摘要:

该文针对“西双版纳热带山地雨林的植物多样性研究”论文中存在的一些问题进行了讨论。原文所依据的6个调查样地, 从其分布海拔、生境、群落的生态外貌特征、植物区系组成及单位面积植物种数的统计上反映出它们并非都属于同样的植被类型,即原文所称的热带山地雨林,而可能分别属于《云南植被》中所应用的热带季节雨林的次生林群落(样地I和II)、季风常绿阔叶林群落(样地V和VI)及类似于苔藓常绿阔叶林(样地III和IV)的群落类型。由于这些样地代表了不同的植被类型, 导致在对这些样地的植物多样性特征的比较上出现较大差异。对原文在资料分析和与其它森林群落植物多样性的比较上存在的一些问题也作了讨论。原文的研究结果显示了西双版纳不同海拔高度上森林植物群落的物种多样性特征,但并不能全部运用于该地区的热带山地雨林这一特定植被类型。

Abstract:

This paper discusses the results of a previously published paper on the plant diversity of the tropical montane rain forests in Xishuangbanna, which was based on six sampling plots. The six plots are from quite different habitats at different altitudes and with conspicuously different physiognomic, floristic and species richness characteristics and actually represent different classification types of vegetation. Based on the vegetation classification of Yunnan suggested by Wu (1987), plots I and II, which are dominated by Millettia leptobotrya (Papilionaceae), could represent a secondary tropical seasonal rain forest in the region. Plots V and VI, which are dominated by species of Lauraceae and Fagaceae, could represent the so-called monsoon evergreen broad-leaved forest, while plots III and IV, which are in the upper montane cloudy zone with dense epiphytic moss plants on the trees, could be a type similar to the mossy evergreen broad-leaved forest. Some other problems in the data analysis and comparisons of biodiversity among the different forest types in the paper also are discussed. However, the results presented in the paper did reveal some characteristics of plant species diversity along altitudinal gradients in tropical montane forests in Xishuangbanna, but the data could not be used for explaining plant diversity of the particular vegetation type of the tropical montane rain forest in Xishuangbanna, Southern Yunnan.
