中国扁叶甲属地理分布格局研究(叶甲科,叶甲亚科)

Geographical Distribution of Genus Gastrolina in China (Chrysomelidae:Chrysomelinae)

本文运用GIS技术研究扁叶甲属Gastrolina在中国的地理分布格局。以采集地的行政单元转换地理坐标与动物地理区划图叠加后产生叶甲的地理分布图。结果显示此属主要分布在华中区、华北区、华南区、西南区、东北区。根据地理分布图及有关分析,认为华中区中部、华北区西北部是该属的丰富度中心和分布中心,华中区中部为中国扁叶甲多样性中心和分化中心。

The geographical distribution of the genus Gastrolina （Chrysomelidac ： Chrysomelinae） in China was analysed using GIS software. A distribution database of Gastrolina species was compiled based on specimen collection localities. This was overlapped with zoogeographic regions to develop distribution maps. Gastrolina mainly occurrs in the Central China, North China, South China, Southwest China and North China. Based on the geographical distribution and statistical analyses, central part of Central China and northwest North China are likely center of distribution, and the central part of Central China is diversity and differentiation center of this genus.
