Abstract：This article uses GIS technology,InVEST model and economic valuation models as the assessment methods to assess the value and the spatial distribution of coastal ecosystem services in Longhai coastal city over the past 30 years (1986~1996) based on The Millennium Ecosystem Assessment framework proposed by the UN.The results reveal that the overall value of ecosystem services in Longhai City decreased between 1986 and 1996,especially in Nanxi Estuary,Zhuoqi Town district,Haimen Island,and zhangzhou development zone.The value of services provided by seven coastal zones in Longhai City varies spatially with Zhuoqi Town,Haimen Island,and Longjiao Estuary providing the much higher valuable ecosystem services value whereas Longhai City Center provides the least valuable ecosystem service value.Due to the presence of mangroves in Nanxi Estuary,Haimen Island,Zhangzhou Development Zone and Zini Island; the value of the ecosystem services provided by the mangroves are relatively higher in these areas.Of all the ecosystem services,Pollution treatment and control service,recreational and nutrient retention services have been revealed to be more valuable than other ecosystem services.This paper will potentially serve as a reference document to land managers for Longhai coastal spatial planning and management.
