Based on the analysis of the ecological restoration characteristics of Yan’an City, we explained its impact on the ecosystem service function, and used the STIRPAT model to explore the quantitative relationship of ecological restoration process of cultivated land change and human driving factors. The results show that the main landscape pattern of Yan’an City in 2000—2013 was cultivated land, woodland, grassland, while the cultivated area reduced greatly, forestland and grassland area increased steadily. The forestland and grassland mostly resulted from the conversion of the cultivated land, which accounted for 28.627% and 66.664% of its changing amount, respectively. The ecosystem service value of Yan’an City has steadily increased during the period from 2000 to 2013, of which the growth rate was 7.624%, and the average annual growth amount was 141.6 million Yuan. The ecosystem service value contribution rates of arable land, grassland, forestland were increasing, and the proportion of construction land increased gradually, but the water body and desert were fluctuation. On account of the coefficient of variation decreasing, the ecological service function showed the development trend of equalization. The increasing population, social economic growth and industrial structure adjustment have the positive effect on decrease of arable land area, but the increase of non-agricultural population and the level of the rural economy can promote the cultivated land growth and the effective utilization of cultivated land. All driving factors combined to affect the change of cultivated land area, the ecological restoration and the structure of ecosystem, then the influence of the regional ecosystem services is notable.
