生态清洁小流域建设对于维护重要水源区水生态安全具有极其重要的意义。以汉江上游的陕西省石泉县饶峰河小流域为研究对象,在对该小流域自然因素和社会经济因素进行调查的基础上,采用GIS空间分析方法,对该小流域治理区域进行精细划分。研究表明饶峰河小流域可划分7个不同的治理区域,分别为:生态修复区、坡耕地修复区、坡面治理区、坡耕地治理区、农田治理区、村镇综合治理区及河(沟)道周边整治区。根据各区域的污染产生特点,针对性地提出各区域治理方向,并进行治理措施配置。该研究可为生态清洁小流域精准治理提供一种新的建设思路。
Ecological cleanup Small watershed construction is extremely important for the maintenance of water ecological security in important water source areas. Based on the investigation of the natural and socioeconomic factors in the small watershed of Rao Feng River in Shiquan County, Shaanxi Province, upstream of the Han River, GIS spatial analysis method was used to finely divide the governance area of the small watershed. The research shows that Rao Fenghe small watershed can be divided into seven different treatment areas: ecological restoration area, sloping cropland restoration area, slope management area, slope farmland management area, farmland management area, village and town comprehensive management area and river Road regulation area. According to the characteristics of the pollution in each region, it proposes the direction of each region’s governance in a targeted manner and allocates the control measures. This research can provide a new idea for the construction of ecological clean watershed.
