Abstract

Urban fragmentation affects sustainability through multiple impacts on economic, social, and environmental cost. Characterizing the dynamics of urban fragmentation in relation to economic transition should provide implications for sustainability. However, rather few efforts have been made in this issue. Using the case of Shanghai (China), this paper quantifies urban fragmentation in relation to economic transition. In particular, urban fragmentation is quantified by a time-series of remotely sensed images and a set of landscape metrics; and economic transition is described by a set of indicators from three aspects (globalization, decentralization, and marketization). Results show that urban fragmentation presents an increasing linear trend. Multivariate regression identifies positive linear correlation between urban fragmentation and economic transition. More specifically, the relative influence is different for the three components of economic transition. The relative influence of decentralization is stronger than that of globalization and marketization. The joint influences of decentralization and globalization are the strongest for urban fragmentation. The demonstrated methodology can be applicable to other places after making suitable adjustment of the economic transition indicators and fragmentation metrics. View Full-Text
