摘　　要：通过查阅相关文献并进行统计,确认湖北特有种子植物共计129种,无特有属分布。129种植物隶属于45科92属,其中含4种以上的科共有10个,含特有种最多的科为蔷薇科,共有7属15种。特有种以草本植物占绝对优势,藤本植物最少。按地理分区,可将129种植物归入5个区,其中包含种类最多的为大巴山区(仅神农架地区至少就有17种),大别山区和幕府山区的特有种极少。基于湖北与湿地、森林植被有关的自然保护区和特有植物的模式产地进行作图,结果显示,保护区的分布范围和密度与特有植物的分布基本重合,说明绝大部分特有种在保护区内都能得到有效地保护。Based on existing literature and specimen examination,we confirme that there are 129 species of seed plants endemic to Hubei,but no genera. These species belong to 45 families and 92 genera. Ten families contain more than four species,with Rosaceae containing seven genera and 15 species. Almost half of the species are herbs（48.06%）,with a few lianas and climbers（12.40%）,and a small number of trees and shrubs. According to geographical division,the 129 species could be classified into five areas. Half of the endemic species（65）are preserved in Daba Mountains,with 17 species,at least,preserved in Shennongjia. The relevance between the scope of the 65 Hubei Province nature reserves and the distribution of endemic species was analyzed,which showed that most endemic species would receive effective conservation in the protected territories.
