This paper addresses some issues related to the carbon cycle and its utilization by society. Traditional uses for agriculture, forestry, as a source of fuel and other products, and for pastoral farming, among others, have recently been supplemented by identifying its potential for mitigating the increasing concentration of greenhouse gases in the atmosphere. Through the Kyoto Protocol, carbon has become a commodity and the CO(2)-absorbing capability of the vegetation and soils an economically valuable asset. The multi-facetted roles of the C cycle and its sensitivity to human activities present a demand for techniques that permit accurate, timely and affordable characterization of the various components of this cycle, especially on land where most human activities take place. Such techniques must satisfy a range of demands in terms of purpose, clients for the information, and biosphere properties. However, if successful, they offer the potential to support monitoring, reporting, policy setting, and management of terrestrial biospheric resources. The context for these requirements and possibilities is illustrated with reference to the China Carbon Sequestration Project and its findings.
本文探讨了一些与碳循环及其社会利用相关的问题。农业、林业、作为燃料和其他产品的来源以及畜牧业等传统用途，最近又通过确定其在减轻大气中温室气体浓度增加方面的潜力而得到补充。通过《京都议定书》，碳已成为一种商品，植被和土壤吸收二氧化碳的能力成为一种具有经济价值的资产。碳循环的多方面作用及其对人类活动的敏感性，对能够准确、及时且经济地描述该循环各个组成部分的技术提出了需求，特别是在大多数人类活动发生的陆地。此类技术必须在目的、信息客户和生物圈特性方面满足一系列要求。然而，如果取得成功，它们有可能支持对陆地生物圈资源的监测、报告、政策制定和管理。文中以中国碳封存项目及其研究结果为例，说明了这些要求和可能性的背景情况。
