Description
Technical field
The present invention relates to a kind of environment supervision instrument, specifically is the instrument of measured soil erosion groove.
Background technology
The monitoring of the erosion caused by sloping surfaces ditch is the conventional contents of soil erosion microcosmic monitoring, is the basic link of the domatic soil erosion of quantitative examination.Domatic is the most basic geomorphic unit in soil erosion district, and the soil erosion ditches such as rill, dissected valley and coombe on domatic are the basic microtopography forms in water erosion district.Rill erosion occupies critical positions in the soil erosion, research shows, is that main cheuch produces the highest husky 94% of the sediment yield in river basin total amount that accounts for the dissected valley.Be the effectively preventing erosion groove, at first must accurately grasp the development and the change procedure of erosion groove.
Erosion groove is grown in corroding domatic, and general land occupation condition is abominable, and high slope, mountain is steep, and mountain pass is rugged carefully narrow, the carrying up and down of inconvenient large-scale surveying instrument.The sylvan life soil erosion often betides the exposed domatic of tall and big high forest, brings difficulty for airphoto and remote sensing mapping, has limited the development of erosion groove measuring technique.Make a general survey of domestic and international various erosion groove monitoring technology; Can be divided into 2 types of contact and non-contact measurements; Contact measurement method has measurement, chaining pin method (face of land roughness appearance), survey pin method, scale method, chain method etc. manually; At present main space remote sensing and the location technology of relying on of contactless measurement has high-precision GPS, take photo by plane image method and a three-dimensional laser microtopography scanner method.
Measure manually is in monitoring section, to choose appearance ground by a certain percentage; The quantity (bar number) of erosion groove in the appearance ground by inquiry; Measure the key element such as length, the degree of depth, width of every erosion groove, calculate soil erosion amount by the method for approximate shapes (U type or V-type etc.), this method is simple to operate; Technical requirement is not high, but process wastes time and energy, low precision.
The chaining pin method is to measure the height value of ground basic point through many townhouse chaining pins, knows that the landform of microtopography changes.Afterwards through improving " face of land roughness appearance " that forms; Be made up of 51 chaining pins, the length of every chaining pin is 50cm, and the chaining pin spacing is 2cm, when measuring, places examination to survey the district along domatic in this instrument, reads the numerical value of each chaining pin successively." face of land roughness appearance " measuring accuracy, reliability are limited, and the accuracy rating of roughness appearance horizontal direction and vertical direction is the highest can only to reach 2cm and 1cm, and the observation subjectivity is big, seldom use at present.
