Natural disaster is one of the most important global isuue problems we are facing, especially tropical cyclone disaster, with its high frequency and intensity, is the most serious one among them. The socioeconomic development, the urbanization, the high concentration of property values and the density of population make the city to be more vulnerability and to face more threat to China.China located in the northwestern Pacific, is one of the most severely affected countries by typhoons. The eastern coastal areas are the most severely affected areas by typhoons that these parts of China are very important to Chinese economic development. It is recognized that if a tropical cyclone in the occurrence of such a disaster before the disaster risk accurately forecast the time of the disaster in real-time disaster monitoring, disaster of disasters accurate assessment of losses, It's able to carry out more effective disaster mitigation, disaster, disaster relief work, to reduce losses caused by disasters and reduce casualties, and reduce the possibility of secondary disasters.Typhoon by temperature, humidity, geography and other factors, caused by the typhoon disaster areas with loss of the natural environment and economic environment is closely related to the typhoon disaster assessment is therefore of the typhoon wind speed, rainfall, central pressure, such as typhoon path Typhoon targets and means of regional socio-economic environment of the natural environment and comprehensive evaluation of the study the risk of typhoon disasters extent.Multiple natural disasters our country has the characteristics and severity, and social and economic development is closely related to the situation. Based on the model of typhoon disaster assessment study of choice Supresoft broad assessment of a simple model calculation of China's typhoon disaster risk assessment. Typhoon disaster risk assessment is the hazard from the typhoon disaster pregnancy factor and an environmental point of view, analysis of natural disasters led to the phenomenon of the frequency and intensity of disasters, the establishment and preservation of historical records, drawing on the risk of typhoon disaster zoning map of vulnerability and estimate the potential impact.Based on the disasters of various factors on the formation of building a model of disaster assessment and establish the evaluation index system of disaster, on the basis of the typhoon disaster in China to carry out comprehensive risk assessment and zoning division of disaster and then discuss the disaster response and risk management measures . Major ones are as follows:1,To establish the path of the typhoon, the typhoon characteristics, disaster databases, in order to conduct risk analysis of typhoon disasters, through the landing of our data analysis typhoon affected areas in China and analysis of China's typhoon fabric of space-time laws vary.2, From a system point of view of the typhoon disaster brought the relationship between various factors and to study the typhoon disaster assessment model of selected Supresoft broad assessment of a simple model calculation for disaster assessment.3, Construction of a typhoon disaster evaluation system, making the typhoon disaster losses indicators in a unified dimensionless system is converted to the loss index as a basis for China's typhoon disaster loss assessment of the situation.4, The use of component-based development technology, application platform ArcEngine components in VS2005 using C# for the second development to achieve the appropriate statistical analysis, data, editorial management, buffer analysis function, according to the provincial model of typhoon disaster assessment, the development of typhoon disaster assessment module, and disaster loss index module.5, Discussion of the typhoon disaster response, risk management measures; This article from the typhoon disaster risk assessment and damage assessment studied two aspects of the typhoon disaster assessment model to compare the characteristics of the models, select models of our assessment of the typhoon. Construction of a typhoon disaster database, selected 134 typical typhoons between 1985 and 2006 Typhoon field data, select the affected area, the death toll, but loss of housing, the four indicators of direct economic losses of China's typhoon losses caused by disasters to carry out an assessment of the situation. Typhoons landing on the location, time analysis of the temporal and spatial distribution of the laws of the typhoon. Through the four indicators were selected to achieve the market index typhoon disaster, through the transfer function of the damage index will be translated into a unified index to quantify the level of losses through the loss of the market index to evaluate the loss of typhoon disasters, vulnerability assessment carried out. Construction of typhoon disaster assessment system, using plug-in development mode, the use of AE components to achieve the secondary development of statistical analysis capabilities to disaster assessment model-based evaluation module for quantitative evaluation of disasters.
