Construction and empirical study of natural disaster relief materials reserve demand model:Take Shenzhen as an example
To scientifically manage the reserving of natural disaster relief materials,this study was undertaken based on an analysis of the characteristics of urban disaster relief.Typical disasters that necessitate large-scale population displacement and resettlement,such as typhoon,heavy rain and earthquakes,were selected for investigation.The uniqueness of the materials required for relief in these typical disasters was analyzed,and the fundamental types of natural disaster relief materials were comprehensively determined.A multiple regression method was employed to analyze and decompose the factors affecting the reserve of natural disaster relief materials.A dynamic estimation model for the demand of natural disaster relief materials reserve was constructed,taking into account six related factors:the number of displaced and resettled individuals in historical major disasters,per capita supply usage,supply depletion compensation factor,temporary relief duration,the proportion of people requiring government assistance,and the proportion of people using a particular type of supply.Shenzhen City was used as a study case.Using the highest number of displaced and resettled individuals following typhoon,heavy rain and earthquakes in recent years as the basis for estimation,the standard value for the reserve of natural disaster relief materials in Shenzhen was calculated.
