基于灰色关联度的黑龙江省暴雨事件灾害评估和预评估模型研究
Disaster Evaluation and Pre-evaluation models on Rainstorm Events in Heilongjiang Province Based on Gray Correlation
摘要
Abstract
Based on analysis on historical rainstorm disaster data statistics of Heilongjiang Province during 1984-2013 of each station,using the method of grey correlation,degrees of disaster grades are divided.By studying the relationship between rainstorm disasters and meteorological factors,five single index and comprehensive assess-ment index reflecting the rainstorm disaster degrees are established.Evaluation and pre-evaluation models are es-tablished on the basis of all the above work,and ultimately achieve a quick assessment of rainstorm disaster events. Obvious rainstorm disaster events during 2013-2014 are evaluated by the evaluation model,and the results show that the evaluation results are basically consistent with actual situation;the service needs of the decision could be met in a certain degree.关键词
