摘　　要：探讨了城市规划建设中不容忽视的微波传输通道的保护问题,在理论上推导了障碍物顶点的允许高程,提出了利用Google Earth建立微波通道保护地理信息系统的构想,并以厦门西姑岭微波站和狐尾山电视发射台为例,具体介绍了两站间微波通道保护地理信息数据库的构建,为城市规划建设提供了可靠的技术依据。In this paper, the problem of protecting microwave radio link is discussed, and the maximum vertical height of obstacles is illustrated theoretically. Based on the practice of constructing database between Xiamen Xiguling Microwave Station and Huweishan TV Transmitting Station,a new conception of using Google Earth to establish GIS （Geographic Information System） is presented,and it provides a reliable basis for city construction planning.
