GPS technology has penetrated into all fields of surveying and mapping disciplines, and has been widely used in leveling measurement. By studying the feasibility of the refining of region quasi-geoid based on the existing quasi-geoid, this paper shows a new method which is a combination of the Earth's gravity field model and the GPS leveling fitting method to determine the region quasi-geoid and provide the specific ideas and calculation steps and do analysis and discussion about the feasibility and superiority of this method using actual data. This new method makes full use of the advantages of the high resolution of the gravity geoid and the high-precision of the GPS geoid to realize the complementary strengths.
