对云南亚热带万年青阔叶林（包括中山湿润、季风和半湿润类型）的物种、多样性、结构、动态和演替等生态学特征进行了研究，并与日本西南部亚热带/暖温带万年青阔叶雨林进行了比较。云南和日本西南部森林的属和种都是东亚成分，表明两个地区的植物区系有着非常密切的关系，尽管两个地区的物种组合不同。在科、属和种水平上，两个地区的多样性指数和分类单元丰富度的数值数据相似。两地区主要树种林隙更新行为有4种类型。在这两个，作为长期的人类活动的结果，植物群落范围从先锋落叶阔叶和/或先锋针叶林到后期演替万年青阔叶林。两个地区的演替遵循平行的路径，从云南的先驱Alnus和日本的Alnus、Mallotus和Styraxin开始，伴随着两个地区的针叶松，到晚演替的万年青阔叶Cyclobalanopsis和Castanopsisas它们的最后阶段。
Subtropical evergreen broad-leaved forests of Yunnan, China, including mid-montane moist, monsoon, and semi-humid categories, were studied in terms of ecological attributes of pertinent species, diversity, structure, dynamics and succession, as compared with the subtropical/warm-temperate evergreen broad-leaved rain forest of southwestern (SW) Japan. The genera and species of the forests of Yunnan and SW Japan are East Asian elements and indicate a very close relationship between the respective floras, though different assemblages of species occur in the two regions. Diversity indices and numerical data on taxon richness at family, genus and species level were similar in both regions. Four types of gap-regeneration behaviors among the major tree species were recognized in the two areas. In both, as a result of long-term human activity, the plant communities ranged from pioneer deciduous broad-leaved and/or pioneer coniferous stands to late-successional evergreen broad-leaved stands. Succession in the two regions followed parallel paths, beginning with pioneerAlnusin Yunnan andAlnus,MallotusandStyraxin Japan, accompanied by coniferousPinusin the two areas, and with late-successional evergreen broad-leavedCyclobalanopsisandCastanopsisas their final stage.
