摘要
针对当前林业资源管理决策系统中资源信息共享及对复杂用户权限的访问控制、角色分配、个性化定制等方面存在的不足,分析了WebGIS和Portal技术的特点,然后探讨了基于Portal、角色访问控制及WebGIS等技术的林业资源管理决策系统的体系结构、功能数据流程、系统角色控制实现及系统实现。该系统大大加强了系统的资源信息整合访问、安全访问控制,降低了管理开销及管理的复杂度,实现了系统资源的快速整合利用。
Aim at meeting the very need of information- sharing,complex access authorization for kinds of user and system interface customization for individual user in the current forestry resources management and decision- support system, it firstly analyzed the WebGIS and Portal techniques in this paper, then brought forward the forestry, of the system, data flow of function, and the realization of system role for controlling system users,all these were supported by the Portal, WebGIS and access authorization by role controlling. The system enhanced the access to information integration of system＇s resources, security access control greatly, reduced management overhead and management complexity, and achieve rapid integration the use of system resources.
