Land Reserve Potential Evaluation Based on GIS and Big Data Analysis: A Case Study of Nansha District, Guangzhou, China

As construction land is in shortage in first-tier cities of China, demand for inventory development and planning is growing at an alarming rate. Analyzing and evaluating land reserve potential is more important than ever to guide the rational use of urban land more scientifically. In this paper, the land reserve potential evaluation index system was explored, which was applied to the analytic hierarchy process (AHP) and based on network open-source databases. Focusing on commercial land, the analysis and evaluation model was carried out based on GIS, which was a step-by-step model to assess the commercial land storage potential and revised by the urban expansion intensity. The modeling result was validated by the people gathering center with OD data. This model was applied to a case study of Nansha District, Guangzhou, and a reliable analysis was conducted, assessing inventory and increment reserve units for commercial land use. Findings indicated that the approach significantly helped the orderly implementation of long-term urban renewal and rational development of new construction sites.
