Research on the Optimization of Urban Land Use Planning Based on GIS——A Case Study of Zhangjiakou City
With the continuous advancement of urbanization,the optimization of urban land use plan-ning has become a key issue in ensuring sustainable development of cities.This study is based on Geographic Information System(GIS)technology and aims to explore how to use GIS tools to opti-mize urban land use planning.By collecting urban land use data,natural resource data,and popula-tion economic data,a spatial database for urban land use planning has been established.Combining a multi-objective optimization model,the optimization research of land use planning was carried out with the goal of maximizing land use efficiency,minimizing environmental impact,and meeting the needs of urban sustainable development.The results show that forest land,grassland and cul-tivated land are the main landscape types in Zhangjiakou City and the matrix of the whole study area.The number of artificial surface patches is the largest and most dispersed.The research re-sults can provide some reference for landscape pattern planning and land use in Zhangjiakou City.
