IPCC(2007)预计在21世纪末,全球平均温度将会升高1.1℃至6.4℃[1]。在过去的20年中,全球相继开展了大量的增温控制实验,预测各类生态系统对全球变暖的响应。据已发表的文献统计分析表明,目前野外增温控制实验主要集中于温度受限制的中高纬度地区[2-3],在30°N以南的热带和亚热带地区还几乎没有主动性控制增温实验[4-6],这限制了对全球变暖如何影响亚热带和热带生态系统的认 IPCC (2007) predicts that by the end of the 21st century, the global average temperature will rise 1.1 ℃ to 6.4 ℃ [1]. In the past 20 years, a large number of global warming control experiments have been conducted around the world to predict the responses of various ecosystems to global warming. According to the published literatures, statistical analysis shows that at present, experiments of field temperature control mainly focus on medium and high temperature regions with limited temperature [2-3]. In the tropical and subtropical regions south of 30 ° N, there is almost no increase in active control Temperature experiments [4-6] have limited the recognition of how global warming affects subtropical and tropical ecosystems
