| 摘 要： | 为筛选金沙江上游旭龙江段鱼类栖息地保护支流,从替代适宜性和保护适宜性两个角度构建了鱼类栖息地适宜性评价指标体系,选取了11个与栖息地质量密切相关的评价指标,应用层次分析法确定评价指标的权重值,计算了三条主要支流的栖息地适宜性指数（HSI）,并划分了栖息地适宜性等级。结果表明：重点保护鱼类物种相似性、纵向连通性指数、特有鱼类物种相似性3项指标的权重值位列前三位,分别为0.234、0.234、0.127;定曲、麦曲河、丹达曲的HSI 分别为84.1、72.0和61.3,定曲适宜性等级最高为“高度适宜”,麦曲河、丹达曲适宜性等级为“适宜”。针对当前定曲鱼类生境存在的问题,拟定了补建过鱼设施、开展受损河道生境修复、实施生态调度以及加强水污染监管等对策措施,以期为受水电开发影响下的河流栖息地筛选与保护提供参考。

| Abstract: | In order to screening fish habitat protection tributaries in Xulong section of Jinsha River, 11 evaluation indexes were selected from the aspects of species similarity, habitat similarity, tributary connectivity and ecological health. The weight value of evaluation indexes was determined by analytic hierarchy process, and habitat suitability index (HSI) was calculated by weighted summation. The results show that the weight values of key protected fish similarity, vertical connectivity index and endemic fish species similarity ranked among the top three, which were 0.234, 0.234 and 0.127 respectively; The HSI of Dingqu, Maiqu and Dandaqu are 84.1, 72.0 and 61.3 respectively. The suitability grade of Dingqu is "high suitability", and Maiqu River and Dandaqu is "suitability". Countermeasures such as rebuilting fish passing facilities, restoration of damaged river habitat, implementation of ecological regulation and strengthening of water pollution supervision are proposed, in order to provide reference for fish habitat protection affected by hydropower development. |
