| 摘 要： | 脐橙树冠各部位的昆虫种类相同。群落物种个体数的差异,东、南、西、北比上、中、下和内、外部位小。内层的群落结构稳定性较其它各部位差。按群落聚类分析和双轴系统的二维排序的结果,初步提出了树冠各部位不同昆虫群落沿着环境梯度变化的速率和群落相异值水平的指标。

| Abstract: | Although insect species on navel orange canopy are identical, the individuals of species between the inside and the outside level are more different than those on various directions of East, South, West and North of the tree.Analysis based on Hurlbert diversity index shows that the community stability of inside level is less than the outside one.Community similarity is conducted by counting community coefficient separately.According to the cluster analysis and two-dimension ordering, an index is suggested to indicate the insect community of different level varied with enviromental grade and community hetesogeneity. |
