| 摘 要： | 以辽宁省浑河水系为研究范例,调查了全流域范围内62个样点的着生藻类群落和水环境理化特征,并应用着生藻类生物完整性评价指数(P-IBI),结合栖息地环境质量评价指数(QHEI),对浑河流域水生态系统进行健康评价.结果表明:浑河水系着生藻类群落结构具有明显的空间异质性,浑河水系的采样点可划分为4组(Group),不同组间的着生藻类群落结构、物种多度、密度和香农多样性指数均存在明显差异.典范对应分析(CCA)结果显示,驱动浑河着生藻类群落结构形成的水环境因子为铵氮( NH4+-N)和活性磷(PO43--P).P-IBI和QHEI在浑河水系某些河段上的评价结果有较大出入,但从全流域尺度上看,P-IBI和QHEI的评价结果基本一致,表现为浑河上游的苏子河健康状况较好,而上游的浑河以及中下游的浑河干流健康状况较差.

| Abstract: | Taking the Hunhe River water system in Liaoning Province of Northeast China as a case, this paper investigated the community structure of periphyton and the physical and chemical characteristics of water environment at 62 sampling sites, and, by using the biological integrity index of periphyton (P-IBI) and the habitat environment quality index (QHEI), a health assessment on the aquatic ecosystem of the water system was conducted. There was a great spatial heterogeneity in the periphyton community structure... |
