We design it by calculating two indicators, namely, footprint size and depth. perform quantitative research sustainable development. Based our results, from 2010 2020, per capita carrying capacity generally displayed varying rising trend; depth has been maintained at 1.1364 gha/cap, is clear constantly exceeded capacity, which means Gansu Province’s economic was in deficit. these findings, offer sound recommendations for environment’s Province.
