摘要
Abstract
To summarize the impact of different water level operations on the phytoplankton community structure in Miyun Reservoir,phytoplankton measurements have been conducted since 2005,including qualitative and quantitative assessments.Based on years of monitoring data,the community diversity,richness,and evenness were calculated and analyzed using R language to study the succession patterns of the phytoplankton community composition during different water level operations.Additionally,the distribution trends of the phytoplankton community in Miyun Reservoir were analyzed.The results indi-cated that the South-to-North Water Diversion into Miyun Reservoir significantly impacted the struc-ture of phytoplankton in the water body.Specifically,the filamentous blue-green algae Pseudanabaena becoming the dominant blue-green algae species.The operation at high water levels transformed the res-ervoir area from a blue-green algae-dominated water body to a diatom-dominated one.This research provides technical references for maintaining the water conservation functions of Miyun Reservoir.关键词
