摘　　要：本文以云南西部横断山区（约北纬21°00′～29°00′；东经97°30′～102°00′）为研究的空间范围和尺度，在该区域蚤类区系和物种多样性系列研究及调查数据的基础上，应用Pearson线性相关分析法，就蚤类的科、属、种多样性空间分布特征及其关系进行分析和探讨。结果发现，横断山区蚤类多样性随着纬度、海拔梯度和气候环境的变化，它们的组成和分布明显不同。比较而言，蚤类科、属、种丰富度在北纬25°00′～27°00′N之间较高；蚤类科、属在海拔2500～2900 m之间最高，而物种丰富度在海拔2500～3800 m之间最高。分析显示：（1）在北纬21°00′～29°00′之间水平梯度带的分布中，蚤类物种-属-科丰富度之间均呈显著相关，其中物种-属和属-科丰富度之间呈极显著相关，而物种-科丰富度之间呈显著相关，前二者大于后者；（2）在海拔500～5000 m之间垂直梯度带的分布中，蚤类物种-属、属-科丰富度之间呈显著相关，而物种-科丰富度之间的关系不显著；（3）8个山峰不同森林植被带蚤类科、属、种丰富度之间相关度与多样性指数之间关系的分析显示：蚤类科-属、科-种丰富度的相关性与物种多样性指数之间都呈负相关，而属-种丰富度相关性与物种多样性指数之间呈正相关，但他们的相关性均不显著。横断山区（局部地区）蚤类科、属、种丰富度随着纬度、海拔梯度和气候环境的变化其分布特征各不相同，但是，蚤类科、属、种丰富度之间沿纬度或海拔梯度的空间分布上都有着基本类似的正相关关系。此外，不同山峰（局域）蚤类科、属、种丰富度之间相关性并非一致及其与物种多样性指数关系并不密切。它们共同反映了横断山区蚤类科、属、种多样性空间分布特征，协同进化的趋势、差异以及环境因素对它们的影响。To probe and study the relationship between the species, genus or family of fleas and spatial distribution patterns in Hengduan Mountains of Yunnan Province.Based on investigation of fleas in Hengduan Mountains of Yunnan （ latitude：21°00′-29°00′N; east longitude： 97°30′-102°00′E）, we applied the Pearson linear correlation analysis to compare and analyze the problems of species diversities and spatial distribution patterns of fleas in Hengduan Mountains in Yunnan Province.The results showed that the composition and distribution of fleas was significantly different along with altitude , latitude gradients and climate environment.In comparison, family, genus and species of flea richness were higher in northern latitude 25 °00′-27 °00′N; Family-genus of fleas species richness was the highest in between 2500-2900 meters, but species richness of fleas was the highest in between 2 500-3 800 meters.Distribution of 8 latitude gradients zones of fleas （latitude： 21°00′-29°00′N）, species richness of genus, family and class strongly correlated with each other.Species richness of species-genus and family-genus was very significantly correlated, species richness of species was very correlated with that of family, the former is much larger than the latter; Distribution of 10 altitude gradients zones of fleas （ altitude：500 -5 000 m ） , between the change of species-genus and family-genus has very significantly positive correlation respectively.there are not obvious of change of species-family; The relationship between the correlation of flea richness and species diversity in different peaks from Hengduan Mountains of Yunnan .There was a negative correlation between family-genus of fleas and species diversity, the between family-species and species diversity do, there was a positive correlation between genus-species of fleas and species diversity in 8 different locations from Hengduan Mountains of Yunnan Province.The composition and distribution of fleas was significantly different alo
