青藏高原地震活动及其构造背景

青藏高原是大陆范围内地质作用最活跃的地区。十分强烈的地震活动，清楚显示了以大区域构造为背景的整体性活动特征。在青藏高原的大地构造格局中来研究地震活动和震源性质的变化规律，是认识高原构造活动状态、规律、起因的重要部分。为此，本文综述了近些年该地区地震活动、震源性质、速度结构、地质构造及高原隆起机理的研究。

SEISMIC ACTIVITY IN TIBETAN PLATEAU AND ITS TECTONIC IMPLICATION

Within the range of continent, Tibetan Plateau is the most active region in geologicaleffect. Very strong seismic activity has clearly demostrated the whole characteristics of largeregional tectonics. In order to realize the active tectonic statement in Tibetan Plateau andits regularity as well as its origination, it is an important part that the changing regularitiesof seismic activity and earthquake mecanism are researched in tectonic pattern. For thisreasion, the purpose of this paper is to review some recent years results about seismic ac-hvities, earthquake mechanism, velocity structure and geological tectonics as well as up-lift mechanism of Tibetan Plateau.
