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。
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 to resolve distributed cooperation and self-adaptive management for cross networks and transregions.Module of four layers makes for a reduction of the complexity and coupling of the GridGIS.Technique principles which include standard construction,reusing middle ware and SOA,redound to the stabilization,extendibility and updatability of the GridGIS.It can be concluded from analyses and application that the architecture can meet the requirements of forest GridGIS.
