| 摘 要： | 结合文献资料研究和在各地开展荨麻科植物调查,对荨麻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数据处理,结果表明:该科植物的分布中心在滇、桂一带;特有性中心在台、滇、藏、桂等地;相似性系数较大是地理上相近、环境异质性较小的地区;垂直分布中心为500～2 000m;水平分布中心为东经90°～120°和北纬20°～35°.受地理环境、气候因素等影响,荨麻科植物主要分布在高原地区,平原、丘陵地区种植较少,且品种缺乏.

| Abstract: | Through investigation of the Uticaceae plants all over,combining with the document material research,their species richness,species endemic index,similarity coefficient,vertical and horizontal distribution are studied in this paper.The results showed that Yunnan and Guangxi areas were its distribution center;Taiwan,Yunnan,Xizang and Guangxi is its endemic centers.While similarity coefficient areas are those which have geographic proximity but smaller environmental heterogeneity;The vertical distribution center is 5 00-2 000 meters above sea level,while the horizontal distribution center is 20 °-35 °N and 90 °-120 °E.The influence of climate and geographical environment factors,the Uticaceae mainly distributed in plateau areas,plain,hilly area plants less,and is lack of variety. |
