摘　　要：本文应用辽南地区大地热流值观测和闾阳—海城—东沟综合地球物理剖面成果,计算和研究了辽南地区地壳与上地幔介质的温度结构特征,发现海城地震区具有以下主要特点:壳内低速—高导层具有较高的温度值;震区岩石圈温度值最高:震区高热流异常值基本上是由壳内的低速—高导层提供的等。这些重要发现,为解释海城地震的力源及高热流异常从温度结构方面提供了重要依据。The heat flow observations is the south of Liaoning are applied to calculating and studying temperature structure of the crust and upper mantle in the same area. Combining with other ge- o physical data of Luyang-Haicheng-Donggou profile, we find that Haichene seismic area posse- sses the characteristics of temperature structure as follows: there is higher temperature in the low velocity-high conductivitylayer in the crust; there is the highest temperature in the lithosphere
