摘要
用索伯网(Surber)定量采样法,在河南省沙河上游水系1、2、3和4级支流的18个样点采集108个样方,总面积27m2,共获水生昆虫9目78科95属种4842只,并分别利用香农-威纳多样性指数和科级水平生物指数法对沙河上游水质进行了评价。
Shahe River is the Huaihe River＇s important branch. Benthic macroinvertebrates were sampled at 18 sampling sites in the upper reaches of Shahe River. A total of 4 842 individuals were collected including 108 genera,and the benthic macroinvertebrate density of every site was 74.00-555.33 /m2. Water quality of 18 sites were evaluated by the Shannon-Weiner index and the Family-Level biotic index.
