Method.
Background technique
China is located at circum-Pacific seismic belt and Eurasian seismic belt intersection part, and earthquake is more, intensity is big, distribution is wide, focus
It shallowly, is to be influenced one of country the most serious by earthquake disaster in the world.According to statistics, 20 th century of China occur 6 grades altogether with Shangdi
Shake more than 650 times: wherein 7 grades of Richter scale earthquake 100 times, 8 grades or more earthquake 10 times;Death toll caused by earthquake up to more than 610,000 people,
Account for about the 36% of world's earthquake total toll, occupies first place in the world.In fact, being deposited after the earthquake according to Post disaster relief experience
The survival of the wounded will be greatly improved if timely, scientific rescue can during this period of time be unfolded at one " gold 72 hours "
Rate.But after the earthquake, rescue facility often damages seriously, and material equipment loss is huge, and disaster area has no ability to immediately
Carry out emergency self-saving;And topography and geomorphology variation is huge, and traffic barrier, external rescue strength, which cannot be introduced into disaster area, carries out rescue in time
