摘要
本文研究了1966—1976年间华北断块区地震幕活动与大华北地区1960年2月—1977年1月气温异常时空演化之间的关系。主要结论如下:1.华北地区1960年2月(增温)和1971年1月(降温)以及1975年9月和1976年2月(增温)的气温增温—降温过程与地震幕活动开始和结束时间相关联;2.气温异常时间与范围之间以及它们与地震能量之间有较高的可信度;3.1960年2月—1976年7月28日唐山7.8级地震时的16.5年可按0.618~N划分18个时段,地震幕中单个地震及天气增温的时间恰好位于某几个时段中。
This paper has made a study of the relationship between the seismic screen activities in the North China block area from 1965 to 1976 and the temporal-spatial evolution of temperature anomalies in the Greater North China from February 1960 to January 1977. The principal conclusions are: (1 )The atmospheric temperature increment (February 1960, September 1975, and February 1976,) and decrement (January 1977) in North China are related with the start and close of the seismic screen activities; ( 2) The credibility of atmospheric temperature anomalies between time and space and the temporal-spatial temperature anomalies and the seismic energy is great; ( 3 ) The individual earthquakes in the seismic screen and the atmospheric temperature increment concurred in certain temporal phases if the 16.5 years from February 1960 to July 28, 1976 when the M7.8 earthquake in Tangshan occurred is divided by 0.618N into 18 phases in time.
