculated as follows, almost the same as the proximity of the forest area in S3.

  First, for example, as shown in FIG. 9A, the water stop area patch as a base point is x, and within the second search area 38 having a constant second search radius 37 (for example, 3 km) from the water stop area patch x of the base point. When the area of another water-stop patch is A to D, and the shortest distance from the water-stop patch x to another water-stop patch is a to d, the accessibility index of the water-stop patch x is the following (8). The selection of the water stop zone patch x as a base point may be performed manually or by a predetermined algorithm program.

A / (a × a) + B / (b × b) + C / (c × c) + D / (d × d) (8)
Further, for example, as shown in FIG. 9B, when the proximity index of each water stop area patch is set to x1 to x5, the evaluation value of the water stop area accessibility in the evaluation target area 31 is (9 ).

Number of (x1 + x2 + x3 + x4 + x5) / x (9)
Subsequently, in S9, the adjacency of different environmental forms as the environmental element is calculated from the map data of the working area 231. The adjacency of the different environmental forms represents the richness of the boundary regions of the different environmental forms in the evaluation target area 31, as shown in FIG. For example, six types of boundary areas, ie, a forest area and grassland, a forest area and farmland, a forest area and water area, a grassland and farmland, a grassland and water area, and a farmland and water area, are evaluated. For example, the boundaries between forest areas and grassland are called ecotones (transition zones) and play an important role in increasing environmental diversity. And the adjacency of this different environmental form is calculated by the following (10) Formula.

Total area of boundary areas of different environmental forms within the evaluation target area ÷ Area of the evaluation target area (10)
In this case, the area calculation of the boundary regions of different environmental forms is performed as follows using the neighborhood statistical function. That is, as shown in FIG. 10B, the data of the forest area, grassland, farmland, and water area of the green cover distribution map is represented by a cell of a predetermined size (for example, 5.6 m), and attribute information can be stored. In addition, the data is converted into a raster data format that can be numerically analyzed. For example, when a boundary region between a forest area and a grassland is extracted, all “1” are given to the cells in the forest area and “0” is given to all the cells in the grassland. In this state, circles 39, 391, 392... For a radius of 3 meshes are generated from all meshes as base points, and the sum of “1” and “0” in the circles 39, 391, 392. The average value of is calculated. In this case, a mesh in which the center of the mesh is included in the circles 39, 391, 392.

  Here, the average value of “9 ÷ 21 = 0.43” in the circle 39, the average value of “20 ÷ 21 = 0.95” in the circle 391, and “2 ÷ 21 = 0.1” in the circle 392. Is output as an attribute of the mesh at the center of each of the circles 39, 391, and 392. This average value is high in places with a lot of forest areas, low in places with a lot of grassland, and is an intermediate value in places where the forest areas and grasslands are included in the same area. From this, cells having an average value of “0.4 to 0.6” are extracted as boundary regions, and the area of the boundary region is calculated by counting the number of extracted cells.

  Next, in S10, each of the eight environmental elements calculated in S2 to S9 is evaluated. In this case, in the entire area including the evaluation target area 31 such as the city, the evaluation values for each of the eight environmental elements are preliminarily calculated. The maximum value in the entire area is “1”, the minimum value is “0”, and the median value is The evaluation reference value is defined as “0.5” and stored in the storage unit 23. And the data of each environmental element calculated by said S2-S9 are evaluated according to the evaluation reference value prescribed | regulated previously, and as shown to Fig.12 (a), the evaluation value of each environmental element is "1-0". Expressed as a relative value between.

  Subsequently, in S11, as shown in FIG. 11, the evaluation value of each environmental element is charted on a regular octagon radar chart and displayed on the display unit 26, and from the output unit 27 as necessary. Is output. With this radar chart, the evaluation result of the evaluation target area can be confirmed at a glance.

  In the next S12, ranking and patterning of the evaluation values of the environmental elements are performed. That is, as shown in FIG. 12 (a), the evaluation values of the environmental elements expressed by relative values are first ranked into three ranks A, B, and C. In this case, the evaluation value is “0.66” or more, A, the evaluation value is “0.33” or more and less than “0.66”, B, and the evaluation value is less than “0.33”, C. Will be ranked as Furthermore, as shown in FIG. 12B, the ranked evaluation values are arranged in the order of environmental elements, and the pattern of environmental characteristics of the evaluation target area 31 is set.

  Next, in S13, a reference site such as an existing park having the same environmental characteristics as the environmental characteristics pattern of the evaluation target area 31 is extracted from the database stored in the storage unit 23 in advance. In this case, the calculation, evaluation, ranking, and ranking of each environmental element are performed for a large number of park green areas with biological information and similar areas in areas such as cities that already include the evaluation target area 31, as in S2 to S12. Patterning has been performed to create a pattern of environmental characteristics. As shown in FIG. 13 and FIG. 14, the environmental property pattern data of a plurality of types of reference sites and the names of the reference sites of each pattern are stored in the database of the storage unit 23. For this reason, from this database, it is possible to search and extract a reference site such as a park having the same environmental characteristics as the environmental characteristics of the evaluation target area 31, in other words, the environmental characteristics around the environment development site 32. . In this case, it is preferable to select a reference site having a size comparable to the area of the evaluation target area 31 for ecological environment formulation.

  In the next S14, as shown in FIG. 14, an indicator organism that is adapted to the environmental characteristics of the reference site is selected from the extracted indicator organism list of insects and wild animals in the reference site such as a park. In this case, the species of the indicator organism is selected from the viewpoint according to necessity, such as the species of the indicator organism typical in the environment of the extracted reference site and the upper species of the ecosystem pyramid.

  In subsequent S15, image data of the site environment suitable for the habitat of the selected indicator organism is output, and the image is displayed on the display unit 26 and printed on the output unit 27. That is, as shown in FIG. 15, the storage unit 23 stores data indicating a landscape of a site suitable for the habitat of the indicator organism. Therefore, a site environment suitable for the inhabiting of the indicator organism can be extracted from the data as an image, and a landscape plan can be performed while referring to the image.
