摘　　要：在分析研究青藏高原东北缘地震、地震形变带及活动断裂带的基础上，确定了ＮＮＷ向最新活动构造体系。该体系的主体构造是由一系列呈ＮＮＷ向相间展布的现代隆起带和沉降带组成。青藏高原东北缘最新构造变形是该构造体系活动的结果。另外，还对体系的变形特征及“敏感点”A recently active tectonic system which strikes NNW is determined by analyzing and Studying the earthquakes, seismic deformation bands and active fault zones along the northeastern margin of the Qinghai Tibetan Plateau. It consists mainly of a series of modern uplifts alternating with sudsidence zones. The latest tectonic deformation along the northeastern margin of the plateau was found to have resulted from the activity of the system. In addition, a more detailed discussion of the deformation of the system and the earthquake prone areas is made.
