最短路径在乡村私立小学选址中的应用——以内黄县白条河私立小学选址为例

Shortest Path in Location of Village Private Primary School——A Case Study of Baitiaohe

地理信息系统以其强大的地理信息空间分析功能,对空间信息进行分析和处理,并在各种区域规划及选址项目中发挥着重要的作用。以内黄县白条河私立小学选址为例,运用最短路径选址方法,分析学校选址相关因素,综合考虑了人口的空间分布、周边学校现有数量、交通距离等,通过地理信息系统技术辅助进行了模拟分析,给出了学校选址的数学模型,通过实际模拟得出辐射区内的学生到学校的路径,制定出私立小学选址的最佳方案,最终确定办学位置。

Geographic Information System can analyze and process spatial information with its powerful GIS spatial analysis function , it also plays an increasingly important role in regional planning projects .This study takes allocation plan of the Baitiaohe private primary school as an example , and describes the data structure and algo-rithm for the shortest path issue , it focuses on the shortest path issue and solution algorithm with the shortest path school site location model , then combines with the actual data and works out the best plan for the location of the private primary school , finally determines the site to build the school .
