Development Strategy for Urban Agglomerations in Yangtze River Economic Belt Considering Environmental Carrying Capacity

Abstract

The Yangtze River Economic Belt is a vital ecological security barrier and the focus of China's economic development. Promoting the construction of urban agglomerations in the Yangtze River Basin is crucial for accelerating the development of the Yangtze River Economic Belt. The five urban agglomerations in the Yangtze River Economic Belt were used as the research objects; their environmental carrying capacities and the coupling relationship between these capacities and urban agglomeration development were explored. Based on the results, we categorized these urban agglomerations into three types: (1) mature-environmental overload type constituting the urban agglomeration in the Yangtze River Delta, (2) high-speed development-environmental overload type, comprising the urban agglomerations in Chengdu-Chongqing and the middle reaches of the Yangtze River, and (3) cultivation-environmental non-overload type that comprised the urban agglomerations in central Guizhou and central Yunnan. Herein, we propose strategic suggestions for the development of urban agglomerations in the Yangtze River Economic Belt considering the aspects of ecological space control, optimization of spatial land patterns, green development of urban agglomerations, and improvement of the human settlement environment. These aim to strengthen the guiding role of environmental carrying capacity in developing urban agglomerations and provide basic support for promoting high-quality development of the Yangtze River Economic Belt.

The impact of basin horizontal ecological compensation policies on carbon emissions: A case study of the Yangtze river economic Belt

“…In most eastern cities, a typical "three-two-one" industrial structure has been formed, while western cities tend to have a relatively higher proportion of secondary industry. Wang et al [ 27 ]applied a four-quadrant analysis method and discerned that cities such as Chengdu, Chongqing, and those located in the middle reaches of the Yangtze River are classified as environmentally overloaded cities. Among these, eastern Sichuan Province and Hubei Province face notable strains on atmospheric environmental carrying capacity.…”

“…The Yangtze River Delta has emerged as one of the three crucial strategic core urban agglomerations along the Yangtze River Economic Belt [ 34 ]. Zhejiang Province is situated at the southern end of the Yangtze River Delta, and its economy has developed rapidly.…”

Unraveling the Variation Pattern of Oncomelania hupensis in the Yangtze River Economic Belt Based on Spatiotemporal Analysis

“…As the largest developing country in the world, China is devoted to the economic development and has given high priority to the construction of the Yangtze River Economic Belt (YEB) [ 1 ]. The YEB involves 3 major regions and covers 1069 counties (cities, districts) in 9 provinces and 2 municipalities [ 2 ], with a total area of about 2,052,300 square kilometers, accounting for 21.4% of the national land area. Being an inland river economic belt with the largest scale and widest scope of influence in China, the construction and development of the YEB will inevitably drive the flow and exchange of population and resources, which may have profound impacts on the occurrence, transmission and distribution of diseases, especially infectious diseases [ 3 ].…”
