Development of Groundwater Resources Management System Based on GIS in Poyang Lake Catchment

With the groundwater resources management in Poyang Lake catchment as an example, groundwater resources management system based on geographic information system (GIS)-MapInfo software was development using Matlab software, and visual basic language in this paper, and the main functions were also introduced. The user interface was developed using visual basic language, which can provide the running background work environment of MapInfo. Matlab was used to accomplish numerical calculation. The MapInfo's functions of spatial analysis and display were used in this system by visual basic program activating MapInfo. Many functions could be accomplished including the spatial and attribute data displaying, editing and querying, spatial statistics and analysis, thematic map compiling, and groundwater quality visual evaluation. Groundwater resources effective management and groundwater quality visual evaluation could be realized by development of this system. The development of this system will provide assistant decision supports for reasonable exploiting groundwater resources in Poyang lake catchment.
