In this paper, writers analyzed the Tarim lithosphere thinning mechanism based on the tectonic thermal evolution quantitative method, and discussed three possibilities:the hotter India asthenosphere intruded under the Tarim lithosphere and made the Tarim lithosphere became unsteady;the bottom of Tarim lithosphere is heated by friction of the atheonosphere flow and washed off by the hot asthenosphere; the Xizang lithosphere delamination induced the convection, and the upflowing mentle heated the bottom of the Tarim lithosphere and make it enthinning.

本文利用构造热演化方法对塔里木岩石圈减薄的热演化过程进行了定量分析，探讨了塔里木盆地岩石圈减薄可能的三种机制：印度板块与欧亚板块碰撞后青藏高原岩石圈底部的软流圈较塔里木盆地岩石圈底部的软流圈的温度要高，青藏高原的软流圈地幔向塔里木盆地岩石圈底部侵入形成的热扰动使得塔里木盆地岩石圈底部的温度升高；塔里木岩石圈与其下流动的软流圈的摩擦剪切生热导致其岩石圈地幔底部温度升高，使得岩石圈底部发生热侵蚀，从而使得与软流圈接触的岩石圈地幔不断地加入到软流圈地幔；在塔里木盆地岩石圈的下部，青藏高原的岩石圈在该处发生了拆沉，从而诱发的软流圈地幔对流，上升的软流圈地幔流使得岩石圈地幔的温度升高而熔融，成为软流圈地幔。
