摘　　要：针对现有WebGIS开发效率不高、并发能力不强及服务器负载过重的问题,利用MVC设计模式在.NET开发平台中,建立了一个实用的WebGIS应用系统模型,并在此基础上进行了仿真。系统对WebGIS的客户端、服务器端进行了计算机仿真。系统具有显示的直观性与逼真性,而且具有很强的扩展性,可用于与WebGIS有关的教学与科研、实验分析。典型仿真实例及结果表明用MVC设计模式仿真WebGIS系统是方便和高效的。Based on low efficiency of designing, low concurrency and high load of server of the current WebGIS field, this paper proposed a proper application model of WebGIS by using design pattern of MVC in. NET development platform. A simulation based on this model was also presented. The system simulated the client and server of WebGIS. The system had not only visual display and reality, but also strong expansibility, could be used in teaching and scientific research and experimentation analysis related to WebGIS. Several typical simulation examples and results show that it is convenient and effective using design pattern of MVC to simulate WehGIS system.
