浅论长江三峡库区水土流失现状及治理对策(2)

结语

三峡库区经过10多年的综合治理，治理区内水土保持措施实施情况良好，效益显著。水土流失综合治理使得当地的土地利用结构向着合理的方向转变，坡耕地减少，梯坪地增加，荒山荒坡减少，林地的植被覆盖度提高，有效减少了水土流失，土壤侵蚀强度降低。应该注意的是，人为因素在水土流失中的作用变得越来越突出。特别是三峡库区水土流失治理是事关库区生态环境改善的成败和三峡工程长久安全运行的大事，因此应及早作好库区水保工作和环境保护。

[Abstract] As a result of complexity of topographical and geological conditions, the Three Gorges Reservoir Region is one of the most serous soil erosion land in our country. To some extent, the Three Gorges Dam changes the balanced status of the original geological and geomorphological environment. Though research the Three Gorges Reservoir Region, this paper not only sets forth the current situation as well as harm of the Three Gorges Reservoir Region’s soil erosion, and analyses the forming process of it, but on the basis of them, provides a series of corresponding measures, which make the Three Gorges Reservoir Region greatly control flood and produce benefits, as well as cut down the extent of harm, finally achieve sustainable development.

[Key words] soil erosion; countermeasures; sustainable development; the Three Gorges reservoir area
