摘要
针对辽河盆地新生代拉张多期性的特点，提出一种适用于多期拉张盆地构造热演化模拟的纯剪切模型．该模型考虑了多期拉张的继承性、横向不均匀性以及拉张速率的可变性。通过几种拉张速率模式的对比，指出拉张速率模式的选择对模拟年轻盆地热演化过程具有重要意义．最后，利用该模型模拟研究了辽河盆地新生代的构造热演化历史．
In view that Liaohe basin was stretched multiply during
the Cenozoic,a pure shear model is put forward to suit for tectono-thermal modeling of multiple
stretchingbasin.This model has considered the inheritance of multiple stretching,the stretching
nonuniformity and the variety of stretching rate.By contrast of several kinds of stretching rate, it
shows that selection of stietching rate has great significance inmedeling the evolution process
of young basins.In the end,the model is applied tostudy the thermal history of Liaohe basin in
the Cenozoic.
