新疆破坏性地震综合等震线图的绘制与分析研究

摘要

Under principle of using original data, We collected 119 isoseismal line maps in Xinijang and filled up intensity area with attenuation relationship. According to intensity attenuation relation-ship we calculated comprehensive isoseismal line for destructive earthquakes without isoseismal line map. With influence of macroscopic epicenter changed, the high intensity area was increasing.%收集到新疆地区119副地震烈度等震线图，在充分尊重原始数据的原则下，利用中国新疆区衰减关系将烈度区补充完整。无等震线图的破坏性地震，通过烈度衰减关系计算得出烈度等震线图，将这些烈度等震线图汇总绘制综合等震线图，将得到的综合等震线图与中国综合等震线图对比，受一些大地震的宏观震中有所改变和近几年发生的破坏性地震的影响，高烈度区面积有所增加。
