The government work for rescue and reconstruction, and budgeted for the reconstruction. This kind of budgets could likely be seen as the measurement of hazard risk. For example, insurance is the assessment of probability and damage of an accident, and assessing the value of settlement of claims. This value is seen as the measurement of accidental damage. For this reason, we suppose the hazard reconstruction budget as the measurement value of hazard damage. This value could provide the risk assessing model for the use of estimation and correction, let the model could correctly reflect the hazard risk. The main research subject of this study is the engineering budgets of rescue and recovery of debris-flow proved by Soil and Water Conservation Bureau. First of all, understand the framework of risk assessment and the element of debris-flow by literature review. Second, analysis the contents of the engineering budgets, and try to use it in the framework of risk assessment. We try to find the probability of the use of engineering budgets by two parts of experiment, hazard risk zoning map and regression analysis. According to the results of experiment, engineering budget’s concept is close to the meaning of vulnerability. And we can use this kind of data in making of risk zoning map. But if this kind of data is used in making of risk assessing model, the setup of model and the content of elements should be improved.
