为确保一池清水送北京,河南省在淅川县、西峡县实施了丹江口库区及上游水土保持治理工作,取得了显著成效。一是改善了区域生态环境。项目区生态环境明显改善,水土流失得到有效控制,增加植被面积4万公顷,森林覆盖率由44%提高到76%,年可减少土壤流失量471.65万吨;流域内大量防治体系的布设,增加水源涵蓄能力4390.3万立方米;面源污染得到缓解,年可减少面源污染量6.76万吨。二是切实提高了农业综合生产能力。通过坡改梯、沟建坝、配套小型水利水保工程等的建
In order to ensure a pool of fresh water to Beijing, Henan Province implemented the work of soil and water conservation in Danjiangkou Reservoir Area and Xixia County in Xichuan County, and achieved remarkable results. First, improve the regional ecological environment. The ecological environment in the project area has been significantly improved. Soil erosion has been effectively controlled. The vegetation area has been increased by 40,000 hectares and the forest coverage rate increased from 44% to 76%. The annual soil loss can be reduced to 4,716,500 tons. The layout and control of a large number of prevention and control systems in the basin have increased Water storage capacity of 43.903 million cubic meters; non-point source pollution has been eased, can reduce the non-point source pollution of 67,600 tons. The second is to effectively improve the comprehensive agricultural production capacity. Through slope to ladder, ditch dam construction, supporting small-scale water conservancy and so on
