摘要
It is disputable that global large-scale urbanization and climate change has become an outstanding issue, which requires the common concern of mankind. However, it is not yet clear what is the complex relationship between urbanization and climate change and how to scientifically deal with climate change in the process of urbanization. Further exploration from science and management to practice are needed in order to achieve global and regional sustainable development. This paper first displayed the basic facts of mass urbanization and climate change and summarized interactions and possible mechanisms of urbanization and climate change. Urbanization leads to heat island effect, uneven precipitation distribution and extreme weather, together with local-regional-global multi-scale superposition effect, which aggravates global climate change. The impact of climate change on urbanization is mainly manifested in the aspects such as changes of energy consumption, mortality and the spread of infectious diseases, sea level rise, extreme weather damage to infrastructure and water shortage. This paper also briefly reviewed relevant international research and joint actions, and put forward an analysis framework of multidimensional sustainable urbanization adapting to and mitigating climate change, from the perspective of key dimensions of urbanization, namely, population, land use, economy and society. We call on to strengthen the interdisciplinary research of science and humanities, take urbanization and other human activities into consideration of the land - atmosphere system, and explore the human-land-atmosphere coupling process. The adaptation and mitigation from the perspective of human activities represented by urbanization might be the most critical and realistic way to deal with climate change.
