摘　　要：以沙漠区野外近地表调查资料为基础,结合低、降速层的分层情况及常用的几种野外静校正方法的原理,依据各种野外静校正方法的优势和实际资料处理中所存在的问题,提出了一种新的针对沙漠区资料野外静校正的方法——利用层析反演约束近地表模型方法。该方法充分利用了资料的初至信息与野外近地表调查数据资料,获得更为准确的野外静校正量,更好地解决了沙漠区野外静校正问题,在实际资料处理中效果明显。Based on field near surface of the desert data, combined delamination of low and deceleration with the principles of common field static correction methods, a new method, the near surface model method by chromatography inversion constraint, is put forward for field data static correction in desert area according to the advantages of different field static correction method and the problems existing in actual data processing. The method is applied to obtain more accurate field statics by first break information and field near surface inquired data for working out the field static correction in desert area. And good results have been achieved in actual data processing.
