【摘要】 本文通过对建设用地资源潜力评价体系的研究,建立了适用于北京市的建设用地资源潜力评价体系:制定了"先筛选,后评价"的建设用地评价思路和工作流程。建立了可利用建设用地筛选模型;在理论构建的基础上,综合利用GIS技术,开发建立了北京市土地资源和建设用地综合决策分析平台。研究发现只有保障了空间数据质量,可利用建设用地资源潜力评价的准确性和可持续性才能得到根本保证。更多还原

【Abstract】 In this paper,based on the research in evaluation system of the potential construction land resources,the potential evaluation system for construction land resources in Beijing was established.The evaluation ideas and workflow of "first filtering then evaluating" for construction land were developed a model that filtering the usable construction land resources was provided;at the same time,the integrated decision analysis platform of urban construction land resources in Beijing was developed based on the comprehensive theory and GIS technology.It has been integrated the spatial data include basic geographic information data,planning data,cadastral data and others 48 layer nearly 200G.And it can be use of for construction land resources automatic filtering,dynamic maintenance,statistical analysis,query and project site.Research indicated that the accuracy and sustainability of potential evaluation of available construction land resource could be guaranteed only depending on the quality of spatial data.更多还原
