摘要
在实地调查与标本查阅、文献检索的基础上,对湖北省分布的"国家重点保护野生植物"种类、区域分布特征及分布格局特征进行了分析研究,并对其保护现状进行了评价。结果表明,湖北省分布有国家重点保护野生植物51种;以鄂西南分布最为集中,达43种,区域性分布以种数多少排序为:鄂西南>鄂西北>鄂东南>鄂东北>鄂中丘陵>江汉平原湖泊;国家重点保护野生植物多呈零星或单株分布,以群集分布或以群集分布为主的只有15种,占总数的29.4%;目前全省自然保护区(小区)使湖北省47种国家重点保护的野生植物得到了有效保护,但易地保护工作进展缓慢,部分国家重点保护植物的保护迫在眉睫。
We discussed tern of the national key the species composition, distribution range and distribution patprotected wild plants in Hubei Province as well as assessing the conservation status, basing on the field survey, specimen records and the information from published literatures. The results show that there are 51 species of the national key protected wild plants in Hubei, among which 43 species are in the southwestern of Hubei. According to the number of appeared species in different districts of Hubei, the sequence is as follows： Southwest district） Northwest district ）Southeast district Northeast district ） Central hill district ） Jianghan Plain district. In the 51 species, most of them are sporadic or single distribution while 15 species are aggregated distribution, accounting for 29.4% of total species. At present, 47 species of the national key protected wild plants in Hubei Province have been effectively protected in nature reserves, but the ex-situ conservation is making slow progress. Of some species.
