Abstract:: Using GIS and relation data,soil erosion change on the Loess Plateau was analyzed in 1986,2000 and 2002.Erosion area rate is 66.13% in 1986,and it raise to 67.14% in 2000,but reduce to 64.88% in 2002.Thereinto,water erosion area exhibited wide trend,wind erosion is reducing,freeze-thaw erosion increased and then decreased from 1986 to 2002.On the Loess Plateau,soil erosion area rate in Inner Mongolia,north of Shaanxi province,Gansu province and Ningxia Hui Aotonomous Region is higher,and is smaller in Qinghai province,middle of Shaanxi province,Hetao plain,Ningxia plain and some areas of Shanxi province.The erosion area rate is 60%~70% from 1986 to 2002,therefore the soil and water erosion is severe as a whole,it is a long way to finish the aim of Green mountain and Clear river.
