西双版纳热带雨林具有较高的植物区系多样性，与马来西亚热带雨林在植物群上有密切的亲缘关系。与低地潮湿的热带地区相比，这种森林通常不会在西双版纳这样的气候地区建立（降水少，气温低）。年平均降雨量为1487毫米，远低于世界其他地区的热带雨林。辐射雾的频繁出现可能对植物的水分关系和这类雨林的水文循环起着重要作用。然而，辐射雾的多重水文和生态效应还没有得到很好的理解。本文描述和分析了辐射雾对西双版纳热带雨林的意义，并提出了辐射雾对西双版纳热带雨林的存在起重要作用的假说。最后对进一步研究雾的意义提出了建议。
The tropical rain forest in Xishuangbanna, SW China has a high floristic diversity and is closely related to Malaysian rain forests in flora. This forest would not normally be established in such a climatic region as Xishuangbanna (less precipitation and lower air temperature) compared to those of the lowland moist tropics. The mean annual rainfall is 1487 mm, which is considerably lower than rain forests in other parts of the world. It is believed that the frequent occurrence of radiation fog might play an important role in the water relations of plants and in the hydrological cycle of this type of rain forest. However, the multiple hydrological and ecological effects of radiation fog are not well understood. In this paper, we describe and analyze the significance of radiation fog to this forest, and develop a hypothesis that fog plays an important role in the presence of the tropical rain forest in xishuangbanna. Suggestions for further research on the significance of fog are offered.
