中国平腹蛛科蜘蛛地理区划初探

Preliminary Studies on the Zoogeographic Divisions of Chinese Ground Spiders(Araneae:Gnaphosidae)

运用聚类分析方法对中国166种平腹蛛科蜘蛛的地理分布进行初步探讨,分析比较了中国7个动物地理区中的15个亚区组分相似性。结果表明,华北区的划分基本符合中国平腹蛛科蜘蛛的分布特点,而其他区则有不同亚区间的重组。东北区的大兴安岭亚区与蒙新区的东部草原亚区、西部荒漠亚区,蒙新区的天山山地亚区与青藏区的羌塘高原亚区、西南区的西南山地亚区,华中区的东部丘陵平原亚区、西部山地高原亚区与华南区的闽广沿海亚区、滇南山地亚区分别聚合;东北区的其他2个亚区则自成一个区;青藏区的青海藏南亚区独立成一支。

This paper aims to carry out the preliminary study on the zoogeographic distributions of 166 species within Gnaphosidae by clustering method,and analyze and compare the similarities of 15 subregions in seven zoogeographic regions in China.The results suggested that the division of Northern China was coincident with the distribution pattern of Chinese ground spiders,but there was subregion recombination between the other regions.There was aggregation between Da Hinggan Mountains subregion in the Northeast,east plain subregion in Mengxin area and west hungriness subregion,between Tianshan mountainous subregion in Mengxin area,Qiangtang altiplano subregion and the southwest mountainous region subregion in Southwest,and between east hill plain subregion in central China,west mountainous region altiplano subregion,Min and Guang coastal subregion in south of China and south Dian mountainous region subregion.The other two subregions in the Northeast formed a region.Qinghai and south Xizang subregion in Qinghai-Xizang Region formed a branch independently.
