The rare and endangered plants and their conservation policies in Jiuwan Mountain of Guangxi

通过对广西九万山植物资源的考查和研究 ,发现该地区分布有珍稀濒危植物 1 9个科 ,2 8个属 ,共 2 9种。其中国家一级保护植物有 5种 ,国家二级保护植物有 2 4种。对它们的种类组成、区系成分、地理分布进行了分析 ,结果显示出广西九万山珍稀濒危植物不仅种类繁多 ,而且具有古老、原始、孑遗特性 ,热带性质明显 ,中国特有现象极为突出等特点。据此提出对广西九万山珍稀濒危植物的保育对策 ,以便更好地保护其生物多样性和这些珍稀濒危植物资源的可持续利用。

According to the study and investigation of the plant resource in Jiuwan Mountain of Guangxi, we have found that the rare and endangered plants exist in 19 families and 28 genus, summing up 29 species, among which there are 5 species for the first class conserved plants of China, 24 species for the second class. The paper analyzed the species component, zone system and geological distribution of the plants mentioned above.
