微山湖人工鱼礁区建设后水质状况变化特征OA

At present,current research on artificial reefs predominantly focuses on marine environments,with a nota-ble lack of studies addressing the construction of artificial reefs in freshwater lakes.This study takes the artificial reef area of Weishan Lake as the research object,investigating its water quality during the months of October and Decem-ber in 2021 as well as July,August and September in 2022.The environmental single factor index method and com-prehensive nutrition index method are employed to evaluate the water environment quality comprehensively,and the differences between the artificial reef area and the control area with different materials are compared and analyzed as well.To evaluate the effectiveness of fishery environmental protection following the deployment of the artificial reef.The results indicate that the water quality of the artificial reefs made from different materials reached class III water standard and exhibited a mild eutrophic state,while the water environmental quality of the control areas exceeded class IV water standard and displayed a moderate eutrophic state.This indicates that the water quality and comprehen-sive nutritional state of the plastic and cement artificial reefs improved to a certain extent after the artificial reefs im-plementation.The construction of an artificial fish reef area in Weishan Lake holds significant positive implications for the restoration of fish habitats.[Chinese Fishery Quality and Standards,2025,15(5):11-18]
