事故后果分析软件（ＰＨＡＳＴ）在天然气管道泄漏评价中的应用

遥感督察工作对于促进新型城镇化健康发展、城乡规划科学有序实施和依法行政具有重要意义。本文以宁波市为例，基于卫星遥感影像的光谱特征，利用多时相的遥感影像，采取人机交互的作业方式得到变化图斑，然后根据城乡规划资料赋予变化图斑相关属性，最后得到图斑数据库，凸显了卫星遥感影像应用于城市规划督察的优势和特点。

Application of Remote Sensing Image in Urban Planning Supervision of Ningbo

Remote sensing supervision is of great significance of promotion the healthy development of the new type of urbanization,Urban and rural planning scientific and orderly implementation and law-based administration. This paper based on spectral characteristics of satellite remote sensing image to extract the variation spots using multi-temporal satel-lite remote sensing images and human-computer interaction method. According the urban and rural planning data to re-trieve the information of the variation spots,then put them to the database. This paper highlights the advantages of satel-lite remote sensing image application in urban planning supervision.
