Abstract: The land use/cover change and energy consumption caused by human activities not only have affected the carbon emission process,but also is a hot topic in the regional sustainable development.Based on the research of carbon emission evaluation methods, this paper applied the two methods-one was material balance algorithm which was aimed to calculate carbon emissions caused by human respiratory and fossil energy consumption, and the other was vegetation biomass method to calculate carbon fixation of the regional terrestrial ecosystem-to comprehensively estimate regional carbon balance.Upon the above analysis,the paper studied the balance of carbon budget in the Yangtze River Delta and the spatial differentiation of the balance ability in this region.Since 1995,the carbon budget of core areas in the Yangtze River Delta has become increasingly unbalanced with the increase of human intervention and decline of land vegetation.Those processes emerged in the region along the Shanghai-Nanjing line and other core cities,indicating that the terrestrial ecosystem cannot keep a balance by depending on itself.Moreover,policy suggestions to improve the balance of carbon budget were provided from the perspective of industrial transformation,land use patterns,spatial governance,etc.

Key words: carbon budget balance, spatial differentiation, terrestrial ecological ecosystem, Yangtze River Delta
