Side slope soil erosion modulus measurement method for waste dump of mine

Abstract

The invention relates to a slide slope soil erosion modulus measurement method for a waste dump of mine. The method is characterized by comprising the following steps: firstly measuring an erosion surface area of a to-be-measured side slope; constructing a measurement groove at the lower side of. The to-be-measured side slope, laying a thin film in the inner surface of the groove to reserve the side slope loss soil; collecting the loss soil at fixe time, and measuring the loss soil weight; and finally computing the soil erosion modulus by using the measured erosion surface area and the loss soil weight. A large amount of unnecessary monitoring loops and computation processes are reduced, and the method is suitable for the small-range side slope soil erosion modulus measurement under the stranger environment. The method has the characteristics of being simple in process, easy to implement, extensive in raw material source, cheap in price, low in cost, fast and accurate, and can be promoted and applied to the measurement of other varieties of side slope soil modulus.

Description

technical field [0001] The invention relates to the fields of soil and water conservation and restoration ecology, in particular to a method for measuring the soil erosion modulus of slopes in mine dumps. Background technique [0002] The soil erosion modulus is the unit of soil erosion intensity and a quantitative index to measure the degree of soil erosion. Also known as soil erosion rate, soil loss rate, or magnitude of soil loss. It refers to the amount of soil erosion that is denuded and displaced per unit area and unit time under the combined effects of natural forces (hydraulic, wind, gravity, freeze-thaw, etc.) and human activities. [0003] China is one of the countries with the most severe soil erosion in the world. Due to the special physical geography and socio-economic conditions, soil erosion has become a major environmental problem. Water and soil loss in my country has a wide distribution and a large area. According to the published results of the second re...

The patent application number is 201710406264.0 "An Improved K#RUSLE Model and Method for Calculating Soil Erosion by Soil Formation Rate", which karstizes the rainfall erosive force factor, and effectively calculates the theoretical soil erosion modulus based on the threshold value of soil formation rate It improves the accuracy of soil erosion results, but it is still based on the RUSLE model, which requires long-term monitoring and calculation. Although the accuracy is high, it takes a long time, the operation is difficult, and the workload is heavy.
