Soil erosion is one of the widespread crises in China.The problem has caused water and soil resource destruction,eco-environment degradation and so on.Moreover,soil erosion is one of the main reasons for regional poverty.By statistical approaches,this paper presents that there is a kind of coupling relationship between the region of soil erosion and the distribution of poverty population.The relationship is characterized by the following aspects.First,eco-environmental degradation can induce soil erosion.Second,soil erosion is the fountainhead of eco-environmental degradation and poverty by restricting the significant use for limited resources and increasing environmental pressures.Third,further poverty can also accelerate soil erosion and eco-environmental degradation.Under such considerations,it is necessary to pay more attention to soil and water conservation projects in order to realize the sustainable resources utilization of water and soil.If so,the eco-environment can be improved,the people's income can be increased and the poverty will be alleviated step by step.
