摘　　要：盆地热历史的恢复和重建,根据不同尺度,其研究方法分为构造热演化法和古温标法。其中构造热演化法是在岩石圈尺度上,对其构造演化下的热流变化进行模拟,结合盆地沉降与埋藏,恢复盆地热历史。由不同地球动力学背景差异形成的盆地类型应用不同热演化模型,拉张盆地、走滑盆地多用拉张模型来描述,前陆盆地等以挤压模型来描述。而古温标法则是利用盆内可记录古地温的有机质、矿物等进行盆地热史的重建。镜质体反射率、粘土矿物和流体包裹体等记录的是其经历的古温度峰值,利用磷灰石裂变径迹则可反演其所经历的热史路径,不同盆地条件应用不同的古温标法。According to the different scales, research methods of rehabilitation and reconstruction of basin thermal history are divided into tectonic thermal evolution and. The tectonic thermal evolution method is to simulate the change of heat flow to restore the basin thermal history through combining with the basin subsidence and burial based on the lithosphere scale under the tectonic evolution. Different type of basins formed by different geodynamic background should use different thermal evolution model, extensional basin and strike-slip basin should use multi-purpose tension model to describe, foreland basin should use the squeezing model to describe. The ancient scale method is to use organic matter and minerals in the basin for the reconstruction of the basin thermal history. Vitrinite reflectance, clay mineral and fluid inclusions record are the experience of the ancient peak temperature.
