Abstract: Regional planning methods has long been a research hotspot, especially in the fields of landscape planning, resource management and spatial planning. Moreover, existing planning methods lack the basis for judging the pros and cons of planning results. In order to solve this problem, this research proposes a regional planning method (hereinafter referred to as “the Method”) based on the Geodesign Framework and the evaluation system for UN 2030 Sustainable Development Goals (SDGs). In this research, several mobile devices and the Geographic Information Systems (GIS) are adopted as tools for data acquisition, data management, analysis and visualization, and Yaohu Island in Nanchang City is taken as an example for empirical study of the Method. The research puts forward a model indicating the status of achievement (hereinafter referred to as “Model T”) based on SDGs evaluation indicators for the first time, to give full play to the iterative optimization role of Geodesign Framework in regional planning by calculating the cumulative score of different planning schemes by virtue of the evaluation matrix table for quantitatively judging the pros and cons of different planning schemes in achieving SDGs. Marking the initial application of the Method in Chinese regional planning, this research can provide a reference for theoretical research and practice regarding regional planning in China.
