Optimization of the Layout in Land Redevelopment Based on the Comparative Advantage Perspective

In highly urbanized areas, urban redevelopment is required to achieve both ecological and economic goals. However, how to balance the layout between built-up and ecological land is one of many challenges facing urban planners. Recent studies have proposed effective decision-making models based on ecology-economy comparative advantages (EECA), but these have not been applied to planning the redevelopment of urban land at the site level. Using the urban district of Zhanjiang as a research case, this study established a region-site dual-level model from the EECA perspective to optimize the layout between ecological and built-up land in land redevelopment planning. The findings indicated that better optimization results were obtained from the EECA perspective than ecological or economic suitability evaluations, which are often used in urban planning. This study is an extension of existing research on the optimization of different land-use type layouts, which will serve as a foundation for planners to obtain a basic understanding of the optimal land-use layout in land redevelopment based on EECA and evaluate regional development goals from the perspective of land resource redevelopment.
