This chapter focuses on the spatial carrying capacity of different types of space units. Based on the characteristics of different units, it discusses how resource carrying capacity, environmental carrying capacity, ecological carrying capacity, and infrastructure carrying capacity together affect the spatial carrying capacity and allocation efficiency of space units. Cities need agglomeration of economic and demographic elements to expand the scale of spatial carrying capacity. Basins need to allocate water resources rationally under the condition of limited water resources for the sustainable development of river basin ecosystem. Regions need to explore regional comparative advantages and transformation paths from regional industries. The case studies discuss how the spatial carrying capacity of cities, river basins, and regional transformation adapt to environmental changes and the direction of carrying capacity improvement.

This chapter takes three megalopolises including Guangdong-Hong Kong-Macao, Yangtze River Delta and Beijing-Tianjin-Hebei as research objects, firstly analyzes the connection relationship and megalopolis vulnerability among core cities in the context of regional integration. Secondly, we calculate there megalopolises to obtain the vulnerability of each city in 2018 Sex index. The results show that the central cities and economically underdeveloped cities of the three megalopolises are relatively vulnerable areas in the urban agglomerations, and areas have low sensitivity and high response. Finally, policy suggestions for megalopolis are given to improve the adaptive capacity of tackling climate change. The innovation of this chapter is to use spatial data to comprehensively evaluate and analyze the vulnerability, and to realize visualization in the map, which better reflects the distribution law and proposes a response to megalopolis vulnerability.
