As the latest development of ecological footprint model, three-dimensional ecological footprint model can play an important role in the evaluation of land carrying capacity. The classical three-dimensional ecological footprint model was revised by adjusting the account type. Anhui Province was taken as an example. We calculated the productive land footprint, the land carrying capacity and footprint depth in the period from 2009 to 2016 by using the improved model, and analyzed the natural capital occupancy and its driving forces on the basis of the discriminant of land carrying state. The results showed that the land footprint in Anhui Province from 2009 to 2016 presented the trend of first increase and then decrease, among them, the cultivated land and forest land footprint affected by pollution accounted for larger proportion, and was far above the grass footprint. The footprint of the land and all the types of footprints were higher than the land carrying capacity. The footprint depth varied between 2.1 and 2.6, indicating that the insufficient natural capital flow leaded to the consumption of capital stock and had become the normal state of economic and social development in Anhui Province. The suggestions of land carrying capacity promotion were proposed according to the results of the analysis.
