地理信息系统在大城市城区供电规划中的应用

Application of GIS in Power Planning in Large Cities

近年来，国内大城市里旧区更新与再开发过程中，供电不足的现象相当突出．常规的城市供电规划方法因存在一定的局限性而较难适应这一局面．本文作者提出了应用地理信息系统（GIS）技术改进城市供电规划的设想，并以土地使用和变电站（所）的容量及位置关系为主线，开展了实验性的研究工作，其结果显示出GIS在计算精确性，评价结果直观性，方案调整灵活性等方面的优势，可将此方法作为城市供电规划、土地使用规划的辅助工具。

Lacking of power supply is one of main problems in urban renewal and redevelopment in Large Cities in China. This paper points out the ideas of how to use GIS' technology to promote the recent urban power planning. Some experimental work has been done on the relationship between land use and the location of transformer substations. The results of this research show the effective function, evaluation and adjusting plans of GIS.
