白马山自然保护区国家珍稀濒危植物资源调查研究

根据《中国植物红皮书》(第1册)和《国家重点保护野生植物资源名录》,白马山自然保护区有珍稀濒危植物共计37科44属49种(不重复计算,包括归化种),其中蕨类植物3科3属3种,裸子植物6科6属7种,被子植物28科35属39种,占四川省珍稀濒危植物总数的46 67%,占全国珍稀濒危植物总种数的12 63%.按生活型划分有木本植物29种,草本20种.本区珍稀濒危植物具有古老孑遗性,单型科(属)、少型属占绝大多数,中国特有属比例较大,占总属22 73%.白马山自然保护区也是银杉生态研究的理想基础.

A floristic study of the rare and endangered plants in Baimashan nature reserve

According to the Red Book of Chinese Plants (Vol.1) and the national important wild conservative plants list, there are 49 species of 44 genera in 37 families of the rare and endangered plants in Baimashan Nature Reserve. Among them ,there are 3 species of 3 genera in 3 families of Pteridophyta; 7 species of 6 genera in 6 families of Gymnosperm,taking up 39 species of 35 genera in 28 families of Angiosperm. 46.67% of all the rare and endangered plant species in Sichuan Province and 12.63% of such taxa in China. Classified in terms of growth types,there are 29 species of wooden and 20 species of herb. The rare and endangered plants in this area are characterized by ancient origin and the dominance of monotypic families and monotypic genera. The endemism to China is obvious, accounting for 22.73% of the total genera, and Baimashan Nature Reserve is an ideal basis for studying the ecological environment of Cathaya argyrophylla.
