康沟流域总面积11664 hm2,水土流失面积11572 hm2,占总面积的99.2%,主要的侵蚀类型是水力侵蚀,以面蚀和沟蚀为主,兼有重力侵蚀等。根据现场调查及统计分析,治理措施根据方案比选确定本流域进行土地利用调整综合治理模式。调整后,农、林、草用地比例将由基期的100∶4.59∶0调整到实施期末的100∶87.05∶5.37,预计通过综合治理,水土流失治理程度由初期的12.94%提高到70.55%,土地利用结构得到合理调整,林草地所占比重由期初的1%提高到19.32%,土地利用率由期初的30.39%提高到72.01%,荒坡封禁,实施生态自我修复。
The total area of the Kangou Catchment Basin is 11,664 hm 2, with an area of 11,572 hm 2 of water and soil loss, accounting for 99.2% of the total area. The main types of erosion are hydraulic erosion, mainly surface erosion and gully erosion, with gravity erosion. According to the field survey and statistical analysis, the governance measures determine the comprehensive utilization of land use regulation in the basin according to the plan comparison and selection. After adjustment, the proportion of farmland, forest and grassland will be adjusted from 100: 4.59: 0 in the base period to 100: 87.05: 5.37 at the end of the implementation period. It is estimated that the degree of soil and water loss control will be increased from 12.94% to 70.55% through comprehensive management. Land use The structure was reasonably adjusted. The proportion of forest and grassland increased from 1% at the beginning of the period to 19.32% and the land utilization rate increased from 30.39% at the beginning of the period to 72.01%. The wasteland was banned and ecological restoration was implemented.
