摘  要：
全球气候变化背景下生物地球化学循环的响应规律和陆地植物适应对策已受到广泛关注.本文在分析气候变暖和降水变化对不同生态系统植物C∶N∶P的影响、CO2浓度升高对不同光合途径物种元素的影响,以及氮沉降对土壤-植物元素影响的短期和长期效应等基础上,从植物生理特性和土壤有效营养元素变化等方面揭示了其可能存在的内在机理,以期为研究C、N、P化学元素在土壤-植物之间传递与调节机制、陆地生态系统结构和功能,以及生物地球化学元素循环对气候变化的响应提供理论依据.最后提出了该领域研究中存在的问题及对今后研究的展望.

摘  要：
The response patterns of biogeochemical cycle and the adaptation strategies of terrestrial plants under the background of global climate change have received extensive attention. This paper analyzed the effects of climate warming and precipitation change on the plant C: N: P in different ecosystems,the effects of elevated atmospheric CO2on the plant nutrients in different photosynthetic pathways,and the short-term and long-term effects of the responses of soil-plant nutrients to nitrogen deposition,and explored the possible underlying mechanisms in terms of the plant physiological properties in relation to soil available nutrients,which could provide theoretical bases for studying the nutrients( C,N and P) transmission and regulation mechanisms between soil and plant,the structure and function of terrestrial ecosystems,and the responses of biogeochemical cycle to global climate change. The existing problems and the further research directions in this study area were proposed.
