一、小城镇编制抗震防灾规划的必要性 1.震区小城镇面临的严峻形势 通过对历年来地震灾害的分析,有90％以上的地震震中是发生在小城镇和农村。近年来,小城镇发展很快,建设规模和人口规模不断扩大,人口和生命线工程越来越集中,但是,小城镇基本没有设防,抗震防灾意识淡薄,普遍存在麻痹思想和侥幸心理,一旦遇到震害往往损失严重。目前,我国正处于第五个地震活跃高潮期,作为面广量大的小城镇应当引起高度的警惕。
I. The Necessity of Preparing Earthquake and Disaster Prevention Planning for Small Towns 1. The Severe Situation Faced by Small Towns in the Seismic Zone Through the analysis of earthquake disasters over the years, more than 90% of earthquakes have occurred in small towns and rural areas. In recent years, the development of small towns has been rapid, the scale of construction and population has continued to expand, and the population and lifeline projects have become increasingly concentrated. However, small cities and towns basically have no fortifications, and their awareness of quake-resilient and disaster prevention is weak, and paralysis and luck are common. The damage to the earthquake is often severe. At present, China is in the fifth period of active seismicity. As a large-scale small town, it should cause a high degree of vigilance.
