在国家地震局的主持下，于1977年编制并发布了中国地震区划图(比例尺1：300万)，为全国各地区的抗震结构设计和基本地震烈度提供资料。该图是对1973年以后100年基本地震烈度的一种预测。本文讨论了编制该图的主要原则和方法。当然，就目前地震区划的现状而言，所采用的原则和方法存在许多缺陷，因此该图在预测地震烈度方面的可靠性仍存在较大不确定性。
Under the auspices of the State Bureau of Seismology a seismic zoning map of China (scale 1:3,000,000) has been compiled and issued in 1977 for the purpose of providing data for anti-seismic constructional designing and basic seismic intensity of various regions of the country.The basic seismic intensity of a region is defined as the maximum intensity to be suffered within a given interval of time in the future under the site condition of that region. The map is a sort of prediction of the basic seismic intensity for the next 100 years after 1973.In this paper, the major principles and methods in composing this map are discussed. Of course, as far as the present state of art of seismic zoning is concerned, the principles and methods used involve many shortcomings and therefore the reliability of the map in predicting seismic intensity is still rather uncertain.
