生态系统碳循环对温度的响应是全球变化生态学的重要研究内容之一。总初级生产力(GPP)随着温度的升高而升高,在最适温下达到最大值(GPP_(max)),之后随温度的升高而保持不变甚至下降,因此GPP_(max)代表着最适温度下的植被光合潜力。然而,关于森林生态系统GPP_(max)的时空分布和影响因子仍不清楚。本文以中国东部南北森林样带(NSTEC)上的长白山温带针阔混交林、会同亚热带杉木人工林、千烟洲亚热带常绿针叶人工林、鼎湖山亚热带常绿针阔混交林和西双版纳热带季雨林等5种典型生态系统为对象,利用涡度相关技术分析森林GPP_(max)的时空规律及其主要影响因素。结果表明:在所有森林生态系统中,GPP对温度...

The response of ecosystem carbon cycle to temperature is one of the major topics in the research field of global change ecology. The general pattern of the response of gross primary productivity (GPP) to temperature usually shows that GPP increases with temperature at the lower temperature range to reach a maximum value (GPPmax), and then declines as temperature increases f urther. Thus, GPPmax represents the photosynthetic potential of vegetation at the optimum temperature. However, our understanding on the spatial and temporal patterns and ma...
