哈巴雪山自然保护区种子植物区系特征研究

Study on Floristic Characteristics of Seed Plants in Habaxueshan Nature Reserve,Yunnan,China

以2008年"云南哈巴雪山自然保护区综合科学考察项目"的野外调查资料为基础,按照吴征镒对中国种子植物属的分布型的划分标准,对哈巴雪山自然保护区种子植物区系科、属、种进行统计分析。结果表明,哈巴雪山自然保护区具有种子植物120科555属1 633种,包括中国种子植物属的15个分布类型和20个变型。除世界分布科外,泛热带分布型和北温带分布型科是保护区植物的重要组成部分。其中,热带分布158属,温带分布322属,中国特有19属,分别占非世界广布属的31.66%、64.53%和3.81%。哈巴雪山保护区植物区系含温带区系性质,具有丰富的物种多样性,反映了哈巴雪山种子植物区系来源的广泛性与复杂性。

Based on field investigation data of scientific investigation in the Habaxueshan Nature Reserve in 2008, the floristic characteristics of seed plants in the Nature Reserve are studied from the levels of species, genus and family according to Wu-zhengyi about genera distribution types of Chinese seed plants. The results show that there are 120 families, 555 genera and 1 633 species of seed plants in the Habaxueshan Nature Reserve including 15 are- al types and 20 subtypes of seed plants. In addition to the cosmopolitan, pantropic and north temperature are the important components of the total genus. Among of them, there are 158 genus of the tropic, 322 of the temperature and 19 of Chinese endemic genera, accounting for 31.66 % , 64.53 % and 3.81% of non cosmopolitan respec- tively. The flora in the Habaxueshan Nature Reserve shows obvious temperate character with rich diversity and com- prehensive sources.
