Abstract: The macroinvertebrates and water physical and chemical environmental factors were surveyed at 65 sampling sites in Huntai River， China， in spring of 2012， in order to study the differences of environmental factors affecting the community structure of macroinvertebrates in different freshwater ecosystem function regions of Huntai River.The results showed that there were significant differences in species composition and indicator species of macroinvertebrates in three freshwater ecosystem function regions of Huntai River，with significantly differences in Shannon-Wiener diversity index，Pielou evenness index and species-richness index of macroinvertebrate in three freshwater ecosystem function regions of Huntai River and in the environmental factors of different freshwater ecosystem function regions(P＜0.05).Canonical correspondence analysis revealed that altitude， water depth and total nitrogen were of the driving factors in freshwater ecosystem function regionⅠ，that potassium permanganate index，and salinity in the freshwater ecosystem function regionⅡ，and that dissolved oxygen，conductivity，and salinity in freshwater ecosystem function regionⅢ.Correlation analysis indicated that Shannon-Wiener diversity index was significantly correlated with altitude and total nitrogen(P＜0.05)；Pielou evenness index was significantly correlated with potassium permanganate index(P＜0.05)， and species richness was significantly correlated with altitude and levels of dissolved oxygen， and total nitrogen(P＜0.05)in freshwater ecosystem function region I.In freshwater ecosystem function regionⅡ，however，there was no significant correlation between environment factors and Shannon-Wiener diversity index(P＞0.05)，with significant correlation between sea level， conductivity， salinity， and total dissolved solids and Pielou evenness index(P＜0.05)， and between altitude and species richness(P＞0.05).No significant correlation between environmental factors and these indices was found in the freshwater ecosystem function regionⅢ.The findings indicate that there are spatial heterogeneity in community structure of macroinvertebrate and in environmental factors influencing the community structure of macroinvertebrates in different freshwater ecosystem function regions in Huntai River Basin.
