Study On Regional Impact Analysis Method Of Agricultural Natural Disaster Based On GIS

Based on several years of provincial and country agricultural economic data, this paper providescomprehensive application of GIS, data base, regional economic analysis method, computer modelingas well as agricultural disaster treatment and analysis method to carry out research on regional impactand analysis of agricultural nature disaster. In this research we studied GIS-based agricultural regionalimpact analysis theory, developed an automatic generating tool of analysis report. In view of frequentlynature disaster and agricultural emergency, we choosed drought, floods, typhoon and other naturedisaster as study objects, and proposed disaster project analysis method and fast disaster responsemethod. At the same time, we developed a decision support system for work needs of ministry ofagriculture. In this paper, results are follows:(1) This paper proposed method of agricultural regional economic impact analysis. GIS technology andspatial statistical analysis method was used for dividing agricultural industry regions into four typesas well as focusing on space gather characteristics of distribution patterns. Custom thematic mapmodule was developed for thematic map automatic generation for any regional economic impactindex, which enhanced visual display capability of agricultural economic impact result.(2) This study analyzed characteristics and types of agricultural nature disasters, proposed an agriculturaldisaster management framework and a rapid analysis method.(3) Proposing regional impact analysis of agricultural nature disaster. This paper provided thoroughresearch to some nature disasters which had high agricultural hazard and frequency of occurrence.According to regional disaster background, disaster features and crop production status, agriculturaldisaster analysis and forecast model as well as agricultural disaster regional impact analysis modelwere developed. In case of Jilin province disaster, the method and models were used for analyzingcrop disaster effect.(4) Proposing the method of automatically generating analysis report. Based on the method this paperdeveloped a tool of automatically generating analysis report, which can automatically generatedifferent disaster analysis report, dynamic data analysis results and regional economic impactanalysis. The tool of automatically generating analysis report has good versatility, practicalapplicability, high augment ability and friendly human machine interface. Different regions,agricultural economic indexes, nature disasters and emergencies are used for automaticallygenerating analysis report.(5) Designing and developing decision support system of agricultural nature disaster regional impactanalysis. The DSS realized rapid agricultural spatial-temporal information processing and analysis,agricultural nature disaster and emergency subject analysis, market price impact analysis and regionalimpact analysis of agricultural nature disaster.
