| 英文摘要 | Eastern margin of Tibetan plateau belongs to north-south seismic belt. There is a distinct variation characteristic of gradient zone of positive and negative anomaly on satellite anomaly figure of free air gravity. Along the anomaly zone, there are many deep faults. The eastern margin is also a boundary region of tectonic units. In this paper, we used the gravitational admittance theory and method to compute the background isostasy anomaly of gravitational admittance model in this region. Through comparing the isostasy anomaly characteristics of Airy model and elastic plate model and analyzing the regional seismic activity, we evaluated the results and optimized the parameter used for calculation. Based on this, we finished the comparison and analysis of isostasy anomaly response characteristics along three profiles across the eastern margin of Tibetan plateau, and taking this isostasy anomaly background as the reference field, further explained the temporal and spatial features of mobile gravity measurement dataset of 1998 similar to 2005. |
