摘要
就地保护即建立自然保护区是保护珍稀濒危野生植物的最佳手段。本研究以文献资料为基础,分析了截至2008年我国建立的国家级自然保护区对已正式颁布的《国家重点保护野生植物名录(第一批)》中所列物种的就地保护状况。在全国尺度上,国家级自然保护区共保护国家重点保护野生植物237种(含变种),占总数的80.07%。其中I级保护植物56种。在省级尺度上,云南、广西、四川、贵州、湖南5省区国家级自然保护区内分布的国家重点保护野生植物数量最多。通过分析各省区未受到国家级自然保护区保护的重点保护野生植物分布状况,提出了国家重点保护野生植物就地保护的热点地区。
In situ conservation, that is, the establishment of nature reserves, is the best means to protect rare and endangered wild plants. By collecting and analyzing the distribution information on state key protected wild plants, we investigated the protected conditions of these species within the national natural reserves as of 2008 based on the data available in China. The results indicated that totally 237 state key protected wild plant species (including varieties) have been protected in the national natural reserve system, accounting for 80.07% of the total amount and including 56 species listed in Class I. At the provincial level, national nature reserves in Yunnan, Guangxi, Sichuan, Guizhou and Hunan provinces contributed the most to the protection of state key protected wild plants. We also determined the major distribution areas of these protected wild plants and pointed out the hot spots for in situ conservation by analyzing distribution conditions of protected plants unprotected by national nature reserves in provinces.
