摘要
通过对杨树苗圃生长季节昆虫群落的系统调查,共得到27科41种11639个个体,分析比较了不同昆虫类群数量比例以及优势种随季节变化动态,并分析了个体数、丰富度、均匀度、多样性指数随季节变化的特点和机制。
Systematic investigation and analysis of insect community in the poplar nursery were carried out from April to October 2005. The results indicated that there were 11639 individuals belong to 27families, 41 species. Proportions of different groups and Seasonal dynamic of dominance species were compared. The seasonal dynamic characteristic and mechanism of individuals, species richness ,evenness and diversity index were also analyzed.
