大黄堡湿地缓冲区池塘浮游植物多样性及水质生态评价
Assessment of plankton biodiversity and aquatic ecology of ponds in the buffer zone of Dahuangpu wetland
摘要
Abstract
[Objective]In order to provide reference for the water environment protection,restoration and rational use of the Dahuangpu wetland ponds,this study investigated the buffer zone ponds of the Dahuangpu wetland phytoplankton community characteristics and the relationship between environmental factors,and evaluated its ecological environment.[Methods]Phyto-plankton samples and water samples were collected from September 15,2021 to October 15,2021 and May 15 to August 30,2022 in the buffer zone pond,to identify phytoplankton species,measure physicochemical indexes,and analysis of the correlation between phytoplankton abundance and environmental factors.[Results]During the monitoring period,a total of 116 species be-longing to 7 phyla were identified,mainly Chlorophyla,accounting for 39.70％of the total.The average abundance of phyto-plankton was 12.63×108 ind./L,and the abundance was dominated by Cyanophyta,accounting for 76.83％of the total.Com-mon dominant species were Oscillatoria sp.,Phormidium sp.,Chlorella sp.and Krichneriella sp..The average values of phyto-plankton diversity index(H'),evenness index(J)and richness index(D)were 1.72,0.36 and 1.39,respectively.The in-vestigated wetland pond water body was at a moderate pollution level.The pH,redox potential,total nitrogen and suspended mat-ter of water body had great influence on the changes of phytoplankton community structure(P＜0.05).[Conclusion]The over-all water quality of the pond in the buffer zone of the Dahuangpu wetland is class V.The phytoplankton is dominated by Cya-nobacterial species and is generally at an extremely eutrophic level.Pollution of this pond with nitrogen and phosphorus com-pounds should be controlled in time to achieve control of Cyanobacteria and avoid the occurrence of algal blooms.关键词
