Abstract: Ecosystem service is the foundation for human to rely on for survival and development. Wuyishan City, Fujian Province was selected as a case for the study to assess economic values of the following 8 types of ecosystem services:products supply, water supply, water purification, climate regulation, soil conservation, carbon-sequestration and oxygen-release, tourist entertainment and biodiversity conservation. Results show that the total of the ecosystem services in Wuyishan City was valuated at 55.064 billion yuan. Among them, the tourist entertainment service contributed the most, contributing 28.84%, the soil conservation service came the next, contributing 22.15%. Spatial distribution of the ecosystem services in the city in terms of importance was analyzed, showing sharp differences between areas. The southern part of the city, home to the Wuyishan National Scenic Spot, Xingtian Town and the Wuyishan National Nature Reserve were areas of extreme importance and great importance in ecosystem service, while Langu and Wutun Township in the northeastern part and Wufu Town in the southeastern part were areas of importance and general importance. The valuation of the ecosystem services may serve as theoretical basis for scientific management and protection of the ecosystems and ecologically critical areas in Wuyishan City.
