“Occupation-competition-regeneration” nexus among land uses in a Chinese city: Interactions and transformations

Abstract

Cities are implementing land regeneration to ease incongruities between the supply and demand of land resources. This paper introduces the Land Competition-Allocation Model (LCAM), a land redevelopment framework based on land development processes and land competition. The model is divided into a spontaneous development stage, competitive development stage and regenerative development stage according to features of land development in different periods. Using the urban area of Tangshan as a case study, we assess the fitness of different land types in the studied area at the patch scale during the spontaneous development stage to identify regenerative objects. The competitiveness of different land use types, which serve as regenerative foundations, are analyzed and quantified in the competitive development stage. Based on the above analysis, a sequence of land regeneration is determined in the regenerative development stage. Our case study shows the effectiveness of the proposed approach in demonstrating how land uses in the study area have transformed from fragmented, scattered and disordered into centralized, agglomerated and ordered through regeneration. This paper thus offers effective theoretical and practical guidance on ways for government officials and planners to implement land regeneration.
