The invention discloses a method and a system for determining a soil and water conservation scheme based on soil and water loss measurement. The method comprises the steps of: obtaining a slope surface condition in a karst area, wherein the slope surface condition in the karst area comprises a slope surface inclination angle in the karst area, a slope surface bedrock exposure rate of the karst area and a slope surface underground porosity in the karst area; determining a soil layer sample according to the slope surface condition in the karst area; performing rainfall on the soil layer sample by using a rainfall experiment, and determining a soil and water loss amount of the soil layer sample; determining water and soil surface loss and underground leakage rules in the karst area accordingto the soil and water loss amount of the soil layer sample; and determining the soil and water conservation scheme in the karst area according to the water and soil surface loss and underground leakage rules in the karst area. By adopting the method and the system for determining the soil and water conservation scheme based on soil and water loss measurement disclosed by the invention, the problemthat the soil and water loss in the karst area can be only measured in the field, thus wasting time and labor in the prior art, is solved.
Description
Technical field [0001] The invention relates to the fields of soil and water and soil conservation and environmental science, and in particular to a method and system for determining a water and soil conservation plan based on water and soil erosion measurement. Background technique [0002] The southwest karst area is located in the core area of East Asia, one of the world's three major karst concentrated areas. It is an important ecological barrier area for the upper reaches of the Yangtze and Pearl Rivers, and is also a key area for national ecological construction. In recent years, the process of soil erosion on slopes in karst areas has become the focus and frontier of the global physical geography community, and has received great attention from many international organizations. [0003] The special surface and underground double-layer spatial structure of the sloping land in the southwest karst area makes the soil erosion process in the karst area unique and complex. Soil ...
