Evaluation on the efficiency of smart land use under rational urbanization: Case study of Tianjin, Chini

Abstract

With the accelerating industrialization and urbanization, the contradiction between urban development and land use in China has become increasingly prominent. Land use has interaction effect with urbanization development, economic standard, land use pattern and ecological environment, and so on. The problem that how to implement smart land use under the background of the rationality of urbanization, and to promote coordinated and coupling development of person-land-industry becomes the focus of academia and government. Smart growth is an inevitable choice for sustainable growth of China city with constraints of resources and environment. To be honest, it is very important to integration of this theory with the practice of China cities growth. Based on the proposal, this paper uses all kinds of researches of related low carbon city development for reference from domestic and international under the national new strategic choice of rational urbanization. At the same time, the paper takes Tianjin as a case based on the urban smart growth theory, and is directed against status quo of all counties land use, building evaluation index system for county territory land use from aspects of dimensions economic intensification, resource conservation, urban and rural coordination and environment protection. In addition, this paper adopts the aggregate model which classifies and then orders to evaluate the efficiency of land use and measures the land uses standard so as to provide the scientific reference for path selection of the smart land use as well as transformation and upgrading of urbanization. The research shows that: in the first place, there are regional differences among all Tianjin counties land use situation, and there is a certain degree of upside potential. Secondly, by adopting the aggregate model which classifies and then orders, this paper will reflect overall situation of all counties land use more intuitively and the contribution degree that every index made to the result of smart land use. Thirdly, it is significant to coordinate industrial location choice and urban system layout, and to promote the spatial relationship between industrialization and urbanization. Last but not least, the development of rational urbanization in the future should follow the differences and highlight the leading functions among cities, and actively promote the intensive urbanization, shunt type urbanization, ecological urbanization, as well as integration of urbanization, and other leading county urbanization patterns. In the end, the country could realize the efficient and intensive use of land resources, and promote the rational development of urbanization.
