Abstract: In view of the features (complicated and changeable superficial structures, closely set obstructions on earth surface) of central uplift belts in Dong sag, the design target is refined, the process of links target administration is discussed, the single line design, conclusions, themeans and requirements of point layout and the administration target of procedure links are elaborated in this paper. CDP offset distribution target may be used to control the evading obstructions design, so as to make the minimum binning fold more uniform, meet the delicate requirements of point exactitude, obtain accurate surface investigation scheme and little explosive compensation plan. All these indexes, treatments and measures may ensure the quality of high-precision acquisition in complex surface area.

Key words: design target refinement, links target administration, high-precision acquisition quality, complex surface area, Dongpu sag
