| 中文摘要: |
| 首次针对香格里拉保护区水生生态系统状况进行调查。河源到河口共设置１６个采样河段，采集到的大型底栖动物共计９目３９科（亚科）６１种（属），划分为３４个不同敏感类群（科或属），并给出不同种类所指示的水质状况。采用香农生物多样性指数（Shannon wiener Diversity Index）和ＭＢＩ生物指标（Macroinvertebrate Biotic Index）对大型底栖无脊椎动物群落进行计算、评价和分类，对岗曲河的水质状况进行快速生物评价。研究表明：除了一些靠近矿山和村庄下游河段，香格里拉保护区水生生态系统生物种类组成丰富、水质状况良好，其调查数据和研究结果是进一步开展保护区水生生态系统研究的基础，也可作为同类型河流生态系统评价的参照。

| 英文摘要: |
| It was the first time to handle an investigation on the aquatic ecosystem of Gangqu River in Shangri-la Gorge ; this investigation expressed its goals in terms of restoring, preserving and sustaining the health and biodiversity of aquatic ecosystems; and according to its unique habitat and community composition, this article also proved that it was significant to carry out further research. The macroinvertebrate assemblages were collected from 16 sampling sits in Gangqu River, including 9 orders, 39 families （sub-families）, 61species （genera）. In addition, 34 maeroinvertebrates were classed according to their sensitivity based on the collection experience, reference data and experts system; different guilds were gave the indication of water quality status. Shannon-Wiener Diversity Index and Macro-invertebrate Biotic Index （MBI） were developed and used to evaluate quantitatively water quality as a rapid bio-assessment. The outcomes indicated that it was special in biodiversity of zoobenthos in Shangri - la conservation area and most reaches of Gangqu River was in good conditions except those near to the villages and mining. It was significance to carry out the further research and conservation of Shangri-la area. |
