中文摘要：

在青藏高原东部到四川盆地这两个构造单元进行了稳态钻孔温度测量和岩石热导率测试，确定了相应钻孔的大地热流数据。应用这些可靠的热流数据，对横穿这两个构造单元的阿坝一简阳地学断面进行了2-D温度场研究，获得其深部热结构的认识。模拟结果显示，松潘一甘孜地块地表为高热流区域，达到80～110mW／m2，四川盆地地表为中低热流区域，为50～60mW／m2。莫霍面的温度有较大变化，松潘一甘孜地块为1100～1210℃，四川盆地西部减小为750～820℃。热岩石图表现为西部向东部变厚，松潘-甘孜厚度为120～130km，四川盆地西部增加到130～140km。

英文摘要：

Based on the newly obtained data of borehole steady temperature logging and the thermal conductivities values, we determine the corresponding heat flow data of the eastern Tibetan Plateau and the Sichuan Basin. Application of these reliable heat flow data,we analyze the two tectonic units with 2-D temperature field along the Aba-Jianyang geoscience transect to understand the deep thermal structure. The results show that the Songpan-Ganzi block have high surface heat flow values,range from 80 to 110 mW/m2 ,the surface heat flow in Sichuan Basin are low to medium,range from 50 -60 mW/m2. Moho temperature have a great change, vary from 1 100 ~ 1 210 ~C in Songpan-Ganzi block,from 750 -820 ~C in western Sichuan. The hot lithosphere thickens is about 120 -130 km in Songpan-Ganzi block,increase to 130 140 km in western Sichuan Basin.
