Soil leakage resistance control method for rock-soil contact surface in karst region

Abstract

The invention relates to a soil leakage resistance control method for a rock-soil contact surface in a karst region. The soil leakage resistance control method for the rock-soil contact surface in the karst region includes the steps that plants are planted in soil of the rock-soil contact surface in the karst region, and the plant measure layout is as follows: bare rock of the karst region is taken as the center, and the periphery of the bare rock is divided into four plant measure implementation and layout areas of an upslope position, a downslope position, a left slope position and a right slope position; herbaceous plants are planted in the area close to the bare rock and around the bare rock for a circle; creeping liana plants are planted at the upslope position of the bare rock and close to the outer side of the herbaceous plants; and fast-growing plant hedges are planted on the outer sides, close to the herbaceous plants, of the downslope position, the left slope position and the right slope position of the bare rock, and on the outer sides, close to the liana plants, of the upslope position of the bare rock. The soil leakage resistance control method for the rock-soil contact surface in the karst region is suitable for soil leakage resistance control of the rock-soil contact surface around the bare rock in the karst region, and rocky desertification treatment and water and soil conservation in the southwest rock karst region can be promoted.

Description

technical field [0001] The invention relates to water and soil conservation technology, in particular to a method for controlling soil leakage at the contact surface between exposed rocks and soil in karst areas, which is suitable for preventing and controlling soil and water loss at the contact surface of rocks and soil in karst areas and restoring vegetation in karst rocky desertification areas. Background technique [0002] Rocky desertification in karst areas is very serious, and its water and soil loss is particular, complex and concealed. Karst areas have a double-layer hydrogeological structure on the surface and underground. In addition to surface loss on slopes, water and soil loss also passes through rock-soil contact surfaces or sinkholes. Loss to the underground space, soil leakage is the phenomenon that the soil structure is broken and loosened under the action of external forces such as hydraulic force and gravity, and migrates with the water flow into undergrou...

Problems solved by technology

Engineering measures include building small intercepting ditches with small pieces of stone slurry at the joint between the exposed bedrock and the soil to intercept the runoff on the rock face, block the water flow channel at the rock-soil contact surface, and prevent and control soil leakage. , high cost, land occupation, and poor technical and ecological functions
