福建山仔水库春季浮游动物群落分布特征研究
Study on the distribution characteristics of zooplankton communities in spring of Shanzai Reservoir,Fujian Province
摘要
Abstract
[Background]The water quality of drinking water source reservoirs is crucial for residential water supply safety.Zooplankton,as a key component of aquatic food webs,can sensitively indicate ecological changes through shifts in community structure.Human activities such as agricultural cultivation and aquaculture,as well as invasive alien fish species,may significantly impact zooplankton communities,thereby threatening reservoir ecological functions.[Objective]This study aims to reveal the spatiotemporal distribution patterns of the zo-oplankton community in Shanzai Reservoir,a drinking water source in Fuzhou City,Fujian Province,during spring,and to investigate its interactions with phytoplankton and fish communities.[Methods]Water samples were collected from Shanzai Reservoir during spring in May 2023 and May 2024.Zooplankton and phytoplank-ton species were identified,and their densities were analyzed.Concurrently,water quality parameters and envir-onmental factors were measured.[Results]In the spring of 2023,28 zooplankton species were identified,with an average density of(2 932±423)ind·L−1,where rotifers dominated absolutely,accounting for 91.6%of the total density.In the spring of 2024,number of species increased to 33,while density decreased to(1 490±220)ind·L−1,with rotifers still predominant(86.9%).Zooplankton density exhibited a spatial trend of"inlet>reservoir center"in both years(P<0.05).Zooplankton density showed significant positive correlations with dis-solved oxygen(P<0.01)and chlorophyll-a concentrations(P<0.05),and a negative correlation with water trans-parency(P<0.05).Compared with the spring of 2023,zooplankton diversity indices in the spring of 2024 im-proved significantly:the Shannon-Wiener index(H')increased from 1.80 to 2.19,and the Pielou evenness in-dex(J)rose from 0.63 to 0.79,indicating enhanced species distribution equilibrium and optimized community structure.[Conclusion]The spatiotemporal distribution of zooplankton in Shanzai Reservoir is jointly driven by external nutrient inputs and tilapia invasion.The study provides insights for ecological management and eu-trophication control in reservoirs.关键词
