Abstract: Natural capital trends of Shenyang from 1995 to 2014 were analyzed using improved three-dimensional ecological footprint model. The results showed that, from 1995 to 2014, the ecological carrying capacity per capita of Shenyang fluctuated within a narrow range generally; the per capital ecological footprint, ecological deficit, footprint size and the footprint depth per capita increased along a wave-like curve. The changing rates of footprint size and depth tended to stabilize gradually. The way of natural capital utilization of cultivated land changed from capital flow in 2004 to capital stock, the capital stock replaced capital flow and became a source to meet the need of na-tural resources in the regional cultivated land, the use ratios of stock-flows increased gradually. The capital flow had been used by woodland and the occupancy rates of capital flows remained unchanged. The capital stock had been used by grassland and water, and the use ratios of stock-flows increased gradually. The development of Shenyang was in an unsustainable state. Coordinating the relationship between natural capital stock consumption and the utilization of stock-flows was one of the key ways to realize the sustainable development of Shenyang. Developing new resource, rationally planning the land and improving land utilization should be to reduce the consumption of natural capi-tal, at the same time, the protection of ecological environment should be to achieve sustainable development.
