The invention relates to mobile communication network covering emulation interactive adjustment method based on GIS, and comprises the following procedures: a GIS geographical information system and a radio-wave transmission model are used for changing antenna parameter through emulation; the radio-wave transmission model is used for calculating the covering range; the space background property of the covering area obtained from an electric map is taken as the basic parameter, modifying factor and additional parameter and the like in the radio-wave transmission model, and the calculation result of the revised model meets the expected requirement; the covering edge is dragged in the electric map to meet the covering demand, the antenna parameter is extrapolated through the radio-wave transmission model, comprising suspending height, direction angle and inclination angle, etc, as an adjustment scheme, thereby realizing the real-time, the present-environment interactive emulation adjustment of the antenna parameter and the covering property. The method raises the precision and accuracy of emulation, saves great deal of on-site route exploration work and repeated adjustment work, allows covering planning and optimization to be more correct, and provides a firm basis for the plan, evaluation and optimization of network.
