The study of urban building combinations is necessary to achieve sustainable urban development, as through such a study we can better grasp the process of urban development and evolution, guide the direction of future urban development, optimize the urban ecological environment, and improve urban livability. With the acceleration of China's urbanization process, the development and evolution of building combinations in China's urban areas are also gaining momentum. Therefore, it is of tremendous practical use to explore the laws related to mixed developments in urban areas to guide rational urban planning and the study of urban microclimates. The analysis is an important foundation for the development of urban landscapes and provides important scientific support for the optimization of the urban ecological environment and the improvement of livability levels. From the data on individual buildings in Guangzhou in 2017, this paper determined basic building combinations in the main urban area using two indexes for building height and building spacing, identified building combinations on a wider scale using a hot-spot analysis, and analyzed the spatial distribution of building combinations and the influence of macro and micro factors. Nine building combinations were identified on the basis of average height and spacing of building convergence surface. As the basic units, the nine basic types were further divided into different combinations to form complex and diverse three-dimensional representations of buildings in the main urban area. Building convergence surface with a scale of hundreds of meters constitute the basic unit of building combination in the main urban area, and are dominated by mixed land use types. The basic types, mainly composed of high-rise buildings, played an obvious role in indicating land use with differences in combinations of each functional area. The basic types of main urban areas have prominent circle differentiation, but the laws for the different types differ. Land price was the core constraining factor for the decrease in urban building height and population density from the urban center to the periphery, as well as the background factor related to differences in urban building combinations. The influence of green spaces, the Pearl River, and the main road on the type, height, and density of the building combination at a micro level complicated building combinations.

Key words: building combinations, height, spacing, circle distribution, land price, Guangzhou
