摘　　要：文中主要从植被动态研究、植物水分利用效率研究、树木年轮的δ1 3C值对环境变化预测的研究以及利用1 3C标记应用于碳循环的研究几方面,阐述了稳定碳同位素分析在全球气候变化研究中的应用。Human activities caused a rapid increase in the concentrations of the greenhouse gases in the past century which led to an increased reflection of radiation, causing higher temperatures on the earth's surface. Studying on the terrestrial carbon cycling became the focus of environmental and ecological researches with the climate changing. Among the new study approaches the stable carbon isotope analysis are widely used in studies of the global carbon cycling.In this paper, the application of stable carbon isotope technique on vegetation dynamics, water use efficiency of plants, 13 C values in tree-rings as well as carbon allocation and fluxes were described.
