摘　　要：长9沉积前,研究区湖盆底形为限定性的隆洼相间的地貌格局。通过求取现今地层厚度、去压实校正和古水深校正,综合利用钻井和地球化学资料,恢复了长9的湖盆底形。Before the deposition of the Chang 9 formation,the bottom configuration of the lake basin in the study area is a determinant geomorphic pattern of the interphase between the uplift and the depression.By taking the current formation thickness,de-compacting correction and paleo-bathymetric correction,the drilling and geochemical data were comprehensively utilized to restore the bottom configuration of the Chang 9 lake basin.
