Land use/cover change plays a decisive role in the ecosystem services function, which is a hot and frontier issue in the global environment. In the present study, the effects of land use change are discussed based on the obtained values of ecosystem services in Shimen County from 2001 to 2013, and the change trend of land use change is predicted by the methods that the values of ecosystem services proposed by Costanza (ESV) are calculated with regard to the value coefficients of ecosystem services per unit area in the Chinese terrestrial ecosystem, as well as the Gray Model (1,1). The results showed that:(1) during the studied period, the value of ecosystem services in Shimen County was divided into two stages:the first phase was the rising phase that the value increased from 6.500 7×109 yuan in 2001 to 6.519 9×109 yuan in 2004, the second stage was the declining stage that the value of ecosystem services declined from 6.519 9×109 yuan in 2004 to 6.507 6×109 yuan in 2013; (2) according to the forecast of the amount of land use in Shimen County 2016 to 2025, ESV of Shimen County in 2025 will be reduced to 6.464 1×109 yuan. At the same time, the value of ecosystem services is sometimes increasing or decreasing, while the values of gas regulation, climate regulation, soil formation and protection, and raw materials are reduced, and the values of water conservation, waste treatment, biological diversity protection, food production, entertainment and culture appear to rise. This paper can provide scientific basis and technical support for land use and environmental protection in Shimen County.
