A method and device for monitoring soil and water loss in a cave system

Abstract

The invention provides a cave system type water and soil loss monitoring method and an apparatus thereof. The method comprises the following steps: carrying out tracing researches to determine a superimposed soil point position corresponding to a cave water and soil loss point; collecting the superimposed soil point corresponding to the cave water and soil loss point; monitoring the water and soil loss of the cave water and soil loss point, and sampling the cave water and soil loss point; carrying out experiment analysis on a collected water sample and a collecting soil sample; and analyzing and processing obtained data to obtain a conclusion. Important references are provided for researching the underground water and soil loss of rocky desert areas and systemically researching the water and soil loss of the earth's surface in order to provide scientific basis for monitoring and evaluating rocky desert environment and assessing treatment benefits. The method and the apparatus belong to the field of rocky desert environment researches.

Description

technical field [0001] The invention relates to a monitoring device and method, belonging to the field of rocky desertification environment research. Background technique [0002] As the primary problem restricting the sustainable development of Southwest my country, karst rocky desertification has always been concerned. With the gradual advancement of rocky desertification control work, its environmental monitoring and effectiveness evaluation have become important reference points in the control plan. How to accurately and effectively monitor and evaluate its control effect is a key issue that needs urgent attention. [0003] Water and soil loss is a key part of the rocky desertification process, including surface and underground loss. Many traditional research methods are too limited to the surface environment, and there are relatively few studies on underground loss, lacking the basis provided by binary geological structure monitoring. The dual monitoring of the surface...

AI Technical Summary

Problems solved by technology

However, in areas where rocky desertification is more serious, due to the impact of soil erosion, the slope of the mountain is relatively large, the soil is barren, and due to the impact of karstification and weathering, stone buds and karst ditches are relatively developed.

Therefore, this geomorphic feature has caused great difficulties in soil water collection, and traditional soil water collection methods are not suitable for areas with severe rocky desertification

[0005] In addition, because the surface soil in the karst rocky desertification area is relatively poor and the bedrock exposure rate is high, karst and weathering cause more bedrock fissures, which affects the development of cave fissures, and the surface soil (mainly clay) will be filtered with precipitation Carried to the inside of the cave, causing surface water and soil to leak into the underground cave
