| 摘 要： | In the day time of the Moon surface, the strong illumination from high altitude and high albedo rate radical craters will introduce the illumination effect on observing the nearby low altitude, low albedo rate and shallow small slop rate area seriously, and even can ＂hide＂ the later area from the light. Based on the lunar global topography model obtained by Chang＇E-1 mission, and by comparing with the lunar gravity model, a volcano named ＂YUTU Mountain＂ has been identified. It is a volcano with diameter of -300 km and height of -2 km located at （14°N, 308°E） in Oceanus ProceUarum. Besides, the DEM of another volcano named ＂GUISHU Mountain＂ in the same area has been improved. This new discovery will benefit the study of lunar magmatism and volcanism evolution in the nearside of the Moon.
