摘　　要：宁武县汾河流域水土流失面积为1186 km^(2),主要分布有土石山和黄土丘陵沟壑区侵蚀地貌。绝大部分降雨产生的径流,以山洪倾泻于河道,形成了境内水资源时空分布高度集中、地下水和地面水高度集中的特点。根据宁武县地形、地貌、行政区划、土地利用现状、生态环境敏感性、生态系统服务功能等,将宁武县划分为九个生态功能区,提出了相应的治理保护措施。The area of soil erosion in Fenhe River Basin of ningwu county is 1186 km^(2),and there are mainly erosion landforms in earth-rock mountains and loess hilly and gully areas.Most of the runoff generated by rainfall is poured into the river by mountain torrents,which has formed the characteristics of high concentration of water resources in time and space,and high concentration of groundwater and surface water.According to ningwu county’s topography,landforms,administrative divisions,land use status,eco-environmental sensitivity,and ecosystem service functions,ningwu county is divided into nine eco-functional zones,and corresponding control and protection measures are put forward.
