Research & Development Of Regional Geological Hazards Information Management System Based On GIS

"The management system of regional geological hazards information based on GIS"is a professional geological information system which achieved the geological hazardsamount of sea data saving, space analysis and evaluation, information management. Itis under the pecuniary aid of the program of "The regional geological hazards survey& division of LaiZhou city, ShanDong province", which was actualized by the Chinesegeological environment monitoring center. Having already had the investigation,analysis and validating in field, making use of the GIS technique, taking the space dataas main material, The system carried out a data toward the conversion of information.This system is not only have theories meaning, but also have important realisticmeaning to estimate toward the regional geological hazards, forecast and prevention.The thesis aims at the concrete request and target with regional geological hazardsinformation management, analyzing the system need, elaborating the establishmentmethod of The management system of regional geological hazards information basedon the COM technique. We had built up the exterior attribute database with the Accessand developed the system customer interface under the environment of Visual Basicadopted MapObjects control, carried on a total design to the system database, structureand the main function mold in the meantime.On the basis of studying the regulation of slopes, landslides, debris flows, groundsites, cracks geological hazards which taking place in the district, we had researchedand developed regional geological hazards information management system. We hadfinished a geological hazards points distribute layer, administrative area layer, thetransportation layer, water fasten layer and the geological boundary etc. we had builtup the debris flows geological hazards exterior attribute database and the spacedatabase of five hazards. The system provide an alternant comprehensive analysis andhandle function in the distribute of space characteristic according to the geologicalhazards information, carry out management, prevent and cure, early warning ofregional geological hazards information.
