摘    要:草地生态系统的碳循环是维系陆地生态系统的基本机制之一,并与陆地生态系统的维持、发展和稳定性机制等相联系.通过对草地植物碳库、草地凋落物碳库、草地土壤碳库等草地生态系统碳循环的研究动态进行综述,旨在把握草地生态系统碳循环的特征及规律,从而深入研究碳元素各个贮存库间的定量迁移和转化关系的内部机制.

关 键 词:碳循环  草地农业生态系统  研究动态

Abstract:Grassland agroecosystem has played an important role in global carbon cycle, which is one of the basic mechanisms of the terrestrial ecosystem carbon cycle and associates with the maintain, development and stability of eco-environment. Review of the research progress and trend in the carbon cycle in grassland agroecosystem is meaningful to carbon cycle of terrestrial ecosystem even to global change research. The grassland carbon cycle in China is still at beginning stage, migration quantity and transforming mechanism of carbon between the plant, the litter and the soil carbon pool are short of integrated research. In this paper some comments on scientific uncertainties and methodologies are put forward to the study of carbon cycling in grassland agroecosystem.
Keywords:Carbon cycle  grassland agroecosystem  research progress and trend
