摘要
Abstract
The spatial and temporal distribution characteristics of phytoplankton communities in urban artificial lakes and their eutrophication risks will seriously affect their ecological landscape functions.This study conducted cluster analysis(CA)on the phytoplankton community structure and environmental factors of an artificial lake in Fuzhou,dividing it into four regions,and further analyzing the eutrophication status and pollution causes in different regions to propose targeted control strategies.The results showed that the biomass of phytoplankton in region Ⅰ was 0.14 mg·L-1,mainly composed of diatoms.The highest biomass of phytoplankton in Region Ⅱ was 0.22 mg·L-1,with cryptophyta and diatoms dominating.And regions Ⅲ and Ⅳwere river water bodies with low algae content.The TLI index of all four regions are 41.46,42.92,46.08 and 46.83,indicating a moderate nutrient state,while the phytoplankton diversity index showed that regions Ⅰ(2.15)and Ⅱ(1.96)were moderately polluted water bodies,while regions Ⅲ(1.90)and Ⅳ(1.75)were lightly polluted water bodies.The correlation analysis between the structure of phytoplankton communities and environmental factors showed that the environmental factors of phytoplankton communities in the affected areas Ⅰ and Ⅱ were the content of Cu,Pb,and DO in the water body,while the environmental factors of phytoplankton communities in the affected areas Ⅲ and Ⅳ were TN,TP,and NH4+.Based on the pollution characteristics of the four regions,corresponding control and governance strategies were proposed to provide technical support for the ecological management of artificial lakes.关键词
