With the development of urbanization, the underlying land surface of urban areas also changes. The greatly declined natural landscape and increased number of buildings have significance influence on the urban climate and environment. Urban Climatic Map, a tool and platform for analyzing and evaluating the situation of urban climate, expands the application of urban climate information in urban planning and development. Based on the current situation in southern China for urban climate research, this study examined the difference of environment climate influence level caused by different factors. Combined with the existing compilation method of Urban Climatic Map, Guangzhou City was selected as the study area because of its typical subtropical monsoon climate characteristics. A complex underlying surface urban climatic map system was constructed with multiple environmental factors, assessment periods, and technical methods. Several technical means, including numerical model simulation, remote-sensing inversion, and spatial analysis in GIS, were comprehensively applied to evaluation urban air pollution, thermal load, and ventilation potential in Guangzhou City. We also put forward some preliminary planning recommendations. The results indicate that air pollution and thermal load are characterized by significant differences in seasonal and spatial distribution, while ventilation potential shows a clear difference in space and slight seasonal change. Guangzhou City is subsequently divided into seven zones and a spatial pattern of "superior north and inferior south" is observed. Specifically, the optimum types are mainly distributed in the woodlands and intercity cultivated land in the northern mountainous areas, and the most degraded types are located in the urban core areas of Tianhe, Yuexiu, and Liwan Districts, as well as the industrial areas in Baiyun and Zengcheng Districts. Finally, based on the results of environmental climatic analysis, planning measures of each climatic type are suggested to provide some scientific advices and direction for the sustainable development of Guangzhou City.
