中文摘要：
于2007年4月～11月，对崇明岛不同季节昆虫群落多样性进行调查。选取6种不同生境，分别
用物种丰富度、多样性指数、均匀度指数、相似性指数对不同的群落进行统计分析。共采集
到昆虫标本约5 800号，隶属于13目110科245种。数据表明，夏季的物种数目最
多，春季次之，秋季最少。多样性指数以夏季的公园林地最高，秋季的西沙湿地最低。均匀
度指数以春季的东滩湿地最高，秋季的西沙湿地最低。相似性指数以东滩湿地和西沙湿地相
似性最高，为0.2769；海防林和小麦田最低，为0。结果表明，昆虫多样性与其所生活的环
境有密切关系。
英文摘要： The diversities of insect communities in six kinds of habitatwere surveyed in Chongming Island in different seasons, from Apirl to November in 2007. Species richness(S), Shannonweiner biodiversity index (H′), Pielou' eveness(E) and Similarity index (Cj) were adopted to analyze the insect diversity. Approximately 5 800 specimens were collected, which belong to 245 species, 110 familis and 13 orders. The results showed that the species richness in summer was the highest, following in spring and autumn. Shannonweiner biodiversity index (H′) ofthe forest in park in summer was the highest, and that of Xisha marsh in autumn was the lowest. Pielou' eveness (E) of Dongtan marsh in spring was the highest and that of Xisha marsh in autumn was the lowest. Similarity index (Cj) was the highest (0.276 9) between Dongtan marsh and Xisha mash, and was the lowest (0) between Shelter belt and Wheat field. It indicated that the diversity of insects wasassociated with many environmental factors.
