The evaluation of forest ecosystem service function is a hot topic at home and abroad. Forests bring not only economic benefits but also ecological benefits for humans. Based on the Forest Resources in Shanxi Province Report of 2016 and the standard specifications of the People's Republic of China (LY/T1721-2008, "Specifications for assessment of forest ecosystem service in China"), this study evaluated the value of main vegetation types of 11 cities in Shanxi Province. The results showed that: 1) the total value of forest ecosystem services was 3172.64 billion yuan in Shanxi Province in 2016, with high to low value observed in the order of water storage, air quality purification, soil conservation, carbon fixation and oxygen release, biodiversity conservation, nutrients accumulation, and forest recreation. Water storage, air quality purification, and soil conservation contributed 78.98% of the total ecosystem value; 2) the order of forest ecosystem services in cities from high value to low value is Lvliang, Xinzhou, Linfen, Jinzhong, Changzhi, Yuncheng, Jincheng, Datong, Taiyuan, Shuozhou, and Yangquan. The highest and lowest cities for monetary values per hectare of land are Jincheng and Shuozhou, respectively; 3) the order of forest ecosystem services in the stand forest from high value to low value is arboreal forest (Pinus tabuliformis, Quercus spp., mixed broadleaf-conifer forest, broad-leaved mixed forest, Betula spp. and Populus davidiana, Larix gmelinii, Populus spp. and soft-broad tree, Sophora japonica, Cupressus funebris, Coniferous mixed forest, Picea asperata, hard-broad tree, and bamboo grove), shrubbery, and economic forest; 4) the order of forest ecosystem services based on age-group from high value to low value is middle forest, young forest, mature and over-mature forest, and near-mature forest.
