Abstract: Tideland resource is an important natural resource and also environmental resource and economic resource. To grasp accurately the present situation and dynamic changes of tideland resource, a three-dimensional management information system for tideland resource was developed based on the platforms of SuperMap and Skyline. The system has functions of managing tide resources reclamation and reclamation projects, analyzing spatio-temporal changes of resource and tideland evolution. Application shows this system could provide information support for the sustainable utilization and decision support for the planning and exploitation of tideland resources.

Key words: tideland resources, reclamation project, spatio-temporal changes, evolution analysis, Skyline, 3D management information system
