摘要
In this paper, as an example for the Yanzi River valley of the Yangtze River basin tributary, selected eight index of area ration of sloping land, Cultivation index, Vegetation coverage, density of agricultural population, agricultural GDP, agricultural per capita income and gully density to indicate the influencing states of soil erosion due to driving force factors, and then, determined connection degree of various indicators by using analysis method of gray system. Finally, according to comprehensive disturbance degree, the paper suggested the soil erosion degree divisions.
