利用航磁资料和三维磁性层反演方法，对四川盆地及其西部边缘地区航磁异常进行了数据处理，求取了研究地区内居里等温面的定量埋深．以区域构造特征、地温梯度分布和人工地壳测深结果印证了反演结果的可靠性．通过深部地热场的分析讨论，论述了四川盆地西部边缘地区的地震，是在川青块体和康滇菱形块体与杨子板块碰撞作用下，产生了强烈的应力积累；又由于地幔热流的上涌，中、下地壳发生塑性蠕变，为岩石的裂错和应力的释放提供了调整单元深部环境下的孕育和发生．
The aeromagnetic anomalies in the Sichuan Basin and its western margin are processed by using the aeromagnetic data and 3-D magnetic layer inversion method. The quantitative buried depth of the Curie isothermal surface in the study area is obtained. The reliability of the inversion results is verified by regional tectonic features, geothermal gradient distribution and artificial crust sounding results. Through the analysis and discussion of deep geothermal field, it is discussed that the earthquake in the western margin of Sichuan Basin resulted in strong stress accumulation under the collision between the Sichuan-Qinghai block and the Kang-Yunnan rhombic block and the Yangzi plate. Due to the heat flux in the mantle Upward, middle and lower crusts undergo plastic creep, which provides for the gestation and occurrence of deep cracks in the rocks and the release of stress.
