Description
Technical field
The present invention relates to a kind of instrument of measuring soil erosion ditch and microtopography variation, relate in particular to a kind of portable soil and corrode observation device.
Background technology
The soil erosion is to cause one of key factor of ecological disruption and land deterioration, can bring out the problems such as the deterioration of the ecological environment, aggravation disaster, poverty, so the soil erosion has become the emphasis environmental problem of common concern in the world.China is one of the most serious country of the soil erosion, and national soil erosion area reaches 4,920,000 km
2, account for 51.2% of area; Wherein water erosion area is 1,790,000 km
2, wind erosion area is 1,880,000 km
2, freeze-thaw erosion is 1,250,000 km
2, the environmental problem causing due to the soil erosion is very severe, so monitor accurately China's soil erosion and desertification control in real time significant to the development trend of the erosion caused by sloping surfaces ditch and the microtopography variation of dust storm area.
At present, conventional soil erosion measuring method is mainly divided into two kinds of traditional measurement method and advanced instrument mensurations.Traditional measurement method mainly contains erosion groove district observation method, survey pin method, the method for banketing, amount ditch method etc.; Advanced instrument mensuration mainly contains real time dynamic measurement technology, three-dimensional laser morphologic analysis and the air photo technique etc. of Stable Rare Earth Element Tracer Method, Radionuclide tracer technique, high-precision GPS.Traditional measurement method is widely used in soil erosion monitoring process, and lays conveniently, simple to operate, the common method that wherein monitor on survey pin method development & construction project especially soil erosion ground, and listed water and soil conservation monitoring technology rules in.But traditional soil erosion measuring method also exists many deficiencies simultaneously, as unstablely in the measuring point of laying subject to destroy, lay that workload is large, measuring accuracy is poor, the accuracy rating of measurement data is directly perceived not etc. to dynamics of soil erosion process reaction.Along with scientific-technical progress, advanced instrument increases gradually in the use aspect soil erosion measurement, adopts advanced instrument measuring method, and measuring accuracy is high, real-time, also can save a large amount of manpower and materials simultaneously.But advanced instrument mensuration, in the comparatively complicated location of landform, as hillside fields and the innerland, desert under dense vegetation covering, because instrument carries, is laid difficulty, is difficult to carry out monitoring.For remote sensing image monitoring variable method, due to problems such as lacks of resolution, be difficult to be embodied in the change procedure on micro-scale, be not suitable for carrying out application in monitoring real work.In addition, advanced instrument also exists that cost is high, technology is difficult for grasping, instrument carries the deficiencies such as inconvenience.About trace method, be no matter that its operating process or the preparation of pedotheque, analysis etc. all need to drop into high expense, and research cycle is long, to analysis of experiments, work brings inconvenience.
In sum, for the development trend of the erosion caused by sloping surfaces ditch and the monitoring of dust storm area microtopography variation, that traditional measuring method or advanced instrument measuring method all exists drawback separately, also do not have at present a set of collection easy to carry, lay simple, measuring accuracy higher than the soil erosion observation device of one.
