目前,加速治理长江上游水土流失的必要性,已为许多有识之士所认识.据早期资料估算,长江流域的水土流失面积占流域总面积的20%.水土流失主要发生在山丘地区,四川盆地无疑是上游重点.因此,盆地水土流失的范围和程度如何、怎样加快治理步伐,都是大家非常关心的问题.近年来,有关单位进行了深入的调查研究,基本上弄清了盆地的水土流失情况.

At present, the need to speed up the management of soil erosion in the upper reaches of the Yangtze River has been recognized by many people of insight.On the basis of early data, the area of ​​soil erosion in the Yangtze River Basin accounts for 20% of the total area of ​​the river basin.The soil erosion mainly occurs in the hills, Sichuan Basin is undoubtedly the focus of the upper reaches. Therefore, the extent and extent of soil and water loss in the basin and how to speed up the pace of governance are all issues of great concern. In recent years, the relevant units conducted in-depth investigations and studies and basically clarified the Soil erosion.
