摘要
大型固定样地是研究生物多样性、群落系统演化和生态系统功能的重要平台。本文选取西双版纳、鼎湖山、古田山和长白山四个具有代表性的中国森林大样地,按照吴征镒等的方法,分析了不同大样地种子植物科、属和种三个层次的分布区类型。发现热带西双版纳大样地具热带北缘的地理性质;南亚热带鼎湖山大样地呈现出由热带向亚热带过度的特点;中亚热带古田山大样地各分布区类型所占的比率均与全国水平接近,显示出典型的亚热带特征;温带长白山大样地具温带性质。表明中国森林随着纬度的变迁,种子植物区系成分也随之发生显著的变化,这证实了前人有关中国种子植物区系的研究结果,同时也说明通过大样地平台进行植物区系跨区域和比较性研究,方法可行,结果可信。
Large scale permanent plots (LSPP) work as important platform for long-term research on biodiversity, community phylogenetics and evolution, and ecosystem function in forests. The paper selected four Chinese forest dynamics plots representing four climatic types of Chinese vegetation (Xishuangbanna in tropics, Dinghushan in southern subtropics, Gutianshan in middle subtropics, and Changbaishan in temperate zone) to analyze the areal- types of seed plants at the level of family, genus, and species, according to the approach of Wu et al. The results showed that Xishuangbanna was characteristic of the margin of tropical flora, Dinghushan was characteristic of the transition from tropical flora to subtropical flora, Gutianshan being characteristic of typical subtropical flora, and Changbaishan being characteristic of temperate zone. These results were consistent with previous findings in Chinese forests, exhibiting distinctly geographic distribution of Chinese genera along altitude gradient, which indicated that the comparatively floristic analysis of multi-region, benefiting from the LSPP platform sharing original data, was tes- tified to be feasible and effective.
