| 摘 要： | 我国林业信息化建设现状和林业空间应用需求决定了我国林业GridGIS是资源异构、分布式协作、自适应管理的解决方案。合理的体系结构设计有助于GridGIS的实现。参照GridGIS的已有研究成果,从网络结构、层次模型、系统实现技术原则3个角度,设计了林业GridGIS的体系结构。对等式网络结构有助于解决跨网络、跨地域下分布式协作与系统自适应管理问题;4分层模型有助于降低系统设计复杂性,减少系统的耦合性;包括基于标准构建、复用中间件、SOA在内的技术原则,有助于系统的稳定、可扩展、可更新。应用实践表明,该体系结构能够满足林业空间网格的技术需求。

| Abstract: | It is determined by the situation of forest information construction and requirements of forest spatial application that forest GridGIS in China is a solution of heterogeneous resources,distributed cooperation and self-adaptive management.An implementation of GridGIS can benefit from its reasonable architecture.Based on existing results,the architecture of forest GridGIS was designed from three aspects including network structure,layer module and technique principle.Peer-to-peer network structure is helpful... |
