Abstract

Abstract. Rising CO 2 is predicted to impact global warming, and the city is the most important carbon source. Based on the theory of unban carbon sink , we surveyed the the most important carbon source and sink inffect factor, and take them as the constraint conditions of urban ecological space by calculating different kinds of carbon sink. Depended on the spatial analysis of GIS, we form the whole low-carbon network of the green city with the source of oxygen outside, greenbelt-greenheart inside and neighbor-greenland by the qualitative and quantitative analysis method. At the end, optimize the urban ecological spatial pattern in urban low carbon, which is conducive to help urban to become more perfect on planning and development.
