It is of great theoretical and practical significance to study the impact of the change of cultivated land spatial pattern on the supply capacity of cultivated land ecosystem services, which can provide scientific reference for the optimization of cultivated land spatial pattern and the protection of cultivated land ecology in China. Previous studies lacked comprehensive research on the dynamic change of cultivated land ecosystem service supply capacity in China. Based on the in-depth analysis of the spatial pattern change of cultivated land, we constructed the spatiotemporal heterogeneity evaluation model of cultivated land ecosystem services in China at patch scale, evaluated the service value of cultivated land ecosystem in China from 2000 to 2015, and explored the evolution law of the supply capacity of cultivated land ecosystem services in China. The results show that:(1)from 2000 to 2015, the gravity center of cultivated land continued to move to the northwest, while the gravity center of paddy field and dry land moved to the northwest and northeast, respectively; the dry land increased continuously in arid and semi-arid areas of north China, the paddy field increased continuously in Northeast Plain, and the cultivated land decreased continuously in other agricultural areas.(2)from 2000 to 2015, the total value of cultivated land ecosystem services and the value of cultivated land ecosystem services per unit area decreased by 1.35% and 0.55%, respectively; the total value of cultivated land supply services and the value of cultivated land supply services per unit area increased, the total value and unit area value of regulatory services, support services and cultural services decreased;(3)the spatial differentiation of cultivated land ecosystem service value change in China was obvious; the total ecosystem service value of cultivated land in arid and semi-arid areas of northern China and Northeast Plain increased, but the ecosystem service value of cultivated land per hectare decreased; the total value of cultivated land ecosystem services and the value of cultivated land ecosystem services per unit area decreased in the Qinghai-Tibet Plateau; the total value of cultivated land ecosystem services in other agricultural areas decreased, while the value of cultivated land ecosystem services per unit area increased. the supply capacity of cultivated land ecosystem services should be effectively improved through optimizing spatial pattern of cultivated land, accurately implementing the strategy of cultivated land recuperation and establishing ecological protection compensation mechanism.
