Abstract:

Based on the meteorological and urban socio-economic data from 2000 to 2017, a comprehensive function of urban climate carrying capacity was constructed to evaluate objectively and quantitatively the variation of climate carrying capacity of Baise city, a mountainous city in Western Guangxi. The function consists of four evaluation indexes, namely, climate natural capacity, extreme climate event, urban climate pressure, and urban coordinated ability. The results show that since the 21st century, the overall climate carrying capacity of Baise city has shown an increasing trend with fluctuation, which reflecting an enhanced coordination ability between urban construction and climate, and there is still a large climate carrying space for urban construction. Climate carrying capacity is sensitive to extreme climate events, especially extreme drought. Human impact factors have important influences on climate carrying capacity. Improving climate carrying capacity and coping with climate change should improve the ability to defend against natural disasters and the ability of urban coordinated development, as well as reducing urban climate pressure so that a sustainable urban climate ecosystem in Baise city can be built.

Key words: Climate carrying capacity, Quantitative assessment, Climate-adapted city
