摘  要:
于2007年8月至2008年5月,对筼筜湖外湖深水区(YD-Ⅰ)、内湖(YD-Ⅱ)及干渠浅水区(YD-Ⅲ)3个调查站位进行冬、春、夏、秋4个生物季节的大型底栖生物调查,调查共鉴定大型底栖生物(Macrobenthos)9种,隶属于3门3纲8科9属。其中多毛类种数最多,达5种,双壳类软体动物2种及端足类甲壳动物2种。小头虫(Capitella capitata Fabricius)和腺带刺沙蚕(Neaethes glandicincta Southern)2种多毛类是筼筜湖底栖生物群落的优势种群。筼筜湖年总生物量为59.83g/m2,总栖息密度为1168个/m2。三个站位四季总体上内湖(YD-Ⅱ)的多样性指数(H′),均匀度指数(J)丰富度指数(d)和优势度指数(D2)相对较高,外湖(YD-Ⅰ)及干渠浅水区(YD-Ⅲ)的各项生态特征指数明显较低,筼筜湖底栖生物群落组成、结构、时空变化与环境密切相关,湖区生境脆弱。

摘  要:
Three stations were established to investigate the macrobenthos in Yuandang Lake in Xiamen during the period of August 2007 and May 2008.Three stations were deep water district of lake(YD-Ⅰ),interior lake(YD-Ⅱ)and shallow water of district of trunk(YD-Ⅲ).A total of 9 species were identified in the macrobenthos,which belong to 3 phyla,3 classes,8 families and 9 genera,among which there were 5 species of Polychaeta,2 species of Mollusca,and 2 species of Amphipoda.Capitella capitata(Fabricius) and Neaethes glandicincta(Southern) are the dominant species in benthic community.The total biomass is 59.83g/m2,and the total inhabited density is 1168ind./m2.Shannon-Wiener information index diversity(H'),Pielou's evenness index(J),Margalef's species richness index(d),and Simpson's dominance index(D2) of species in YD-Ⅱwere higher than other stations.Benthic community composition,structure,and spatio-temporal variation closely related to the environment in Yuandang Lake.The ecological environment of Yuandang Lake is frangible.
