Kunyu Mountain National Nature Reserve is located in the east of Shandong coastline which is the important ecological barrier area to Jiaodong Peninsula. In order to clarify the main service function of this region and provide a scientific basis for the construction of natural protected area system in Kunyu Mountain, the dynamic changes of land use types and ecosystem service values in this area were examined in this study. We analyzed the dynamic change of different land use types based on the remote sensing image data from 2008 to 2018 by using the equivalent factor method to estimate the ecosystem service value of Kunyu Mountain National Nature Reserve. The results show that the change of land use types in Kunyu Mountain National Nature Reserve from 2008 to 2018 was mainly the transfer between bare land and other land, cultivated land and woodland; among them, the largest increase in area was woodland, while the largest decrease in area was cultivated land, bare land and other land; during the same period, the ecosystem service value of Kunyu Mountain area increased from 336 million yuan to 368 million yuan; the food production function value showed a decrease trend, the value of raw material production, water supply, gas regulation, climate regulation, purifying environment, hydrology regulation, soil retention, maintaining nutrient cycling, biological diversity and aesthetic landscape functions showed the increase trend, the value of climate regulation and hydrological adjusting function increased significantly. This study indicated that the ecological function was the main service function, and the regulating service was the main ecological function of Kunyu Mountain. The woodland had higher ecological service ability among the different types of lands, and also maintained the ecosystem service in Kunyu Mountain. The development of land use structure of Kunyu Mountain Nature Reserve was towards the direction of enhancing ecological function.
