GOCE卫星监测的中国区域重力异常
|
摘要
介绍了利用最新一代重力卫星GOCE(Gravity field and steady-state Ocean Circulation Explorer)重力场模型数据计算重力异常的原理和方法,采用最新发布的GOCE重力场模型数据(2009年10月-2010年7月)计算了中国区域(70°～130°E,15°～55°N)的重力异常,为了进一步分析重力异常与区域地质构造及地震活动性的对应关系,将计算结果与中国区域地形、地震活动区域等资料进行了对比分析,结果表明利用GOCE重力场模型数据计算的重力异常能够较好的反映区域地质构造分布特征,而且强震震中通常位于重力异常变化剧烈的高梯度带上.
The methods of computing and analyzing gravity anomaly were introduced in this paper.The gravity anomaly in China(70°～130°E,15°～55°N) were calculated using the latest GOCE gravity field model data(from Oct.2009 to Jul.2010).In order to analyze the relationship among the gravity anomaly,the regional geological tectonics and the seismic activities,we compare the computing result with the topographical data and partial strong earthquakes in the study region.The result shows that the spatial distribution characteristics of gravity anomaly computed by GOCE data had good consistency with the geological tectonics in this region.On the other hand,the strong earthquakes usually occurred in the steep gravity gradient zone.
