Study on the Urban Low-utility Land in the Context of China's Territorial Spatial Planning Reform: Taking Linyi City as an Example

Abstract

With the rapid development of urbanization, urban sprawl has resulted in the misuse of resources and the inefficiency of urban land use, so how cities can be of high quality is an urgent problem to be solved for the development of cities in various countries. Exploring the low-utility land remediation of land space is of great significance to optimize the pattern of land resource use and promote industrial upgrading. During decades of rapid urbanization, China has entered a period of stock development, and in the context of the reform of land spatial planning, the government pays more attention to the economic use of land optimization and upgrading, and the redevelopment of land space and comprehensive land remediation have also become an important part of the planning system at this stage. Linyi City, Shandong Province, has earlier carried out relevant research on low-utility land remediation, which represents the general status quo of the development of second and third-tier cities in China. Therefore, this study takes this city as an example, constructs a framework for the analysis of low-utility land, summarizes the overall characteristics of its national land spatial development, adopts the indicator construction method to evaluate the performance of the overall national land use of land space, and adopts the 'people-land correspondence' method based on the theory of the rural residential land to measure the potentials of the national land space, so as to provide a reference for the remediation of low-utility land.

The results show that:

(1) In the spatial development of the national territory, land for construction shows a 'circle + point' distribution pattern, with urban land for construction accounting for only 21.9 percent of its total size, and the proportion of land used for rural settlements and the distribution of the population are not coordinated.

(2) The development of land space in Linyi City varies greatly from place to place, with the average GDP of Mengyin County being only one-thirteenth of that of Lanshan District, at the same time, the urban and rural land use indexes for construction in Linyi City are upside down, which has far exceeded the requirements of the land rules and is facing a bottleneck in terms of resources.

(3) Territorial spatial development relies on incremental driving, with large-scale expansion of industrial land, the proportion of in situ urbanization in villages is high, with about 60 percent of rural migrant workers transferring for employment within the city, and the phenomenon of urban-rural amphibiousness is prevalent, which affects the effective utilization of rural construction land.

Key contributions to the findings:

(1)Formed a relatively complete process of low-utility land analysis, including 'development characteristics - causes - performance evaluation - potential calculation', which is of great significance for the preparation of the future system for the remediation of low-utility land in national land space.

(2) The preliminary proposal is that the main body, behavior, results, motivation, and internal elements together constitute the 'Subjective initiative + element function' type of governance ideas, which will provide ideas for the governance of low-utility land in other cities.
