摘要
汇总世界医学昆虫76科4544属的分布信息,按照地形、气候等生态条件将世界陆地分作67个基础地理单元,用申效诚等提出的相似性通用公式和多元相似性聚类分析法进行定量分析,得到7个大单元群和20个小单元群的聚类结果,明显优于传统的单链法、类平均法和离差平方和法。聚类结果与以植食性为主的世界昆虫相同,而与华莱士的哺乳动物地理区划有较大差异。为解释这个看似矛盾的结果,用同样方法对世界动物、植物、微生物进行定量分析,证实了医学昆虫与各大类生物间具有相同的分布格局,这不仅说明新生代的生态环境对各类生物分布影响的同质性,而且提出了建立统一的世界生物地理区划系统的可能性。
Summarize the medical insects’ distribution information of 76 families, 4544 genera. Divide land in the world into 67 basic geographic units according to the topography, climate and other ecological conditions. With Shen’s similarity general formula and diversity such as Xiao-cheng Shen nultivariate similarity clustering analysis method for quantitative analysis, get seven big unit groups and 20 small unit groups of clustering results, is superior to the traditional single linkage method, average group linkage method and sum of squares method. The clustering result is the same as the main plant feeding the world of insects, and has a bigger difference with Wallace’s mammals’ geographic area. To explain this seemingly contradictory result, in the same way for quantitative analysis to the world’s animals, plants, microorganisms, confirmed the medical insects and these different kinds of creatures with the same distribution pattern, which not only account for the Cenozoic Era of ecological environment on the influence of all kinds of biological distribution homogeneity, and put forward the possibilities of establishing unified world biological geographical regionalization system.
