Abstract: Studying the urban comprehensive carrying capacity of urban agglomeration of Guangxi Beibu Gulf Economic Zone can speed up its new urbanization process and promote the sustainable development of urban agglomerations, and provide decision-making reference for relevant departments. The population, resources and environment, social development, economic development carrying capacity index was selected to establish comprehensive evaluation index system of urban comprehensive carrying capacity of Guangxi Beibu Gulf Economic Zone, and the comprehensive evaluation was carried out by entropy method. The results showed that urban comprehensive carrying capacity of Guangxi Beibu Gulf Economic Zone were steadily increased, had a steady upward trend, with low level and grading phenomenon; The inter-annual variation trend and and the spatial difference of each factor of carrying capacity were obvious. It was proposed to optimize the overall urban carrying capacity structure as a whole, protect the resource environment and enhance scientific and technological innovation, and improve the urban comprehensive carrying capacity according to the different local constraints.

Key words: urban comprehensive carrying capacity, evaluation, spatio-temporal pattern, constraint factors, Guangxi Beibu Gulf Economic Zone
