雾灾

首先，基于灾害系统的理论，构建了雾灾灾害系统模式和灾害链模式，提出了以机场和高速公路为承灾体的雾灾灾害链。

According to the theory of disaster system , the patterns of fog disaster system and disaster chain are established , disaster chain of fog with airport and freeway as the exposure are put forward .

最后，以2002年12月的一次大雾天气为例，运用灰色关联度方法，着重对机场客运的雾灾灾情进行了评估，以期为雾灾损失厘定和防灾减灾提供科学的依据。

Finally , giving an example of fog weather in Dec. 2002 , fog disaster effect on airport was estimated with the method of grey correlation , and some scientific basis for loss determination of fog disaster and disaster mitigation are put forward .

危险性、脆弱性及易损性按5：2：1的分配比例综合测算雾灾的风险指数。

Moreover , the dangerousness , fragile , and vulnerability is composed by5:2:1 to integrally measure the risk index of frog in urban area .
