建国以来,特别是我省的嘉陵江中下游、金沙江下游和三峡库区被列入长江上游水土保持重点防治区后,全省水土保持工作发展较快,累计完成初步综合治理水土流失面积三万多平方公里,治理区的生态环境得到改善,粮食增产,群众经济收入明显提高。但是,严重的水土流失并没有从根本上得到控制,全省水土流失面积二十四点九万平方公里(占全省总土地面积的百分之四十四),年土壤侵蚀总量约十二亿吨,均占长江上游的百分之七十以上。
Since the founding of the People’s Republic of China, especially in the middle and lower reaches of the Jialing River in our province, the lower reaches of the Jinsha River and the reservoir area of the Three Gorges have been listed as the key areas for soil and water conservation in the upper reaches of the Yangtze River, the soil and water conservation work in the province has developed rapidly and the initial comprehensive management of 30,000 Multi-square kilometers, the ecological environment of the administrative area has been improved, grain production, the masses of economic income increased significantly.
