Abstract:: Ecosystem service value assessment is always a research focus of ecosystem services. It is a great significance of understanding the value of ecosystem services features for making reasonable ecosystem management targets. Taking the key ecological function area: Yichang City as study area, based on the land use vector data in the years of 2000，2005 and 2010, we analyzed the spatiotemporal differentiation characteristics of ecosystem service values in Yichang City by using value coefficient method to estimate the ecosystem service value. The results showed that: (1) the ecosystem service value was relatively stable with average annual growth rate of 0.01%, the total ecosystem service value was about 34.2 billion yuan/year, the woodland contributed about 80% of the total ecosystem service value among all the land use types, the service value of water conservation was the highest among all the ecosystem service function types, and accounted for 16.8% of the total; (2) the ecosystem service value of Yichang City presented a pattern of high value in the western part and low in the inner city and southeastern part; (3) according to the spatial distribution characteristics of ecosystem service value in each county of Yichang City, it was divided into three ecological function zones: urban environment maintenance zone, agricultural ecological reserve zone and ecological security barrier zone, based on which it was suggested to formulate the corresponding development strategy targets.
