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。
Environmental education resources remote and heterogeneous are the main factors to realize resource sharing. In view of the fact that environmental education resources are geographically linked, the sharing model based on geographic information service grids is an effective way to share environmental education resources under the current technological environment . With the framework of geographic information, this paper explores a new environmental education resource organization and management scheme, deeply studies on data integration scheme and indexing and caching strategy, and builds an environmental education resource grid service. The experimental results show that the system has faster Response speed, to meet the environmental education resources sharing needs, the use of cache technology can effectively improve system service performance.
