Paper Abstract

The study develops a new comprehensive evaluation model of urban construction land suitability by summing up the shortcomings of traditional GIS-based evaluation methods. The improved GIS-based model includes spatial suitability and non-spatial suitability, corresponding to spatial factors and non-spatial factors respectively. Using the analytic hierarchy process method and ranking method, the weights of evaluation indexes are decided. Using the spatial overlay analysis of GIS step by step, the final values of suitability levels can be obtained based on the new comprehensive evaluation model. Then, the paper takes Shijiazhuang city as an example to make the empirical study supported by ArcGIS9.2 platform. The construction land suitability levels in Shijiazhuang city are divided into four grades. The evaluation results reflect the actual situation in Shijiazhuang city. It will provide a scientific basis for urban construction land use planning and management. The study results show that the new model can overcome the shortcomings of traditional GIS-based methods and improve the assessment accuracy and operability. It reflects that the new model built in this study can provide a new idea and method for urban construction land suitability evaluation.
