摘要
根据《国家重点保护野生植物名录 (第一批 )》、《中国植物红皮书》及《濒危野生动植物种国际贸易公约》统计 ,五指山自然保护区共有保护植物和珍稀濒危植物162种 ,隶属于33科92属 ,其中国家重点保护野生植物29种。本文对各类保护植物的生活型、分布特征及地理区域特点进行了分析 ,结果表明大多数的种类为热带区系成分 ,而且在保护区内的热带低地雨林分布最为集中 ,栖息地易受到人为活动的干扰 ,需加强管理。同时 ,对五指山自然保护区内这些保护植物的价值进行探讨 ,并就如何加强保护提出了建议。
Based on List of key wild plants under state protection, Chinese plant red data book and CITES, there are 33 families, 92 genera, and 162 species of rare, endangered and protected plants among which there are 29 key wild plants under state protection (Table 1). The life form and distribution characters of the protected plants were analyzed. The results showed that most of them were tropical elements, largely distributed in tropical lowland rain forest (Table 2 and Table 3). Those areas are easy to be disturbed, so protection should be strengthened. We also discussed the value and importance of the protected plants, such as the importance on systematics, economic value, species close to importance crops and the significance on protecting biodiversity. Finally, some measures and proposals on how to protect the plants were brought forward, such as ex situ conservation, in situ conservation.
