1 基本情况内乡县境内属丹江口水库水源区的面积有3.77万hm~2,其中水土流失面积2.45万hm~2。严重的水土流失,使大量泥沙进入水库造成淤积。为保证南水北调中线工程的供水质量,响应水利部“加强封育保护,充分发挥生态自我修复能力,加快治理水土流失步伐”的号召,内乡县水源区的水土保持生态修复工作取得了实质性的进展。截至目前,水源区共实施封育保护8614hm~2,对封育区内的6030hm~2疏林进行了补植补造,改造建设基本农田1600hm~2,完成退耕还林和荒山绿化3000hm~2,实行保土耕作3900hm~2。这些措施的实施,有效减缓了水土流失,取
1 Basic Conditions The area within Danxiangkou Reservoir in Neixiang County is 37,700 hm ~ 2, of which the soil erosion area is 24,500 hm ~ 2. Serious soil erosion, so that a large amount of sediment into the reservoir siltation. In order to ensure the quality of water supply for the midline project of South-to-North Water Diversion, in response to the call of the Ministry of Water Resources to “enhance the protection of enclosures, give full play to the ability of ecological self-restoration and accelerate the pace of soil and water loss control”, the ecological restoration of soil and water conservation in the water source area of Neixiang County has been made substantive Sexual progress. Up to now, a total of 8,614 ha ~ 2 of enclosure and protection has been implemented in the water source area, and 6,030 ha ~ 2 sparse forests in the enclosed area have been replanted and rebuilt to construct 1600 mu ~ 2 of basic farmland, , The implementation of tillage farming 3900hm ~ 2. The implementation of these measures has effectively slowed soil erosion
