摘　　要：针对目前基于WebGIS税务征管系统数据量大、地图加载速度慢、税务点显示不连贯等问题,利用Ajax模式设计并实现了一种基于Ajax的WebGIS税务系统.WebGIS税务系统采用Ajax异步调用GIS服务器的方式,在无需增加网络带宽和任何浏览器插件的情况下,能够在浏览器端对税务点进行准确实时的显示.实例表明,该方法能降低浏览器与服务器之间的通信量,加快地图的加载速度,使系统的性能得到显著提高.There exist such problems as large data amount, slow loading map and incoherent tax dots displaying in the current Tax Management System based on WebGIS. To solve those problems, the authors study on the typical architecture of the Tax Management System, and then design and implement a kind of WebGIS tax system based on the Ajax mode. This system adopts an asynchronous approach of Ajax to call GIS server. It can display tax dots accurately and timely in the end of the browser without increasing network bandwidth and any browser plug - in package. The testing result indicates that the methods proposed in the paper have reduced the communication amount between the browser and server, accelerated the loading speed of the map, and improved the system performance notably.
