Research on Urban Land Suitability Evaluation Based on GIS—A Case Study of Xi'an City

Abstract

The evaluation of urban land suitability plays a crucial role in urban planning and land management. Taking Xi'an City as a case study, this research, based on ArcGIS software, conducted an in-depth study and evaluation of urban land suitability by comprehensively considering factors such as terrain, land use status, and DEM elevation data. By collecting and analyzing a large amount of spatial data, a set of urban land suitability evaluation models was established. With the functionality of ArcGIS software, spatial analysis and data processing were carried out to generate spatial distribution maps of urban land suitability. The research results indicate that land suitability is influenced by various factors, including terrain features, land use status, and elevation. Therefore, when formulating urban planning and land use policies, it is essential to consider these factors comprehensively to promote sustainable urban development and rational resource utilization. In future urban development, it is necessary to combine the influencing factors of urban land to develop more scientifically sound urban planning, aiming to achieve optimized spatial layout of cities and efficient resource utilization.
