摘要
浮游植物的密度和种群组成可以用来评价水体的富营养化状况,是评价水体富营养化的重要参数。但是,目前淮河流域水体富营养化评价较少,缺乏利用河流浮游植物评价河流富营养化程度方面的研究。从2012年12月开始对淮河中上游10个生态监测断面进行现场调查,获取浮游植物种类、密度及水体理化指标数据;利用浮游植物指示生物法、丰度评价法和综合营养状态指数法综合分析水体富营养化状况。结果表明,研究期间硅藻门和绿藻门占据优势地位;各监测断面具有不同的优势物种,且以硅藻门和绿藻门物种为主;总体上沙颍河中下游水体富营养化程度大于沙颍河上游及淮河干流。
The phytoplankton community structure is an important parameter for water eutrophication evaluation,and its density and species composition can be used to evaluate the water eutrophication. However,there is less eutrophication evaluation,and less study on the river eutrophication by phytoplankton in the Huaihe River. December 2012,July 2013,December 2013,and July and December 2014. 5 field experiments are carried out on 10 ecological monitoring sections in the upper and middle reaches of Huaihe River,and phytoplankton species,density and water physicochemical indexes have been got. Eutrophication status are evaluated by phytoplankton indicator biological method,abundance assessment method and comprehensive nutrition state index method. The results show that during the study period,Bacillariophyta and Chlorophyta occupy the dominant position,and the dominant species are different in the different monitoring sections,and Bacillariophyta and Chlorophyta are the dominant species. On the whole,water body eutrophication is greater in the middle and downstream of Shaying River than the monitoring sections of Shaying River upstream and Huai River.
