The precipitation infiltration recharge condition has theoretical and practical significance in the study of groundwater resources. In this study, with the application of remote sensing technology and through constructing evaluation system and model based on expert experience and knowledge, the spatial differentiation of Beijing precipitation infiltration recharge conditions are evaluated at three scales, including grid scale (30 m×30 m), Karst water system bedrock region and its carbonate rock region. The results suggest that carbonate rock areas are conducive to the precipitation infiltration recharge in the whole study area. The precipitation infiltration recharge conditions are in worsening order of Fangshan, Mentougou, Yanqing, Pinggu and Huairou in the five Karst water systems bedrock areas. The precipitation infiltration recharge conditions are in worsening order of Huairou, Mentougou, Fangshan, Yanqing and Pinggu in the five carbonate rock areas, and the lithology and structure seem to be the key factors affecting the conditions of rainfall infiltration recharge.
