An evaluation framework for the sustainability of urban land use: A study of capital cities and municipalities in China

Abstract

The urban land use involves more severe sustainability challenges than agricultural land use. An effective approach for evaluating urban land use is essential for meeting this challenge to improve efficient land use management. This approach must fit into a coherent conceptual and analytical framework covering different aspects, including social, economic, environmental and rational land use structure. A major problem with this is the lack of the evaluation approach for objectively evaluating the sustainability of urban land use in practice. In this paper, an evaluation system for the sustainability of urban land use (ESULU) is presented aimed at rectifying this situation. This is based on 13 indicators drawn from previous literatures in consultation with a group of experts in this field. Principal Component Analysis (PCA) is applied to assist in identifying the major factors for evaluating the sustainability of urban land use. Examination of the results provides a grouping analysis of the capital cities and municipalities, indicating a general disproportion between coastal and interior urban cities in China. The findings lead to further suggestions and recommendations for central and local government to design relevant policy in achieving the sustainable development of urban land use and planning.
