摘　　要：湿地是陆地生态系统重要的碳库和氮库,气候变化显著影响了湿地中的植物和土壤微生物,改变了湿地生态系统的碳、氮循环过程,而且日趋增强的人类活动更加剧了这种变化。综述了湿地中地上和地下生物过程、地上与地下生物过程交互作用对气候变化的响应及其对土壤碳、氮循环的影响、气候变化与人类活动叠加对湿地植物和土壤营养物质可利用性的交互影响,指出了相关研究中存在的不足,展望了未来相关研究的趋势。Wetlands contain a large proportion of the carbon and nitrogen stored in terrestrial soil pool. Climate change significantly affects plant and soil microorganisms and changes carbon and nitrogen cycling process in the wetlands. These variations would be enlarged by the combined effects of climate change and human activities. In this research, the response of aboveground and underground biological processes in the wetlands to climate change and their coupling relationship, and their effects on the cycling of carbon and nitrogen in soil were summarized. Then the combined effects of climate change and human activities on the plants in the wetlands and availability of nutrient in soil were discussed. At last, several issues of the advancing researches were raised, and some suggestions were made for the future related researches.
