摘要

The urban development strategy of growth supremacism over the past 30 years in China has triggered a series of societal, economic, and environmental ecosystem problems. Urban development boundaries (UDBs) promoted by the Chinese government are the key for curbing urban sprawl and ending growth supremacism. Using a case study of Sanshui, this paper explores the integrated urban expansion resistance evaluation framework and constructs an index system with aspects of ecological, productive, and construction resistance. An improved minimum cumulative resistance model (MCRM) that introduced expansion capacity and expansion barriers was used to generate the minimum cumulative resistance plane. UDBs of different scale scenarios were extracted based on the generated resistance plane. The results showed that the minimum cumulative resistance surface generated by the evaluation framework and the improved MCRM comprehensively reflects the urban expansion resistance and indicates the spatial trends in urban expansion. Therefore, this article provides an effective approach for the delimitation of UDBs and compensates for the inadequacies of most prior research that ignored productive resistance, construction resistance, and expansion barriers. The simulation methods can be used to guide sustainable urban planning and comprehensively reflect the protection requirements of farmland and ecology. (C) 2017 American Society of Civil Engineers.
