摘要
首批中国珍稀濒危植物分布于湖南的有65种4变种。从区系组成、植物地理分布、在自然森林群落中的生态地位,以及利用价值等方面分析了它们的特征,并对湖南珍稀濒危植物就地保护的有效性和措施进行了讨论。
Features of first announced Chinese rare and endangered plants(REP) distributed in Hunan Province, which have 65 species and 4 varieties, were analyzed. The results showed; 1. REP species are so rich that the task to protect them is arduous;2. Their genera can be divided into 9 distributing types and Chinese endemic and Asian tropical types are the most of all types, occupying 57.8% and indicating their tropical feature;3. Much more genera including 1 or 2-9 species and their ancient origin,display the high protected value; 4. Those plants mainly exist in marginal areas and mountains in the province. As accompany species or subordinate species they are closely dependent on forest environment; 5. The available values lead to them to easily destroyed directly; 6. Correspondence between distribution of REP with arrangements of the nature reserves suggests that REP is able to be protected in-situ effectively, if those nature reserves can give off protective functions.
