Abstract: According to the opinions on the tracking and evaluation of regional adjustment coefficients of geological survey budget standards in the past ten years, many units undertaking geological survey projects believe that the regional adjustment coefficients are generally reasonable and meet the needs of geological survey project budget management, but there are some problems of improper adjustment coefficients in some regions. Combed the area adjustment coefficient of evolution, this paper summarizes up the problems existing in the regional adjustment coefficient using, analyzed the factors influencing the area cost differences, regional adjustment coefficient to revise plus model is established, based on this, advances the regional adjustment coefficient to revise pattern exploration, adjust the revision coefficient is calculated for the next step to carry out the regional work lay the foundation.
