Abstract：In order to understand the effects of environment factors on phytoplankton growth， phytoplankton in Dishui Lake had been sampled at 14 monitoring spot locations in December of 2012 and April， July， November of 2013， respectively. The physical and chemical indicators had been monitored to analyze the growth of phytoplankton and the spacetime characteristics of influence factors. Correlative analysis was also made to determine major parameters that influence the growth of phytoplankton in Dishui Lake. It showed that main diversion channel of Dishui Lake is much higher than that of other sites. Seasonal variety of phytoplankton density was similar to that of chlorophylla content， but phytoplankton density of summer was a little higher than that of winter. The effect of filter feeding fish on phytoplankton can explain this phenomenon. Correlation analysis indicated that total phosphorous concentration had great influence on the growth of phytoplankton. This study provides biological basement in evaluating water quality and prevents eutrophication of Dishui Lake.

第2期张艳艳，等：环境因子对滴水湖浮游植物生长的影响分析华东师范大学学报（自然科学版）2015年0引言

作为上海临港新城主城区的中心湖泊，滴水湖承载了新城建设发展的生态资源和环境条件，其水环境的健康与否直接影响到新城区的发展.自建成投入10年以来，滴水湖基本上解决了临港新城主城区的排水出路，也大大提高了防汛排涝能力，然而在水质维护上，由于内源的不稳定和易受外界环境影响等特点，这个于沿海滩涂开挖引水建成的大型人工湖泊出现了与众多人工湖泊极为相似的问题.根据上海市水环境监测中心提供的滴水湖水质状况月报，滴水湖水质近年来维持在Ⅳ—Ⅴ类，主要存在水体透明度略低、水质富营养化程度逐步增加、接近或达到中度富营养化等问题，因此，滴水湖富营养化的防治引起了人们的广泛关注.
