摘要
本文利用三维生态位资料进行模糊聚央和极点排序。结果表明,苹果叶片害虫由4个集群和2个边缘种组成。群落中生态位的差异,有利于充分有效地利用资源,减小种间竞争和物种的繁衍。
The Fuzzy clustering and pole ordering of the apple leaves insectswere studied with three dimensions data,the results showed that,the co-mmunity of the apple leaves insects from Maowen county of Sichuan con-sists of four demes and two peripheral species.The difference of nichesof different species in one community is favourable not only to share theresources efficiently,but to reduce the contention among species that areof benefit to the population increasing.
