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.
利用改进的三维生态足迹模型分析了1995年至2014年沈阳市的自然资本趋势。结果表明，1995年至2014年，沈阳市人均生态承载力总体在窄幅范围内波动；人均生态足迹、生态赤字、足迹规模和人均足迹深度呈波浪式上升。足迹规模和深度的变化率趋于逐渐稳定。耕地自然资本利用方式从2004年的资本流量转变为资本存量，资本存量取代资本流量成为区域耕地自然资源需求的满足来源，存量流量利用比例逐渐增加。资本流量被林地利用，资本流量占用率保持不变。资本存量被草地和水域利用，存量流量利用比例逐渐增加。沈阳市的发展处于不可持续状态。协调自然资本存量消耗与存量流量利用之间的关系是实现沈阳市可持续发展的关键途径之一。开发新资源、合理规划土地和提高土地利用率应减少自然资本的消耗，同时，保护生态环境应实现可持续发展。
