于2012年枯水期（7月份）和丰水期（9月份），对小鹤立河水库及其上游河流水域浮游植物进行了野外采样调查。经鉴定，调查区域内共有浮游植物145种，隶属8门。从枯水期到丰水期，水库硅藻种类及优势种比例降低，绿藻种类及优势种比例升高，变化较为明显；而河流浮游植物组成及优势种均以硅藻为主，变化幅度较小。从枯水期到丰水期，生物量均降低。通过综合营养状态指数（ TL，I ）分析表明，枯水期到丰水期指数变化不大，小鹤立河流域水质在贫-中营养之间。灰关联分析结果表明，对小鹤立河上游及水库浮游植物丰度影响最大的是水温和透明度。

An experiment was conducted to investigate the phytoplankton structure in Xiaoheli River Reservoir and its upstream rivers from 13 sample stations in dry and rainy seasons ( July and September ) in 2012 .145 species were found belonging to eight divisions.From dry season to rainy season, the ratio of Bacillariophyta and dominant specie is dramatically de-clined, while the ratio of Chlorophyta and dominant specie is markedly raised.There is a slightly change in river, where the community structure of phytoplankton and dominant specie show priority to Bacillariophyta .Biomass and abundance of different sampling sites are reduced.Trophic state index ( TL,I ) demonstrates that all sampling stations are Oligotropher-Mesotropher and the index changes slightly.By grey association analysis, the highest values of grey association degree are water temperature and diaphaneity .
