摘要
通过对云南省自然保护区榕属(Ficus)植物资源的调查以及相关资料的查阅整理,统计出云南省自然分布的榕属植物共有73种32变种,比《云南植物志》、《云南种子植物名录》记载的增加了2种3变种.发现其水平分布以滇南区域分布种类最为集中,榕属植物的分布数量随着纬度升高而数量减少呈现负相关的一致性.在垂直分布上以海拔500~1500m的山地、沟谷等地榕属植物种类分布最广,资源最为丰富.
Based on the investigation and by consulting relevant data of resources of Ficus plants in typical Nature Reserve of Yunnan Province,we find that the Ficus plants of natural distribution in Yunnan Province involve 73 species and 32 varieties,an increase of 2 species and 3 varieties more than recorded in The Flora of Yunnan Province and List of Seed Plants in Yunnan Province.We also find the species of horizontal distribution are most concentrated in southern Yunnan Province and the number of the Ficus plants is reducing with increasing latitude.The Ficus species of vertical distribution are most widely distributed in mountains and valleys with altitude of 500 - 1 500 m,and the resources are most abundant.
