The results showed that the value of forest ecological services in Nanjing was 30.01 billion RMB/a,and the order of its service value was water conservation>forest tourism>biodiversity>carbon sequestration and oxygen release>air purification>soil conservation>forest protection>nutrient accumulation of forest trees>temperature regulation. Among them,the sum of water conservation,forest tourism,biodiversity and carbon sequestration and oxygen release value accounted for 88.09% of the total value,which were the main service functions of forest ecosystem in Nanjing City.
