Abstract: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 agricultural resources management and decision support system at county scale, this paper firstly analyzed the portal and WebGIS techniques, then brought forward the architecture 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. Results show that the system strengthened the safe interview control of the system consumedly, the fast integration that carried out the system resources make use of.
Keywords:agricultural resources  portal  WebGIS  role control
