摘要
分析了布格重力异常在地壳构造探测中的重要作用,以及目前地质和物探中常用的地面重力测量计算得到的布格重力异常的缺点,提出利用纯重力卫星数据计算得到的SST(satellite-to-satellite tracking)地球重力场模型来研究地质构造和资源探测,以重力场模型EIGEN-GRACE02S为例,分析了其优点和应用的可行性。针对原有“卫星重力异常”概念的缺陷,提出了“真卫星重力异常”和“假卫星重力异常的概念”。
This paper analyzes the important role of Bouguer gravity anomaly in the detection of the earth＇ s crust tectonics, and the disadvantages of Bouguer gravity anomaly that come from the gravimetry on the ground in the present geology and geophysical prospecting and puts forward a SST gravity model, for example, EIGEN-GRACE02S, from pure gravity satellite data and analyzes its advantages and applicability. With the development of space technology and for surmounting the disadvantage of the concept of ‘ satellite gravity anomaly＇ , this paper puts forward the concepts of ‘real satellite gravity anomaly＇ and ‘pseudo satellite gravity anomaly＇.
