中国卫矛科植物地理分布

Geographical Distribution of Plants of Celastraceae in China

对中国卫矛科植物的物种丰富度、特有性指数、相似性系数、垂直分布和水平分布进行了系统的研究。结果表明：卫矛科植物的分布中心在滇、川、黔、桂、粤、鄂、湘一带；特有性中心在琼、桂、滇、藏、台、川等地；相似性系数较大的是地理上相近、环境异质性较小的地区；垂直分布中心为500～2000m，水平分布中心为东经90°-120°和北纬20°～35°。

Species richness, species endemic index, similarity coefficient, and vertical and horizontal distribution of plants of the family Celastraeeae are studied systematically. Results show that plants of Celastraceae are mainly distributed in Yunnan, Siehuan, Guizhou, Guangxi, Guangdong, Hubei and Hunan Provinces. However, their endemic centers are usually in Hainan, Guangxi, Yunnan, Xizang, Taiwau and Siehuan. The similarity coefficient of plants of Ce/astraeeae is mostly affected by geographic locality and environmental heterogeneity. Tile vertical distribution center occurs at elevations ranging from 500-1 500 meters above sea level, and the horizontal center is located at 90-120 degrees east longitude and 20-35 degrees north latitude.
