摘要
为降低可达性度量的实现难度,弥补现有GIS软件没有集成可达性分析模型或方法的不足,在详尽分析有关模型或方法与GIS集成研究现状的基础上,提出以改进潜能模型作度量模型,按GIS内部集成方式,使用面向ArcGIS 10的Python脚本编程技术集成开发可达性分析工具的设想,对可达性潜能模型分析原理、工具开发环境配置、使用数据的预处理要求、工具的具体设计流程和实现方法等作了详细叙述。最后以评价某市小学教育资源空间布局合理性为例,阐述工具在实际应用中应采取的使用方法和流程,实例评价结果验证工具开发的有效性。
In order to reduce the difficulty of accessibility measurement and make up for the shortcomings of existing GIS software not integrated with accessibility analysis model or method,based on a detailed analysis on the present research situation of models or methods and GIS integration,this paper proposes to develop an accessibility potential model analysis tool by using the python scripting for ArcGIS 10 and the GIS internal integration method.And then,it gives an detailed account of the development environment configuration,requirements of data preprocessing,design process and implementation method of this tool.Finally,the practical application method of this tool is described by an example of a spatial layout rationality evaluation on urban primary education resources,and the evaluation results demonstrate the effectiveness of tool development.
