Suitable climate zoning is the precondition for realizing the low-carbon landscape. In this paper, combined with the indexes of WBGT and TS,typical climate parameters of typical sites in Sichuan were selected to quantify their climate comfort degree. According to the national thermal environment evaluation standards, the indexes for climate comfort zoning of Sichuan were proposed. As a result,five climate zones in Sichuan were divided, including cold-dry area, cold-wet area, hot-wet area of hot summer and warm winter,hot-wet area of hot summer and cold winter,and mild area. For different areas with differnet cliamtic charateristics,the sutiable seasons for outdoor activity were different,as well as the design strategies for low-carbon landscape.
