Abstract
The high coupling coordination of urban land use benefits is a significant factor for urbanization and sustainable urban development. This study, based on the statistical data from 2002 to 2017 of Xiamen City, constructs an index system that includes social, economic, ecological, and environmental benefits by evaluating the overall coupling coordination degree of land use benefits, using the entropy weight method (EWM), the coupling coordination degree (CCD) model, and the dynamic coupling coordination degree (DCCD) model. The results show that the coupling degree of Xiamen City’s land use is relatively low, while showing a positive trend of development. In terms of the management of land use, the market should play a major role to achieve more efficient land use and promote industrial upgrading. The government should take responsibility for supplying infrastructure, perfecting related laws and regulations, intervening the land use according to the law of markets, and expanding the investment in education, as well as science and technology.
Highlights
According to the United Nations, approximately 70% of the population will be living in urban areas by 2050 [1]
By comparing the results from the coupling coordination degree (CCD) and dynamic coupling coordination degree (DCCD) models, we found that their outputs of the coupling coordination categories of Xiamen’s land use benefits were consistent, both indicating a relatively low level with some distance to the optimal
The reason is that the CCD model calculation is based on the benefit values of land use, which focuses more on static description; whereas the DCCD result is obtained by measuring and calculating the change rates of the land use benefits, which is more sensitive to the changes in land use benefits
Summary
According to the United Nations, approximately 70% of the population will be living in urban areas by 2050 [1]. New problems have resulted from the overly rapid urbanization, such as the deterioration in ecology, land degradation, human-land conflict, a decrease in overall urban land use benefits, and even the abandoning of arable land in the rural areas [3,4]. To this end, China has been strengthening land use management since the early 1990s, mainly protecting the arable land resources and limiting the growth of developed areas [5]. China’s land for construction is still increasing with the rapid urbanization [7]. How to strike a balance among land uses, i.e., expand the benefits of land use while achieving healthy development, is a difficult problem that exists in the process of China’s urbanization
