摘　　要：基于GIS空间分析、栅格运算与叠加及RS图像地物提取方法,针对黄河靖南峡-黑山峡河段存在的水土流失、土地沙漠化和土壤盐渍化等生态问题,开展了单因子生态问题敏感性和综合生态敏感性分析.研究表明:中、高度生态敏感区几乎覆盖研究区整个流域,包括景泰县五佛乡、靖远县北湾镇以北和乌兰镇、糜滩乡、东湾镇、三滩乡及平川区的陡城到红柳滩一带;针对高、中和轻度敏感性区域,相应地将研究区规划为禁止开发建设区、中度开发建设区和深度开发建设区.在区域水电开发过程中,应采取积极保护措施,以实现流域生态环境的可持续发展.Abstract： Aiming at the ecological problems such as soil erosion, desertification, and salinization in the Jingnanxia-Heishanxia reach of Yellow River, the single-factorial ecological problem＇ s sensitivity and the comprehensive ecological sensitivity of the reach were analyzed by GIS spatial analysis, grid computing and superposition, and RS image feature extraction. The results showed that the regions with medium- and high ecological sensitivities almost covered the whole study area, including the Wufo Town of Jingtai County, the Beiwan Town, Wulan Town, Mitan Town, Dongwan Town, and Santan Town of Jingyuan County, and the area between Doucheng and Hongliutan of Pingchuan District. The high, medium, and low sensitive areas should be accordingly programmed as forbidden, medium, and deep constructing areas. During the development process of regional hydropower, effective measures should be adopted to protect the ecological environment to achieve the sustainable development of the drainage area.
