摘要
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。
The management of ecological and clean small watershed plays an important role in maintaining water ecological security in key water resource areas.In this paper,spatial analysis was applied to ecological management division of the Raofeng River watershed in Shiquan County,Shaanxi Province based on its nature and social factors.The result of division suggested that Raofeng River watershed can be divided into different ecological management areas including ecological restoration area,sloping cultivated land restoration area,sloping surface treatment area,sloping cultivated land treatment area,farmland treatment area,village comprehensive treatment area and channel treatment area.Also,based on the sources and characteristic of main pollutant of each ecological management areas,the control measures for each area were put forward.These information can provide a new idea for the precise control of ecological and clean small watersheds.
