論文概要: Taking cities in the Yangtze River Economic Belt (YREB) of China and cities in Japan as study areas, this study examines the carbon emission patterns and carbon emission mechanisms of growing and shrinking cities in the context of developing and developed countries and provides references for developing differentiated urban carbon emission reduction strategies.
Chapter 1 focused on the research background and purpose of the study. In this chapter, the challenges of climate change faced by cities in China and Japan are fully demonstrated.
Chapter 2 focused on a literature review of urban growth, shrinkage, and their environmental impacts. In this chapter, the impacts of urban development patterns and their link to carbon emissions are introduced.
Chapter 3 focused on research objects and analysis methods. This chapter provides a comprehensive description of research objects and methodology, which can make the research more logical.
Chapter 4 focused on identifying urban development patterns. In this chapter, the change rates of urban population and population density were examined to categorize urban development patterns into four types: growth, potential shrinkage, smart shrinkage, and continuous shrinkage.
Chapter 5 focused on carbon emissions in growing and shrinking cities. In this chapter, the scales and trends of carbon emissions were examined under different urban development patterns.
Chapters 6 and 7 focused on nonlinear effects and spatial effects of carbon emissions in growing and shrinking cities. In this chapter, detailed carbon emission influencing factors are quantified for growing and shrinking cities.
Chapter 8 summarizes the carbon emission mechanisms of growing and shrinking cities in China and Japan. The mitigating measures for carbon emissions in different cities are also presented.
Chapter 9 provides a concise summary of carbon emission patterns, trends, and influencing factors of growing and shrinking cities in China and Japan.
