The　precipitation　recharge　coefficient　(PRC),　representing　the　amount　of　groundwater　recharge　from　precipitation,　is　an　important　parameter　for　groundwater　resources　evaluation　and　numerical　simulation.　It　was　usually　obtained　from　empirical　knowledge　and　site　experiments　in　the　1980s.　However,　the　environmental　settings　have　been　greatly　modified　from　that　time　due　to　land　use　change　and　groundwater　over-pumping,　especially　in　the　Beijing　plain　area　(BPA).　This　paper　aims　to　estimate　and　analyze　PRC　of　BPA　with　the　distributed　hydrological　model　and　GIS　for　the　year　2011　with　similar　annual　precipitation　as　long-term　mean.　It　is　found　that　the　recharge　from　vertical　(precipitation　+　irrigation)　and　precipitation　is　291.0　mm/yr　and　233.7　mm/yr,　respectively,　which　accounts　for　38.6%　and　36.6%　of　corresponding　input　water.　The　regional　mean　PRC　is　0.366,　which　is　a　little　different　from　the　traditional　map.　However,　it　has　a　spatial　variation　ranging　from　-7.0%　to　17.5%　for　various　sub-regions.　Since　the　vadose　zone　is　now　much　thicker　than　the　evaporation　extinction　depth,　the　land　cover　is　regarded　as　the　major　dynamic　factor　that　causes　the　variation　of　PRC　in　this　area　due　to　the　difference　of　evapotranspiration　rates.　It　is　suggested　that　the　negative　impact　of　reforestation　on　groundwater　quantity　within　BPA　should　be　well　investigated,　because　the　PRC　beneath　forestland　is　the　smallest　among　all　land　cover　types.
