摘要
对天山地震区存在的壳内高导层和高导层所在地区发生地震的震源深度进行了研究，发现地壳中部的高导层与地震带的震源分布有一定的对应关系，震源深度存在由北向南逐渐加深的趋势，而且与高导层的埋藏深度相当。研究认为，高导层是表征深部震源环境的重要方面之一，它的形成与存在既有内在的原因也应具备一定的外部条件。
The nigh conductivity layer in Tianshan and seismic focal depth in Tianshan region in the layer were analyzed. There is a certain relation to seismic zones and the conductive layers in the midcrust. Hypocenters are in a tendency deeping from north to south along the Tianshan, showing similar depths with those of high conductivity layers. It is believed that high conductivity layer may be one of the important aspects relating to deep hypocenter environment, which may be due to the inherent factors and environmental changes.
