上海市河道底栖动物群落结构与环境因子的关系
The Community Structure and Their Relationships of Zoobenthos with Environmental Factors in Shanghai Urban Rivers
摘要
Abstract
To study the relationship of the spatial distribution and indicator species of the Zoobenthos with environmental factors. We have monitored of total nitrogen, total phosphorus, potassium permanganate index, pH, temperature, dissolved oxygen, chlorophyll a and salinity of Shanghai urban rivers, and analyzed the spatial distribution, species number and biomass of zoobenthos. The results show that: the adaptability and sensitive of different kinds of zoobenthos to the environment is distinct. The pH, dissolved oxygen, total nitrogen and salinity in the eight kinds of environment factors, affected spatial distribution and biomass of Zoobenthos ,is the main influence factors. Limnodrilus hoffmeisteri, Branchiura sowerbyi, Limnodrilus grandisetosusNomurawith the total nitrogen, total phosphorus, potassium permanganate index and chlorophyll a have a significant correlation, is indicator species of severe eutrophication in Shanghai's river;Tylorrhynchus heterochaetus,Neocaridina denticulatedenticulata,Curuphiurn voluruturwas a significant associated with water dissolved oxygen, but with total nitrogen, total phosphorus, potassium permanganate index were significantly negative correlation, can be used as indicator species of river light pollutioned in Shanghai. Environmental factors affected zoobenthos is the comprehensive effect of many factors, the interaction of different environmental factors determines the distribution and biomass of zoobenthos, therefore, the community structure and spatial distribution of zoobenthos has intuitive reflect to the comprehensive situation.关键词
