摘要
陆地植被的年净第一性生产力是植物每年通过光合作用所固定的碳总量。在全球CO2浓度持续变化的过程中 ,作为一个对外界综合环境因素敏感的指标 ,陆地植被净第一生产力的变化及与环境因子之间相互作用的机制是关注的焦点。简要介绍了植被净第一生产力研究方法的状况 ,着重对当前 2种主要生产力模型 (GLO PEM模型和NASA CASM模型 )的测定原理、方法、测定结果及优缺点进行了评述 ,同时对国内相关领域的研究状况也进行了介绍。表 2参 1
Annual net primary productivity(NPP) of terrestrial vegetation is the net amount of carbon fixed by plants through photosynthesis in one year.As a sensitive index to environmental factors,NPP of terrestrial vegetation and its relationships with environmental factors have been paid much attention during the past years due to rising CO 2 concentration and global climate change.Studies on NPP are reviewed in this paper,especially on the principals,methods,characteristics and results of GLO PEM and NASA CASA,which have been to be two major models.Finally,The NPP research in China are also introduced in the paper.
