The ecosystem evaluation index system and evaluation model were constructed based on GIS and remote sensing, and the temporal and spatial changes of ecosystem service values in Changting County from 2005 to 2016 were evaluated under the impacts of different soil and water conservation measures. The results showed that the ecosystem service values of Changting County spatially presented a trend of high around and low in the middle from 2005 to 2016, and the ecosystem service values in the four stages were 10.108 billion yuan, 8.839 billion yuan, 10.914 billion yuan and 13.411 billion yuan, respectively. Atmospheric balance value accounted for an average of 35%, water conservation value accounted for 15%, soil conservation value accounted for 21%, nutrient recycling value accounted for 4%, and organic matter production value accounted for 25%. The values of various ecosystem service showed a trend of first decreasing and then increasing. Under different soil and water conservation measures, there were significant differences in temporal and spatial changes of ecosystem service values in Changting County. In the towns of Zhuotian, Sanzhou, Hetian and Cewu, the governance effect was good, and the ecosystem service values were increased significantly, but the vegetation coverage of mountainous areas tended to be decreased. It was suggested to implement the modes of grass-shrub-arbor mixed management and old pine rehabilitation in mountainous and hilly areas, and to build drainage ditches, retaining walls and sand basins in the broken bare area of collapsed hills. Besides, interplanting suitable plants under the forest, speeding up the transformation of sloping fields into terraces and implementing the system of division of labor and cooperation were also needed to be considered. In the process of daily production and construction, it was important to pay attention to afforestation, prevent soil erosion, and strictly implement the three-simultaneous system of design, construction and operation of soil and water conservation projects.
