Abstract
Recently, with the rapid increase of urban population and industrial agglomeration, the price of construction land has increased, and construction land has become increasingly scarce. Therefore, how to improve the construction land use quality (CLUQ) becomes more and more important. The purpose of the study is to evaluate CLUQ in China’s major cities and to analyze the dominant obstacle factors for quality improvement in order to provide policy advice for construction land management. This study adapts the data from 2014 to 2016 and constructs the evaluation framework of CLUQ involving economic quality, social quality, and ecological quality of construction land to evaluate and analyze CLUQ with the synthetic evaluation model, coupling evaluation model, and obstacle diagnosis model (ECO model). This study shows that the synthetic CLUQ of 23 cities out of 36 major cities in China shows a general increasing state. The economic quality of 26 cities out of 36 major cities in China has increased, while the social and ecological quality of 20 out of 36 major cities in China has decreased. In terms of spatial characteristics, the synthetic quality in the east and southwest of China is relatively high; in terms of spatial trend, the synthetic quality in longitude increases from west to east, and it shows an inverted U-shaped state in latitude. Moreover, economic development is the main obstacle factor for the improvement of CLUQ in Hohhot, Lanzhou, Urumqi, and Changchun. Social development results in the CLUQ lagging in Beijing, Guiyang, Shanghai, Xining, and Chongqing. Ecological development has a negative impact in that of Harbin, Qingdao, and Wuhan. Furthermore. The improvement of CLUQ lies in the coupling and coordinated development of economic, social, and ecological quality. For those with a low coupling degree, the targeted suggestions are given for different types based on city’s quadrant distribution.
Highlights
Construction land plays an important space and function in urban production and life [1].Because of the growth of urban population and industrial agglomeration, the price of construction land increases rapidly, and urban construction land is scarcer [2]
To make the synthetic evaluation value of coupling degree and quality clearly displayed in the cartesian coordinate system, Z-score standardization is firstly carried out for the results of the coupling degree and quality evaluation value in the study, and the specific calculation process is shown in Formula (1)
This study focuses on an analysis of the quality evaluation, spatial analysis, and obstacle diagnosis of construction land use quality (CLUQ) in 36 major cities in China based on ECO model
Summary
Construction land plays an important space and function in urban production and life [1]. There have been many studies on agricultural land use quality evaluation, but the research on CLUQ is insufficient; evaluation framework of land use efficiency can provide reference for CLUQ. Yuan et al [12] set up the index system of land use efficiency from three aspects of economic, social, and ecological benefits, and calculated the land use efficiency of mining cities in Western China with the improved entropy method. The existing research pays less attention to the evaluation of CLUQ and mainly uses a single evaluation method, so it is of importance to focus on the construction of the evaluation framework of CLUQ and the application of synthetic model. Combined with quadrant chart analysis, we put forward differentiation construction land use policies, which can provide decision-making reference for improving the CLUQ in the Chinese major cities
