摘要
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。
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 ecoenvironmental 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.
