Extended Land-Use Coding System and Its Application in Urban Brownfield Redevelopment: Case Study of Tiexi District in Shenyang, China

Management of land use related to brownfield redevelopment areas offers opportunities to respond to the challenges from rapid urbanization in China. This paper explores the mixed functions of land use in brownfield redevelopment by using the Tiexi District in Shenyang as a case study and extending the current national land-use coding system. Based on examination of the land-use statistics for the Tiexi District, the authors found that the current coding system is not suitable or precise enough for calculating the areas of land use or its mixed-function-based measurement in a way useful for scientific research and local policy-making. Thus, an extended coding system is proposed, and four examples (two residential communities, one commercial business facility, and one industrial cultural plaza) were selected for empirical study. The extended coding system supplies more-detailed information for understanding the land-use functions in brownfield redevelopment and provides a more-valid database for measuring the social, economic, and environmental implications of redevelopment of brownfield lands. Extended land-use categories also should benefit local decision-making regarding long-term sustainable development.
