Abstract
In order to understand the effect of environmental factors on the distribution of phytoplankton community in different restoration areas of submerged macrophytes after ecological restoration,the environmental factors and phytoplankton community in four different restoration areas of Shangjinhu Lake were investigated successively.The results showed that the concentrations of TN,NH4+-N,TP,DTP and CODMn in the submerged plant restoration area decreased significantly,and the dissolved oxygen(DO)increased significantly(P＜0.05).The phytoplankton in the survey area was dominated by cyanophyta,including pseudanabaena limnetica,microcystis and phormidium,and rotifers were the main zooplankters,among which the trichocerca pusilladegree was the dominant.The algae abundance in submerged plant restoration area decreased significantly.PCoA analysis showed that the community distribution of plankton in different regions was significantly different(P＜0.05).The results of redundancy analysis showed that pH,TN,TP and CODMn were the main environmental factors affecting the distribution of zooplankton community.The results indicated the correlation between phytoplankton community and environmental factors in different ecological restoration areas of Shangjinhu Lake,which could provide data support and decision-making basis for the subsequent water ecological restoration of Shangjinhu Lake.关键词
