全球变化下的我国北方草地研究进展与系统生态学思考

Progress in Grassland Ecosystem of North China under the Global Change and its Consideration Using System Ecology

北方草地在我国具有重要的生态经济地位。文章较为详尽地阐述了内蒙古草地生态系统碳循环的研究现状,包括植物、凋落物和土壤三大碳库,总结了人类活动和CO2浓度升高对草地碳循环的影响。针对缺乏系统科学的研究现状,以系统生态学的能值理论为出发点,文章探讨了我国北方草地生态系统的研究方向。

Grassland in North China is a very important eco-economic system.In this paper,the research of the carbon cycle in the grassland ecosystem in Inner Mongolia was systematically summarized,involving the plant,the litter fall and the soil carbon pool,as well as the effect of human activity and CO2 enrichment on carbon cycle in grassland ecosystem.Additionally,some unsettled issues of carbon cycle in grassland and the related key research emphasized in coming future were discussed.
