| 摘 要： | 水灾严重威胁着人类的财产与生活,水灾灾情等级的合理评估可以为防灾、减灾以及备灾工作提供科学的依据。通过改进象限法的临界指标,并用灰色关联法进行约束,提出基于象限法和灰色关联法的灾情等级评估方法。首先应用象限法对中国(除港、澳、台地区)的水灾灾情按省进行分级,再应用灰色关联法计算出代表各地区灾情大小的关联度,最后用各省的关联度对象限法的分级结果进行微调,得到中国一些地区水灾灾情等级评估的最终结果。结果表明:湖北、湖南、安徽为大灾地区;四川等19个地区为中灾地区;甘肃、海南、青海和新疆为小灾地区;北京、上海、天津、宁夏、西藏为微灾地区。

| Abstract: | Flood affects human property and life seriously.Reasonable grade evaluation of flood loss can provide scientific basis for disaster prevention and mitigation.In this paper,the grade evaluation of disaster loss based on quadrant method and grey association method was proposed,in which,the critical index was improved and the grade was restrained by the gray association method.A flood example in China was given.Firstly,the quadrant method was applied into classifying the flood loss in provincial level.Then,the... |
