| Abstract: | The total coverage of land suffered from soil erosion has reached 492 km 2 in China.Apart from the natural factors of soil,precipitation and flora,artificial factors of overgrazing,reclaiming land at side of slopes and constructing projects play a big role.Soil erosion not only destroys the soil resources,but also restrains the agricultural production,pollutes water environment,slits up reservoirs and endangers city safety. |
