Abstract
Soil erosion is one
of the most serious ecologic and environmental issues in the Upper Reaches of
the Yangtze River,
As a kind of
natural process, soil erosion is certainly inevitable, whereas the state of
erosion expanding, spreading and worsen rapidly is a result of activities of
the mankind. The research shows that soil erosion mainly came from slope-land cultivation
in this region, which is accounting for about 60% of the total erosion quantity. So, More
attention should be paid on the research of mechanism of the human system,
especially of mountain poverty. In this paper, based on field survey data and
statistical data, a model has been built to illustrate mechanism of soil erosion
on human dimension.
Keywords: Soil erosion; poverty;
mechanism; the Upper Reaches of Yangtze River
