Relation ship between plant community and insect community in Korean pine broad-leaved mixed forest of Changbai Mountain

Abstract

Abstract: The plant,insect community and their correlation were studied systematically through seasonal research in this paper.The results showed that the index of species richness of forest plant community was negatively correlated with community of defoliator and parasitic insects,positively correlated with predatory insect community.The evenness of insect was related to that of plants closely.Annual species diversity index of forest plant community showed a closely positive correlation with that of predatory and parasitical insect community,and a negative correlation with defoliator insect community.Distinct correlation was found between forest plant and forest insect community suggesting that complexity of forest plant community had significant influence on diversification of insect species composition.
