一、我国抗震防灾的环境影响与特点我国地处世界上两个最活跃的地震带,是多地震国家之一。我国也是世界上有地震历史记载最丰富的国家,有文字可考的历史约有四千多年。自本世纪以来的八十多年内,共发生破坏性地震2600余次,其中六级以上地震500余次,在此期间,经历了四个地震活动高潮期。特别是1966年以来的第四个地震活动高潮期,在我国西南和华北平原发生了一系列七级以上强震,给人民生命财产和国民经济造成了重大的损失。
I. Environmental Impact and Characteristics of Earthquake Disaster Prevention Our country is located in the two most active seismic zones in the world and is one of the countries with many earthquakes. Our country is also the country that records the most earthquakes in history in the world. There are more than four thousand years of history that texts can be taken. Over 80 years since the beginning of this century, there have been more than 2600 destructive earthquakes, of which over 500 were earthquakes of magnitude 6 or above. During this period, they experienced four climaxes of seismic activity. Especially since the fourth seismological upsurge period since 1966, a series of strong earthquakes of magnitude 7 or above occurred in the southwest and north China plains of our country, causing great losses to people’s life and property and the national economy.
