Abstract: The paper focused on the changes in natural capital use of urban and rural lands. It redefined the land footprint and land carrying capacity from the production perspective, and applied a revised 3D land footprint model which can differentiate the flows and stocks of natural capital between the scales of product, land and region. Then, the land natural capital use of Guiyang City in 2000-2014 was investigated. The results show that the mobility of natural capital flows increased by 39.4% while the depletion intensity of natural capital stocks decreased by 15.7%. There was a significant change in the composition of land natural capital use, as proven by the growing diverse sources of natural capital flows. Specifically, the largest appropriation of flows and depletion of stocks of land natural capital was found in cropland. However, the gap between cropland and other four land types was shrinking as a result of the reform of the supply front. The dietary supply patterns in Guiyang transformed from crop-dominated to vegetable-dominated. The expanding flows of natural capital benefitting from ecological surplus allowed the forest to have the second-largest share of natural capital use. The stock-flow utilization ratio of natural capital declined remarkably when it comes to the grassland, irrespective of the considerable risk of rebound. The built-up land attracted many of the natural capital flows and thus replaced grassland to be the third-largest land type in terms of natural capital use. There was a significant positive correlation between the magnitude of natural capital use in built-up land and the urbanization rate of Guiyang. The water body accounted for the least amount of natural capital use, and its natural capital use shifted from stock depletion-dominated to flow appropriation-dominated. The research to some extent exposited the nexus between the land use change and the flow-stock dynamics of natural capital in Guiyang City, and thus provided a reference for further scientific discussions on improving the robustness and standardization of footprint methodologies.
