| 摘 要： | 针对传统灰靶模型等权的计算模式,引入熵权对模型加以改进,由此建立基于熵权的改进后灰靶模型。以湖南省为例,对13个地级市洪涝易损性等级进行评价。评价结果表明,该方法思路清晰,计算简洁,且评价结果可靠,具有一定的推广运用价值。 |
| 关 键 词： | 城市洪涝易损性评价 灰靶模型 熵权 等级 |

| Abstract: | According to the calculation of equal weight of traditional grey target model,entropy weight is introduced to the model,then the improved grey target model based on comprehensive weights was proposed.Take Hunan province as an example,flood vulnerability degree of its 13 prefecture-level city was evaluated.The results show that the method has clear mind,simple calculation,and reliable evaluation,so it has certain application value. |
| Keywords: | vulnerability assessment of urban flood-waterlogged grey target model entropy weight degree |
