| 摘 要： | 2005-03-2005-05对■河杨凌区段的大型底栖动物进行了调查,并以漆水河为参照,应用Trent 生物指数、Chandler记分系统、颤蚓类与全部底栖动物相比的生物指数、Goodnight修正指数和水生昆虫与寡毛类湿重相比的生物指数,同时结合水理化指标对■河水质进行综合分析。结果表明,■河底栖动物共9属．其中环节动物3属,水生昆虫6属;密度和生物量分别为2 728 ind／m2和11.56 g／m2,优势种属为水丝蚓属。■河水体已被污染为超V类水体,且造成漆水河的严重污染。

| Abstract: | The construction of benthos community in the Wei River was investigated from March to May, 2005. To assess the water quality,Trent biotic index,Chandler biotic score,Goodnight biotic index, GBI and King biotic index were applied combining chemical analysis of water. The same work was conducted in Qishui river to be as cross reference. A total of 9 genera of benthos were found,including 3 genera of annelid,6 genera of hydra-insects, The density and biomass of benthos were 2 79,8 ind/m^2 and 11.56 g/m^2 respectively. The dominant genera was Limnodrilus. The results indicated that Wei River has been polluted to Ultra-V level and hence caused heavy pollution to Qishui River. |
