摘　　要：随着Web技术与GIS技术的迅猛发展,设计开发基于WebGIS的大型防汛指挥信息服务系统已变为可行与必须。结合黑龙江省防汛指挥信息服务子系统的设计开发实际,研究使用基于B/S体系的ArcIMS作为WebGIS的解决方案;研究解决应用ArcIMS中的几个关键技术问题:以正向与反向信息查询为例,研究设计信息查询的数据流程;为便于空间数据的管理与应用,研究图层的划分与组织方法;为达到经济与实用的目的,研究不同比例尺地图的无视觉差切换;为按用户要求表现地图,研究如何编写地图配置文件。还给出了这些关键技术在实际设计开发中的应用效果。With the rapid development of the Web and GIS technologies, it has been feasible and necessary to design a goodsized flood control and command information service system Nearly associated with the practice of the Heilongjiang Province flood control and command information service subsystem, the Web GIS's solution based on the ArcIMS is researched in this paper, and the several key techniques of applying the ArcIMS are studied The techniques are as follows: (1) Taking the obverse and the reversal information queries as examples, the data flow of the information query is researched and designed; (2)For the convenience of managing and using the spatial data, the method for dividing and organizing the map layers is studied; (3)For the economical and practical purpose of system, the switch between the different scale maps without sight equation is researched; and (4)According to the user's demand to display the map, how to write the map configuration file is discussed The effect of these key techniques, which are applied to the practical design and development, is also illustrated
