Research on the current situation and countermeasures of low-carbon ecological urban development: a case study of Guangdong Province

Current global climate change, increasing energy depletion, and continuous environmental degradation have made it crucial to transform the economic development model into a low-carbon economy. Urban development, being one of the major sources of carbon emissions, has made low-carbon and ecological urban development an important topic on the international agenda. This article uses principal component analysis and the entropy weight method to quantitatively evaluate the development of low-carbon ecological cities in Guangdong Province from three aspects: economic and social factors, living environment, and resource and environmental factors. Based on the current situation, it proposes development strategies to provide references and guidance for further low-carbon ecological economic development in Guangdong Province. In the current world situation, with global climate warming, increasing energy depletion, and continuous environmental deterioration, the transformation of the economic development model into a low-carbon economy is of great significance. Urban development, being a major source of carbon emissions, makes low-carbon and ecological urban development an increasingly prominent topic in international societal development. This paper quantitatively evaluates the development of low-carbon and ecological cities in Guangdong Province using principal component analysis (PCA) and the entropy weight method. The results indicate that economic and social development plays a decisive role in the development of low-carbon cities. Strategies for development are proposed in response to the current situation, providing guidance and reference for further progress toward a low-carbon and ecological economy in Guangdong Province.
