Abstract: Analysis of the Soil Erosion under the Different Environment Condition鈥斺�攆or Instance in Chongqing CityYANG Cun-jian1,2, ZHANG Zeng-xiang1, WANG Siyuan1(1.Institute of Remote Sensing Applications,The Chinese Academy of Sciences,Beijing100101China)(2.Institute of Ecology and Geobotany,Yunnan University,Kunming650091China)Abstract:In order to discover the relationship between the soil erosion status and its environment factorssuch as temperature, rainfall, vegetation index, topographic index, environment index, the analysis of thesoil erosion under the different environment condition in Chongqing City is discussed here. Firstly, a soilerosion index is defined here to describe the heavy of soil erosion in per unit. Secondly, all of theenvironment data was rasterized into 100M * 100M including topographic index, annual averagetemperature, accumulating temperatures above zero and ten degree, annual rainfall, aridity, humidity, hotindex, water index, hot and water index, environment quality comprehensive index. Thirdly all of theenvironment data were used to overlay with the soil erosion data with grid size of 100 m*100 m. Finally,the statistics analysis function of the GIS is used to discover the relationship between the soil erosion andits environment factors.Key words:Geographic information system, Soil erosion, Environment factors
