摘　　要：针对当前国内已有空气质量预报系统在数值预报计算模式更新方面存在的弊端,提出基于Java RMI的数值 预报计算模式的构建方法,该计算模式具有易变性。通过分析两类传统方法在计算模式更新上存在的弊端,指出 Java RMI的远端对象调用机制在实现方法上的优越性。阐述基于Java RMI的新方法的实现,展示如何在集成该 处理模块的新系统中保证预报内容的准确性、及时性及其良好的可扩展性。Tradltionally, the realization of air quality numerical forecast pattern used in environment information systems only performed simple data transport between client and server computers,they usually appealed to such two methods： 1） Calculation program was loaded in client computer,after the client computer finished all the calculations, the results were uploaded to server,and the server was only used as database management tool. 2）All calculations were finished in server, the client computer was only used for browsing. The two methods were both not capable to renew the algorithm in good time. Toward this shortcoming, this paper initially put forward the method that builds air quality numerical forecast pattern based on Java RMI. The new method mainly had two outstanding advantages,one was the algorithm loaded in client computer could be renewed in good time,which ensured all results were exact absolutely, the other was the system had excellent extensibility,which guaranteed the system would be easy to update and maintain.
