摘要: 从一般计算型网格和数据型网格的概念和特性出发,结合森林资源与林业生态工程信息网格(数字林业网格)中数据的特点,提出一种森林资源与林业生态工程信息网格中空间处理服务实现的方法。通过讨论广域异构环境下构建森林资源与林业生态工程信息网格的原则和标准体系,给出森林资源与林业生态工程信息网格的体系结构,讨论矢量数据服务的网格注册、网格发现和网格传输,各种GIS服务的网格封装策略和实现方法以及构成森林资源与林业生态工程信息网格的任务调度问题。通过退耕还林工程潜力分析的应用来验证从核心基础网格扩展成森林资源与林业生态工程信息网格的可行性。

Abstract: Proceeding from the concepts and characteristics of the calculating type gird and datums type gird,and combining with the characteristces of datums in the forest resources and digital forestry grid,an implement method for spatial processing service in digital forestry gird(DFG) was put forward in this paper. The systematical structure of DFG was obtained through disscussing the principle and standard system of constructing DFG in the generalized isomerism environment. The gird registration,gird discovery,and gird transport of the vector data service,and the problems about gird encapsulation tactics and its implement method,as well as the task and regulation of composing DFG,were discussed especially. Finally,the application to analyzing the potential of the converting cropland to forest project had proved DFG to the teasible.
