摘要
在且末县塔提让乡芦苇湿地沿进水口至出水口的纵轴设置采样点,进行浮游植物多样性指数、丰富度指数以及均匀度指数分析,结果表明,3-1#采样点的多样性指数和丰富度指数最高,各采样点的均匀度指数相差不大.应用典范对应分析(Canonical Correspondence Analysis,CCA)方法对该芦苇湿地中浮游植物及相关理化因子进行分析,结果表明,pH值和溶解氧量(Dissolved Oxygen,DO)是影响芦苇湿地浮游植物群落的重要因子,同时,硝态氮和亚硝态氮含量也是影响其群落结构的重要因素.
The community of phytoplankton in the reed wetland of Tatirang in Qiemo was characterized,the sampling sites were selected from the water inlet to the water outlet,and the Shannon-Weaver,Margalef and Pielou indexes were analyzed.The results indicated that the sampling site 3-1# has the highest Shannon-Weaver index and Species abundance.The Pielou index of each site was not significant.Canonical Correspondence Analysis（CCA）was applied to understand the relationship between the community of phytoplankton and environmental factors.The results showed that the community of phytoplankton was mainly affected by the pH value and the Dissolved Oxygen（DO）,meanwhile,the nitrate and nitrate nitrogen were also an important factor to it.
