Evaluation of correlation between macrobenthos distribution diversity and environment factors in Jinghang Canal(Zhenjiang part)
This study selected river of Jinghang Canal(Zhenjiang part)as the research object to investigate the distribution and diversity of macrobenthic animals.This research analysed the relationship between species diversity and environmental factors based on the data of TP,NH3-N,etc.and method of multivariate statistical analysis.The results showed small difference of water quality in Zhenjiang part,and large difference of benthic animal species structure.The overall water quality of the eight sites was classⅡlevel(surface water)among which the TP and Limnodrilus hoffmeisteri of Sanchahe River was the highest in the eight point.The results of RDA analysis showed that environmental factors of NH3-N,COD,chlorophyll a,TP mainly affected species diversity.
