摘　　要：2006年10月对北京市温榆河12个采样点底栖大型无脊椎动物调查,并设立十三陵水库为对照点。结果表明,温榆河底栖大型无脊椎动物有三大类组成:水栖寡毛类、水生昆虫幼虫和软体动物等13种,水栖寡毛类中的颤蚓科种类和水生昆虫中的羽摇蚊幼虫为优势种,这些均为耐污种类,耐污染指数都在5以上,平均耐污值为8。底栖动物数量也很高,说明温榆河水体受有机污染较为严重。通过1HB指数评价结果,认为对照点水质为一般水体,温榆河为污染水体到严重污染水体。In total 12 samples were collected for the investigations of zoobenthos and macroinvertebrates in Wenyu River in Beijing in October 2006. The comparison sample was collected in Thirteen Tombs Reservoir. The data showed that the zoobenthos and macroinvertebrates in Wenyu River were composed of three genera, which were Aquatic Oligoehaeta, larva of Aquatic Insects and Mollusc. The zoobenthos and maeroinvertebrates could be classified into 13 species. The dominated species were Tubifex in Aquatic Oligochaeta and Cladoeera in Aquatic Insects, which were both pollution-tolerated species and the indexes of pollution-tolerated were more than 5, the mean value was 8. The quantity of zoobenthos was also very large. It showed that the organic pollution was rather serious in Wenyu River. It was considered that the method of Index of 1HB was accurate on the evaluation of water quality. The results by the evaluation of Index of 1HB determined that the water quality of the comparison point was normal and the water qualities of the points in Wenyu River were from polluted to seriously polluted.
