随着人类对生物系统和大气化学影响范围的扩大，准确监测陆地生物圈的全球尺度变化已变得极为重要。例如，1997年的《京都议定书》标志着一些重大的社会经济和政治决定，这些决定可能涉及二氧化碳排放和全球碳循环影响。这些决定将在很大程度上依赖于对全球生物圈变化的准确测量（Schimel，1998年; IGBP TCWG，1998年）。一系列的国家和国际计划已经启动了全球卫星观测、碳和水通量的关键实地测量以及全球模型开发，以便开始监测生物圈。通过这些方案检测生态系统通量的年际变化和长期趋势，将能够及早表明基本的生物圈变化，否则这些变化在生物群落开始重大转变之前可能无法被发现。本文介绍了一个蓝图，更全面的协调各种通量测量和建模活动，成为一个全球陆地监测网络，将有直接关系到全球变化的政治决策。
Accurate monitoring of global scale changes in the terrestrial biosphere has become acutely important as the scope of human impacts on biological systems and atmospheric chemistry grows. For example, the Kyoto Protocol of 1997 signals some of the dramatic socioeconomic and political decisions that may lie ahead concerning CO2emissions and global carbon cycle impacts. These decisions will rely heavily on accurate measures of global biospheric changes (Schimel, 1998; IGBP TCWG, 1998). An array of national and international programs have inaugurated global satellite observations, critical field measurements of carbon and water fluxes, and global model development for the purposes of beginning to monitor the biosphere. The detection by these programs of interannual variability of ecosystem fluxes and of longer term trends will permit early indication of fundamental biospheric changes which might otherwise go undetected until major biome conversion begins. This article describes a blueprint for more comprehensive coordination of the various flux measurement and modeling activities into a global terrestrial monitoring network that will have direct relevance to the political decision making of global change.
