Research Progress of Spatial Distribution about Geomorphologyl-Vegetation- Water Erosion Based on Remote Sensing in Soil Covered Pisha Stone Area

Abstract

Abstract The soil covered Pisha stone area is the core source area of the coarse sediment in the Yellow River, it has become the focal point of the ecological control of the Yellow River Basin. It has important value to study the spatial distribution about geomorphologyl-vegetation- water Erosion coupling in the soil covered Pisha stone area. Some valuable research results have been obtained by using high-definition remote sensing aerial photographs and unmanned aerial vehicle high precision data interpretation, Especially the image resolution obtained by unmanned remote sensing to obtain the spatial structure features of small watershed topographic features or vegetation structure characteristics. Use remote sensing to study the spatial distribution characteristics of soil erosion in the Pisha stone area slope and the regular response with time change on the geomorphic spatial structure of the slope is very important, the negative response relation between the spatial structure of the vegetation community and the energy dissipation impedance erosion need be study. It will be an urgent scientific problem to promote the research progress of soil erosion in pisha stone area, which will directly affect the theoretical foundation of the comprehensive treatment model of soil erosion in Pisha stone area.
