In this study,  part of the research results of the project “The Remote Sensing Investigation and Monitoring of

the Soil Erosion in Yangtze Valley” was employed as the basis， and the area of middle and lower reaches of the Yangtze

River was chosen as the study area in that this area is characterized by strong economic vitality and fast economical

development. The distribution characteristics of the soil erosion in the middle and lower reaches of the Yangtze River were

analyzed， the unreasonable human activities inducing soil erosion were studied， the original relations between the

correlative geological factors and the soil erosion origin were investigated， and the predominant soil erosion types and

their change tendency were summarized. On such a basis,  some reasonable suggestions concerning soil erosion prevention and

control are put forward.
