英文摘要： This paper, concerning Beijng's construction of world low-carbon metropolis, which is in a microscopic scale as well as a new perspective of humanities - nature coupling process, takes Olympic Centre district of Beijing as the research case to build up a spatial model of key elements vertical flux with respect to carbon emission and high-precision carbon emission account by applying principles of Geography, Ecology, Environmental Science and Systematic Science, employing approaches of eddy covariance flux observation, remote sensing, GIS, material metabolism and building energy model, adopting the data of Quick-Bird image with resolution of 0.61m. Through building up a carbon emission model, which is based on 50 meters grid of buildings, traffic, population, vegetation and construction land, and stimulating carbon emission process, we hope to reveal the spatial-temporal dynamic variation principles of carbon emission respectively every month, quarter and year in case area from 2013 to 2015,and to explores impact mechanisms of typical humane factors on carbon emission , and explore the development models and fostering policy for low-carbon function area. This paper aims to, practically, solve the development problems of low-carbon function area, theoretically, reveal carbon emission variation principles of typica
