摘要
以济南流域为研究区域,分别于2014年5月、8月和11月对济南全流域范围内31个样点的大型底栖动物群落进行跟踪调查,探索济南流域大型底栖动物群落生态分布及时空格局。结果表明,济南流域大型底栖动物类群差异显著;在济南市全年共鉴定大型底栖动物58种,分属9大类,主要优势物种为螺类、水丝蚓和摇蚊;其中5月鉴定的物种数最多,进入8月大型底栖动物物种数明显降低,而11月大型底栖动物物种降低程度逐渐趋于平缓。
In order to study the ecological distribution and spatial-temporal patterns of the macroinvertebrate community of watershed in Jinan,the community structure of macroinvertebrate and characteristics of environmental factors of samples from 31 sites were analysized in May,August and November 2014. The results indicated that there was great difference in the macroinvertebrate community structure in the watershed.There were58 species of macroinvertebrate belonging to 9 categories. The main dominant species of macroinvertebrate are snails,limnodrilus and chironomid.More species were found in May.The numbers of macroinvertebrate species decreased obviously from August and then turn to a slow decreasing in November.
