Abstract: Natural capital is the basis for human survival and sustainable development, which has received wide attention. In this study, the threedimensional ecological footprint extension model was used to estimate footprint size, footprint depth, and ecological carrying capacity in 2000, 2004, 2008, 2012 and 2016 in Zhejiang Province, to reflect the temporal dynamics of natural capital. From 2000 to 2016, the per capita ecological footprint of Zhejiang Province increased first and then decreased. In 2012, it reached a peak of 2.7950 hm²·cap^-1. Zhejiang Province was in a state of serious ecological deficit. Under the trend of increasing contradiction between supply and demand of natural resources, footprint depth in Zhejiang Province dropped from 8.2144 in 2012 to 8.1696 in 2016, providing a development strategy for mitigating ecological pressure by exploring energysaving technologies and seeking alternative energy sources. The overdraft of natural capital in Zhejiang Province was mainly on cropland and grassland, and the consumption of whose stocks continued to increase. Our results can enrich the evaluation method of natural capital and provide reference for accelerating ecological civilization system reform and building a Beautiful China.
