The ecosystem services of forests are closely related to human welfare and have become an important component of the global economy. In this study, we estimated the ecological benefits of forests in Jinan, according to the assessment standards of the People's Republic of China (LY/T1721-2008 Specifications for assessment of forest ecosystem service in China). We concluded that the forest ecosystem in Jinan has an annual value of 26.44 billion yuan for water conservation, soil conservation, carbon fixation and oxygen release, nutrient accumulation, purification of atmospheric environment, biodiversity conservation, forest protection, and forest recreation. Among these, water conservation, carbon fixation and oxygen release, and biodiversity conservation were ranked as the top three most valuable services. The value of forest ecosystem services in different counties could be ordered as follows:Licheng > Changqing > Zhangqiu > Pingyin > Shanghe > Jiyang > Shizhong > Tianqiao > Lixia > Huaiyin. In addition to the forest protection function, the spatial pattern distribution of the value of other forest ecosystem services generally shows the following trend:Southern part > Northern part > Central part.
