摘　　要：为了确保机场的飞行安全,以《民用机场飞行区技术标准》规章为依据,结合障碍物限制面的相关定义以及飞行区等级指标Ⅰ为4的障碍物限制面尺寸和坡度的要求,运用Auto CAD绘画出机场净空平面图形,将文件导入GIS系统,计算出各个障碍物限制面的许可高度,构建不同的障碍物限制面,建立民用机场三维净空模型,将障碍物图层与限制面图层进行叠加分析,对障碍物进行信息查询,可获得障碍物位于哪个限制面以及是否超过该限制面的许可范围。To ensure the flight safety of the airport,on the basis of the Technical Standards for Civil Airport Flight Areas,considering the relevant definition of the obstacle and the requirements for the size and slope of the obstacle limit surface where the flight zone grade index I is 4,Auto CAD was used to draw out the airport clearance plane graphics.The files were imported into the GIS system,the allowable height of each obstacle limit surface was calculated,different obstacle restriction surfaces was constructed,the 3 D clearance model of the civil airport was established.The obstacle layer with the restricted surface layer is superimposed to make information query on the obstacles,and get which limit surface the obstacle is located and whether the limit surface is exceeded.
