【目的】在收集汇总以往野外调查资料以及已经发表的历史文献资料基础上,归纳云南蚤类的分布特点,分析云南地理小区对蚤类的影响。【方法】在实地采集和补充文献记录基础上,对收集到的蚤类进行系统分类整理;运用SPSS13.0的主成分分析及系统聚类对数据进行处理。【结果】本研究共记录云南蚤类9科45属144种,其中古北种15种,东洋种108种,东洋、古北两界兼有种15种,广布种6种。144种蚤中,属于云南特有蚤类有75种;横断山中部小区记载蚤类122种,横断山南部小区26种,滇东高原小区41种,滇西高原小区28种,滇南山地小区25种。主成分分析和聚类分析结果基本一致,均可聚为两类:一类为横断山南部小区、滇南山地小区、滇西高原小区及滇东高原小区;另一类为横断山中部小区。【结论】云南省蚤类分布明显受到地理小区环境的影响。云南省蚤类昆虫种类繁多,蚤类的自然分布受到云南省特定地形地貌影响。
【Objective】 On the basis of collecting and summarizing past field survey data and published historical documents and data, the distribution characteristics of fleas in Yunnan were summarized, and the influence of Yunnan geographical area on fleas was analyzed. 【Method】 On the basis of collecting and supplementing the literature records in the field, the collected fleas were systematically classified and sorted. The data were processed by principal component analysis and cluster analysis of SPSS13.0. 【Result】 A total of 144 species belonging to 45 genera, 9 families, were recorded in this study. Among them, there are 15 species of ancient North China and 108 species of Oriental. There are 15 species and 6 species widely distributed in both eastern and northern China. Among 144 species of fleas, there are 75 species of fleas belonging to Yunnan; 122 species of fleas, 122 species of southern hills in Hengduan Mountains, 41 species of eastern Yunnan Plateau, 28 species of western Yunnan Plateau, Species. The principal component analysis and cluster analysis results are basically the same, can be grouped into two categories: one is the southern section of Hengduan Mountains, mountainous area in southern Yunnan, western Yunnan plateau and eastern Yunnan Plateau; the other is the middle of Hengduan Mountains. 【Conclusion】 The distribution of fleas in Yunnan Province is obviously affected by the geographical environment. A large variety of flea insects in Yunnan Province, the natural distribution of fleas affected by the specific topography of Yunnan Province.
