【摘要】 以遥感技术和地理信息系统技术为基础,利用层次分析法对靖边至郑州段输油管线进行综合评价,建立了管道选线的综合评价体系。该体系包括线路长度、交通状况、穿越障碍、地形地貌等4个方面的12个因子,运用层次分析法结合专家知识,实现了全部因子的权重排序。以GIS为技术支撑,对各专题进行了空间分析和统计,建立管道选线综合评价模型,详细客观地评价了各备选线路,为管道选线决策提供依据。更多还原

【Abstract】 This paper describes the application of RS and GIS to the comprehensive evaluation in pipe-route selection between Jingbian and Zhengzhou, the most difficult section in the project of transmitting gases from western China to eastern China. Considering the characteristics of this area, the authors established a comprehensive evaluation system of the pipe route with RS as the basic information source. The system includes twelve data layers such as pipe length, traffic conditions, crossed barrier and terrain. Taking GIS as the technological support, the authors carried out spatial analysis and statistical analysis for each topic. By means of Analytic Hierarchy Process (AHP) combined with experts’ knowledge, administrative level analysis was used for all element weight defining and sequence arrangement. All routes were objectively evaluated in detail. The best route has been selected, which provides the decision basis for route-selection.更多还原
