Analysis of Meteorological Disaster Risk Zoning Based on Open GIS
Abstract：In recent years, meteorological disasters occur frequently, and pose a serious threat to the people＇ s live and economic development. Disaster risk zoning analysis as the basis of disaster prevention and mitigation work, is studied in our country. For exploring a technical method for county meteorological disaster risk zoning based on open GIS, this thesis first analyzes the development of open GIS, and ex- plores the quality, performance and the legal factors need to be noticed in the application of open GIS. Then, it takes Hekou of Dongying city as the experimental area, uses open GIS software such as QGIS, ILWIS, constructs various and total reasonable model for meteorological disaster risk assessment based on the regional disaster system theory, does the county regional meteorological disaster risk zoning analysis and completes the preparation of the experimental zone meteorological disaster risk zoning classification map.
