中国水土流失与贫困的关系分析

水土流失是我国目前面临的严重危机之一，所造成的危害不仅表现在水土资源破坏、生态环境退化等方面，而且已成为区域贫困的主要根源。应用统计分析等方法，研究证明了我国水土流失区与贫困人口的空间分布具有地理耦合性。二者相互影响，互为因果，生态的破坏导致了水土流失，水土流失又限制了对有限资源的有效利用，增加了环境的压力，成为生态恶化和贫困的根源，同时进一步的贫困又加速了水土流失和生态恶化。因此，全面推进水土保持，控制水土流失，可以实现水土资源的可持续利用，有效改善生态环境，增加农民收入，逐步从根本上减轻贫困。

Study on Relationship Between Soil Erosion and Poverty

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.
