摘要
地震应急救援是一个很复杂的过程,对地震应急救援辐射的研究需要用一种理论模型来刻画和描述。用辐射能力来反映外部的救援能力,结合城市空间相互作用的研究理论,建立了地震应急救援辐射模型,并以芦山7.0级地震为例,计算了芦山县与四川省其它地级市之间的时间距离及各市对芦山的辐射能力,在此基础上分析了各地市的地震应急救援辐射能力。辐射能力最强的是成都市,其次是绵阳、德阳、南充等地市,辐射能力最弱的是攀枝花、甘孜藏族自治州、阿坝藏族羌族自治州等市州。
Earthquake emergency rescue is a very complex process. Research on earthquake emergency res- cue radiation needs to be characterized and described by a theoretical model. By using radiation ability to express the disaster relief come from cities or counties outside of disaster area, and combing with the theory of urban spatial interaction studies, an earthquake emergency rescue radiation model is established. Taking Lushan M7.0 earth- quake for example, time distance between Lushan and other prefecture-level cities in Siehuan Province and the ra- diation ability of other prefecture-level cities to Lushan are calculated. Radiation ability of those prefecture-level cities are analyzed, and results show that Chengdu has the strongest radiation, Mianyang, Deyang, Nanchong etc. have the moderate radiation, Panzhihua, Ganzi Tibetan Autonomous Prefecture and Aba Tibetan and Qiang Autono- mous Prefecture etc. have the weakest radiation.
