地震区划是贯彻“以预防为主”地震工作方针的一项重要工作。它在整个地震工作中也是一项战略性的任务。它不仅本身是一项中长期预测预报,同时也是防震抗震的前提和基础。它既为各项工程建设提供抗震设防依据,又为国家建设规划、能源开发、土地利用提供地震危险性资料。地震小区划成果还能为城市规划,震害预测,特殊工程(如大型水库、核电站等)设计,研究地震的社会、经济效应,制定防灾、救灾对策提供基本资料。
Seismic zoning is an important task in carrying out the “prevention-oriented” earthquake work guideline. It is also a strategic task throughout the earthquake effort. It is not only a medium-long term forecast, but also the precondition and basis of earthquake-resistant and earthquake-resistant. It not only provides seismic fortification basis for various project construction, but also provides earthquake risk information for national construction planning, energy development and land utilization. The results of the seismic zoning can also provide basic information for urban planning, earthquake damage prediction, design of special projects (such as large reservoirs and nuclear power stations), study of the social and economic effects of earthquakes, and formulation of disaster prevention and relief measures.
