摘　　要：孔雀河地区位于塔里木盆地东北缘,该区泥盆纪-三叠纪地层的残存分布很局限,地层剥蚀量较大,选择正确的恢复地层剥蚀厚度方法很重要。针对研究区实际资料情况,提出了一套可行、适用的剥蚀量恢复方法,利用构造横剖面法结合沉积厚度外推法,对本区寒武系-下奥陶统、中上奥陶统、志留系、石炭系、三叠系和侏罗系六个顶面剥蚀厚度进行了恢复,并分析了各层顶面剥蚀量的变化规律。The Kongque river area is located at the Tarim basin Northeast edge,in this area Devonian period-Triassic Period stratum's distribution is limited,the stratum denudation quantity is big,choosing the correct restoration method of stratum denudation thickness is the most important.At present there are many methods used to estimate the stratum denudation thickness at home and abroad.In view of the research area actual material situation,we proposed a set of feasible and suitable denudation quantity restoration method. With the application of the structural cross section combined with deposit thickness extrapolated method,we restored the regional six top denudation thickness of the Cambrian-lower Ordovician,the mid-upper Ordovician,Silurian,Carboniferous, Triassic and Jurassic and analyzed each top denudatoin quantity change rule,which had certain guarding function to the area paleostructure situation and oil-gas exploration research.
