We analyzed the evolution of Beijing’s urbanization level with the entropy method from 1993 to 2013. Based on the remote sensing images in 1993, 2003 and 2013, the spatial and temporal variation characteristics of land use and ecosystem services were examined by using GIS technology and InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) models. The effects of urbanization on ecosystem services were also detected in Beijing. The results showed that the urbanization of Beijing continuously increased from 1993 to 2013. The urbanization represented the fast development of the society and space urbanization, followed by the population urbanization, and the economy urbanization was the weakest. The land use had a great change: urban construction sites and grassland area increased, forest area slightly increased, and farmland and water area decreased. Carbon sequestration service increased firstly and then decreased, with a reduction of 5% carbon storage in total in the past 20 years. Water supply service and sediment retention increased by 216% and 76%, respectively. The increased forestland and grassland and decreased farmland improved the ability of sediment retention. The expansion of forest improved the ability of carbon sequestration service from 1993 to 2003, but temperature and precipitation had decreased this ability since 2003. The increase in population gathering and hardened ground were the main reasons for increased water supply service. Owing to the limitation of water supply service, we suggest to stop or slow the speed of the urbanization in Beijing, and focus on the development quality of society and economic urbanization.
