县河是长江上游汉江的三级支流,治理前有水土流失面积10 660 hm2,侵蚀模数3 200 t/(km2.a)。2007年,县河流域被列为“丹治”项目,治理后流域土壤侵蚀模数低于1 400 t/(km2.a),土地利用率高于98%,林草覆盖率高于85%,各项措施减少土壤侵蚀量70%多,治理期末流域农业总产值、农业人均纯收入等指标较当地平均水平高出30%。主要做法有:强化管理,确保质量;顺应形势,转变思路;培育典型,示范引导;推进改革,创新机制;加强领导,落实责任。
County River is the third tributary of the Hanjiang River in the upper reaches of the Yangtze River. Before the harnessing, there was 10 660 hm2 of soil erosion and an erosion modulus of 3 200 t / (km 2.a). In 2007, the county river basin was classified as “Danzi” project. After the management, the soil erosion modulus was less than 1 400 t / (km2.a), the land utilization rate was higher than 98% and the forest coverage rate was higher than 85 %, All measures to reduce the amount of soil erosion by more than 70%, the end of the management of the basin agricultural output value, per capita net income of agriculture and other indicators higher than the local average of 30%. The main approaches are: strengthening management and ensuring quality; adapting to the situation and changing train of thought; nurturing typical and demonstrative guidance; promoting reform and innovation mechanisms; strengthening leadership and implementing responsibilities.
