摘　　要：珍稀濒危野生植物的保护是生物多样性保护研究的热点问题之一,有关濒危物种分布区的研究对于生物多样性保护理论具有重要意义。以1999年国务院颁布的《国家重点保护野生植物名录(第一批)》中所列物种为研究对象,基于文献资料与标本数据,以县域为单位,对国家重点保护野生植物在县级水平的地理分布进行研究,可知国家重点保护野生植物分布不均匀,主要分布于我国1 228个县级单位地域内且集中分布在西南地区部分县域内。通过各县域分布的国家级自然保护区所保护的国家重点保护野生植物数量,得到其在县级水平的就地保护现状:有520个县域内分布的国家重点保护野生植物受到该县域内的国家级自然保护区的就地保护,1 004个县域内分布的国家重点保护野生植物未受到国家级自然保护区的保护。最后,根据各县域未受到保护的重点保护野生植物数量,指出我国国家重点保护野生植物应加强就地保护的热点县域。The conservation of rare and endangered wild plants is a hot topic of biodiversity conservation research and the study of their geographic distribution is of significance to the theories of biodiversity conservation. The research object of this study focuses on the species in the ＂List of National Protected Key Wild Plants＂（ first batch） that was promulgated by the Chinese State Council in 1999. Based on the literature material and specimen records,geographic distribution at the county level of national key protected wild plants in China was analyzed,which are unevenly,distributed in 1228 counties and concentrate in a few counties of southwestern China. We also determine the in situ conservation status by analyzing the numbers of national key protected wild plants protected by national nature reserves. There are 520 counties where national key protected wild plants are protected by national nature reserves,and still 1004counties where national key protected wild plants are unprotected by national nature reserves. Furthermore,we point out the hot spots for on-site conservation should be strengthened by analyzing distribution status of national key protected wild plants unprotected by national nature reserves in counties.
