基于地理信息服务网格的环境教育资源共享研究

环境教育资源异地、异构特征是实现资源共享的主要因素,鉴于环境教育资源与地理位置的联系密不可分,基于地理信息服务网格的共享模式是当前技术环境下实现环境教育资源共享的有效途径。以地理信息为框架,探索了新型的环境教育资源组织和管理方案,对数据集成方案以及索引、缓存策略进行深入研究,并构建了环境教育资源网格服务,通过实验测试表明系统具有较快的响应速度,能够满足环境教育资源共享需求,利用缓存技术能够有效提升系统服务性能。

Research of Environment Resources Web Sharing System Based on Geographic Information Service Grid

Different Locations and heterogeneous characteristics of environment education resources is one of major factors. Con-sidering the inseparable relation between the environment education resource and geographic location, it is effective to enstablish sharing model which is used to realize the environment education resouce sharing based on geographic information service grid system. Based on frame of geographic information, one method of organizing and managing environment education resources was proposed, which includes data integration solutions, data index strategies, and cache policies. Based on this solution, a new type of environment education sharing system was realized and some experiment was conducted to test the performance of this system, the result shows that the responsing speed is acceptable and it can meet the needs of requirement of environment educa-tion sharing, and the cache policy can be used to improve the profermance of this system.
