Abstract:By using value coefficient method to estimate the ecosystem service value of non-construction land, prevention and alternative cost method to estimate the ecosystem service value affected by construction land, and torque balance point method to calculate the spatial distribution gravity centers of regional land ecosystem service, the spatiotemporal differentiation characteristics of land ecosystem service value were analyzed in Fuzhou City. The results showed that: the land ecosystem service value decreased to 91437.19 million Yuan in 2004 from 95541.91 million Yuan in 1993 in Fuzhou City, and increased to 99192.32 million Yuan in 2009. Wood land and water area contributed about 87%~92% of the total ecosystem service value among all the land use types, while the negative effects of construction land on the total ecosystem service value had gradually increased from 1996 to 2004 to 2009. The transfer directions of the spatial distribution gravity centers of land ecosystem service were according with the urbanization directions of the city during the two study periods, which were also affected by the environment sustainable development strategies of the region. According to the spatial distribution characteristics of land ecosystem service in each county of Fuzhou City, it was divided into three ecological function zones, which were ecological zone of artificial regulation, ecological zone of semi-natural and semi-artificial restoration and ecological zone of natural regulation.
