中国斑叶蝉族昆虫地理分布格局聚类分析

分析了斑叶蝉族昆虫在中国以及贵州动物地理区的分布情况，探讨其分布格局形成、起源和演化原因。根据中国和贵州斑叶蝉族的地理分布数据，运用MEGA 6.0、SPSS 22.0和ArcGIS 10.2等软件，对斑叶蝉族昆虫的区及亚区分布进行支序聚类分析，结果表明我国斑叶蝉族现代分布中心为西部山地高原亚区、华南区的台湾亚区及滇南山地亚区，分布热点地区为西双版纳地区、海南地区和台湾地区。贵州斑叶蝉现代分布中心为黔东低山丘陵省、黔北中山峡谷省和黔南低山河谷省，分布热点地区为铜仁北部的沿河地区、遵义的务川地区及贵州黔东南州的榕江、雷山地区。斑叶蝉族昆虫中国分布区形成的顺序先是东北区，其次是青藏区和蒙新区，最后是西南区、华北区、华南区和华中区。贵州分布区形成的顺序先是黔西高原中山省和黔中山原丘陵省，其次是黔南低山河谷省，最后是黔北中山峡谷省和黔东低山丘陵省。中国分布区中，B21和B22聚类群属级阶元的相似性最高，区间关联性最强。在贵州分布区中黔东低山丘陵省和黔北中山峡谷省属级阶元的相似性最高，物种交流最为频繁。目前，斑叶蝉族昆虫的地理分布格局主要是历史气候变化、当前气候条件以及植被覆盖等生态环境共同作用的结果；区系起源和演化主要受地质构造运动作用；斑叶蝉在各区的分布相似性可能与气候变化引起的物种由南向北扩散有关。

Cluster analysis of geographical distribution patterns of Erythroneurini in China

The distribution of the tribe Erythroneurini in China and Guizhou Zoogeographical regions was analyzed, and the reasons for formation, origin and evolution of the distribution pattern were discussed. According to its geographical distribution data in China and Guizhou respectively, the cluster analysis of the distribution of Erythroneurine leafhoppers in regions and subregions was performed by using MEGA 6.0, SPSS 22.0 and ArcGIS 10.2. The result shows that the modern distribution centers of this tribe in China include the Western Mountain Plateau Subregion, the Southern Taiwan Subregion and the Southern Yunnan Hilly Subregion, and its distribution of hot spots are Xishuangbanna area, Hainan area and Taiwan area. The modern distribution centers in Guizhou are the Eastern Guizhou Lower Mountain and Hill Province, the Northern Guizhou Middle Mountain and Canyon Province and the Southern Guizhou Lower Mountain and River Valley Province. The hot spots in Guizhou are Yanhe in the north of Tongren, Wuchuan in Zunyi, Rongjiang and Leishan in Qiandongnan Prefecture. The order of formation of Chinese distribution region of Erythroneurine leafhoppers is firstly the Northeast Region, then the Qinghai-Tibet Region and the Mongolia-Xinjiang Region, and finally the Southwest China Region, the North China Region, the South China Region and the Central China Region. The order of formation of distribution region in Guizhou is firstly the Western Guizhou Plateau and Middle Mountain Province and the Central Guizhou Plain and Hill Province, followed by the Southern Guizhou Lower Mountain and River Valley Province, and finally the Northern Guizhou Middle Mountain and Canyon Province and the Eastern Guizhou Lower Mountain and Hill Province. Among Chinese distribution regions, the similarity of B21 and B22 cluster group at genera level is the highest, and the interval correlation is the strongest. In Guizhou distribution region, the Eastern Guizhou Lower Mountain and Hill Province and the Northern Guizhou Middle Mountain and Canyon Province at genera level have the highest similarity and the most frequent species exchanges. At present, the geographical distribution pattern of the Erythroneurine leafhoppers is mainly the result of interaction of the historical climate change, the current climate conditions and the vegetation cover, and so on. The origin and evolution of the fauna are mainly affected by the geological tectonic movement; the distribution similarity of leafhoppers in different regions is may be related to the spread of species from south to north caused by climate change.
