As China＇s major planting base for rubber trees （Hevea brasiliensis）,Xishuangbanna in southwest China＇s Yunnan Province has made tremendous contributions to the national economic growth. However, because the lands suitable for rubber plantations are largely distributed in tropical rainforests,the increasing rubber plantations have led to the acreage reduction of the local rainforests. These may irreversibly alternate the local ecological and environment systems, producing direct or indirect impact on climate. Of them, the changes in atmospheric chemistry are caused by the differences between biogenic volatile organic compounds （VOC） from rubber plantations and those of natural vegetation.
