STUDIES ON THE TEMPORAL STRUCTURE AND DYNAMIS OF THE INSECT COMMUNITIES IN GARDENS
园林昆虫群落时间结构及动态研究

The variation of species and individual numbers of the insect communites in four types of garden plants were investigated over one year.The principal component analysis and the optimal sorting method were used for studying the main factors and the temporal patterns of the insect communities in the course of seasons.The results showed that the insect community had a more compliated composition,less fluctuations,more obvious main factors and temporal patterns in the complex plant type than those in the simple plant type.In the simple plant type,the composition of the insect community was simple and fluctuated greatly.Its main fators and temporal patterns were not obvious.
