【摘要】 本文试图通过对滇南森林的区系分析,论证主要森林植物属亚洲热带森林的组成部分,但由于纬度和海拔都达到了极限范围,又具有明显的地区性特点。 文章从植被分布的一般规律出发,以森林的区系组成为重点,应用习见的50种植物和某些纯热带分布科属的具体分析,得到了滇南热带森林的分布北介,并将全部植物归并为四种分布区类型,即滇南泛热区型、滇东南热区型、滇西南热区型、滇南热区型。并以此为依据,将滇南植被区分为滇东南、滇西南和滇南三个植被小区。更多还原

【Abstract】 The authors attempt through the analysis of floral composition to demonstrate that the main forest vegetation in southern Yunnan is a part of tropical forest in Asia. However, the forest possesses obviously local characters because of the distribution have reached the limited range of the latitude and altitude.The northern limit of the tropical forest and its floral composition distributed in Yunnan has been identified by the general distribution regularity through the analysis of fifty common plants and some pure tropical families and genera. And all the plants here were incorporated into four distributional types, i. e.The general type of tropical Yunnan,The south-east type of tropical Yunnan,The south-west type of tropical Yunnan,The southern type of tropical Yunnan,According to the above data, we may divide the vegetation of southern Yunnan into three small vegetation regions, i. e. south-eastern region, southwestern region, and southern region of the vegetation in Yunnan province.更多还原
