A Research Method for Species Diversity of Plant in Seasonal Tropical Rainforests in Xishuangbanna.

一、方法1.样地的选择样地分别选取热带干性季节雨林的典型代表——以箭毒木(Antiaris toxicaria)、龙果(Pouteria grandifolia)为标志的群落,以千果榄仁(Terminalia myriocarpa)。

Shannon-Wiener diversity index is used in the species diversity research for 3 forest commu-nities in Xishuangbanna.Its effectiveness for seasonal tropical rainforests is tested at thefirst time.This index of seasonal tropical rainforests in Xishuangbanna is about 5.500.The species diversity increases from seasonal dry to seasonal humid tropical rainforests.Shannon-Wiener diversity index is proved to be suitable for the communities of seasonal tropi-cal rainforests in Xishuangbanna.
