摘　　要： 全球环境变化对土壤生态系统有机碳库的影响是当前研究的热点。本文综述了大气CO2浓度升高、温度上升、氮沉降等环境因素变化对土壤有机碳输入与土壤呼吸可能的影响,介绍了关于全球环境变化对土壤有机碳库影响的研究手段及其存在的问题,并就今后研究土壤有机碳对全球变化的响应提出了几点建议。 The effect of global environmental change on soil organic carbon pool has became a research hot point. In this paper, the possible effects of environmental factors such as elevated CO2 concentration in atmosphere, elevated air temperature and nitrogen deposition on soil organic carbon input and soil respiration are reviewed. And the means used for studying the effect of global environmental change on soil carbon pool, as well as their existing problems are also introduced. Sequentially suggestions on further research on response of soil organic carbon to global environmental change are proposed.
