Abstract: Territorial space is the fundamental carrier carrying the distribution of various carbon sinks and carbon emission factors. Therefore carbon sinks increase and emission reduction of territorial space is the core point to realize that in various fields at the spatial level. Taking Pingle Ecological Conservation Development Area in Qionglai City, Chengdu City, Sichuan Province as an example, this paper studies the identification and influencing factors of carbon sink source and emission source in the whole area, and research the influencing factors. The results show that, the carbon sink capacity of ecological space can be strengthened by improving the scale contiguity degree and ecological species diversity, the internal balance between agricultural spatial carbon emission and carbon sink can be promoted by improving the quality of cultivated land and optimizing planting patterns, and the carbon emission capacity of urban space can be reduced by improving the land intensity and use efficiency. On this basis, the optimization and regulation strategies of territorial spatial pattern are formulated, in order to provide technical logic, method application, research results and other references for related research and practice.
