摘　　要：针对林业有害生物监测与预警系统建设中存在开发成本较高、开放性较差、灵活性较低等问题,提出基于开源GIS的系统架构。阐述以PostgreSQL/PostGIS为空间数据库、MapServer为GIS引擎、OpenLayers为客户端搭建据的系统平台,对多级地图缓存和基于Web Service的模型库等关键技术进行分析与描述。原型验证及工程实践结果表明,该系统具有低成本、高开放、扩展性强等特点,对于加强林业有害生物信息网络化管理和宏观科学决策具有推广应用价值。Due to the high cost,poor openness and low flexibility of previous GIS based monitoring and warning system for forest,an architecture based on open-source software was put forward.To build the system,PostgreSQL/PostGIS was used as spatial database,MapServer was used as GIS Engine and OpenLayers was used as client.Detailed analysis and description were carried out on multi-level map caching and model libraries building based on Web Service.The prototype verification and engineering practice show that the system,which has low cost,high openness and strong extensibility,is of great application value to strengthen the forest pest information network management and macro scientific decision.
