Abstract:
With support of the remote sensing and GIS,the social economics data and the character of extreme flood disaster spatial information grid are given through which the loss of extreme flood spatial information grid is allowed. Through this grid,this paper gives the loss in each unit,the expected value and the distribution using the extreme value theory and partitioned multi-objective risk method(PMRM). This paper selects the example of Harbin city and gives the estimation loss of extreme flood disaster using the spatial information grid in 1998. With support of Matlab simulation,this paper gives the estimation of loss for extreme flood disaster whose distribution is proved to be generalized Pareto distribution. The parameter estimations are showed by using the method of MLE.
