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。
In this paper, we use the three-dimensional niche data to carry out fuzzy centralization and pole ordering. The results showed that apple leaf pests consisted of 4 clusters and 2 marginal species. The differences in niche in the community are conducive to full and effective use of resources, reducing interspecific competition and species multiplication.
