摘　　要：随着网络地图技术的发展和森林病虫害信息公开的要求,表现力丰富的病虫害空间分布网络专题地图需求日益强烈。针对以往构建WebGIS系统基于传统的HTML方式或改进的Ajax方式,导致开发烦琐、代码难以维护、开发成本高昂和表现力不足的问题。通过利用最新的Flash Flex RIA和Web Service技术,在Google Map API组件之上建立了具有多源数据整合、网络负载分离且具有良好用户体验的森林病虫害网络地图系统。并且详细介绍了系统的组织构架、技术流程、具体实现方法、跨域安全和密钥问题。实践表明,利用该方法构建表现力丰富的森林病虫害WebGIS系统是可行的和有效的,对于森林病虫害的预报与防治和病虫害信息公开提供了系统平台;同时,也对构建其他行业性WebGIS软件系统均有一定的参考价值和现实意义。Along with the development of web map technology and the demand of publicising forest pest information,there is increasingly strong need in expressive thematic web map in regard to spatial distribution of forest pests.In this paper,we build a forest pests web map system with multi-source data integration,web load separation and well user experience on Google Map API components by utilising the latest techniques of Flash Flex RIA and Web Service to solve the problems of tedious in development,hard in maintaining code,high development cost and weak in expressive capability caused by previous WebGIS system construction on the basis of traditional approaches of HTML or improved AJAX.At the same time,we expatiate on the framework,technical process,specific implementation approach,cross-domain security and encryption key issue of the web map system.Practices illustrate that it is feasible and effective to construct an expressive forest pests WebGIS system with the way described,it provides a system platform to the forecast and prevention of forest pests and the publicity of pests＇ information;meanwhile,it also has certain reference value and practical significance to constructing the WebGIS software system in other industries.
