Description

technical field

[0001] The invention relates to a thin-layer slope soil flow measurement system, which belongs to the technical field of hydrology and soil and water conservation, and is used for systematic measurement of hydrological processes, water and nutrient migration in natural and artificial slopes. Background technique

[0002] Thin-layer soil slopes are widely distributed in the upper reaches of the Yangtze River in my country, such as purple soil and yellow soil, both of which are important cultivated land resources. Among them, the purple soil is concentrated in Sichuan Province and Chongqing City (Three Gorges Reservoir Area), and the Sichuan Basin alone covers an area of ​​160,000 km 2 , the yellow soil covers an area of ​​300,000 km in the southwest mountains 2 , purple soil and yellow soil slopes with shallow soil layers (30-90cm), underlying mudstone, shale, and slate with weak water permeability. The distribution area of ​​purple soil and yellow soil has ...
