Abstract


Groundwater is an important part of the terrestrial freshwater resources, groundwater to alleviate the problem of urban water plays a key regulatory role in urban water supply and demand have become increasingly prominent. At the same time, due to the lack of scientific management of groundwater exploitation, but also caused a number of environmental and geological problems. How to become a scientific and rational management of groundwater urgent need to address the real problem. Requirements of scientific management and analysis of data on groundwater resources, and summarized based on reasonable groundwater development and application of measures. Therefore, the urgent needs of the groundwater management departments to establish the the groundwater information analysis and management system. This thesis is based on GIS technology to the study of groundwater resources information management and analysis system theme solve the theoretical study the groundwater information analysis and management system based on GIS concepts and the overall structure of the data model, application model structure system and other issues; from technical methods to study and solve the problem of the establishment of a database, integrated the application model realization GIS environment, user interface design and implementation. This guidance, the paper is a comprehensive analysis of summed GIS analysis and research on the basis of the status quo in the the groundwater field of application, the composition and function of groundwater information management system based on GIS. Target regional groundwater information and space analysis, using a structured system design, system feasibility analysis, design principles based on the research objectives of the GIS groundwater information management and analysis system, and the system overall structure; in-depth study the control groundwater formation, occurrence and other factors based on the analysis as a precondition to service users and space, groundwater spatial database structure, spatial data layers divided and Element Properties data structure; from regional groundwater space analysis needs of , research, established by the spatial statistical analysis, groundwater calculation groundwater potential analysis and comprehensive evaluation of groundwater model constitutes spatial analysis model structure; system MapObjects2. 2 ADO VB application technology development mode, GIS platform analysis model seamless integration. The same time, the system also ARCIMS JSP SQLServer2000 WEBGIS technology system to achieve information sharing platform based on B / S structure of the groundwater. The system consists of the spatial database management five parts module model library management module, spatial analysis module, attribute database management module and web publishing module, information on groundwater resources in the same platform storage, management, retrieval, update, analysis and evaluation and other functions. Using groundwater information management and analysis system developed based groundwater information six provinces in western China, to complete the construction of the database, the groundwater quality evaluation, the groundwater amount of computing and resource evaluation and potential analysis, groundwater information network data sharing , and achieved satisfactory results. The establishment of the system, not only to improve the effectiveness of the the traditional groundwater Information Analysis and management of groundwater resources the dynamic evaluation platform exemplary run, has important theoretical and practical significance of to promote groundwater resources information management.
