Abstract: To explore the changing characteristics of the ecological carrying capacity and figure out the key influencing factors of sustainable development of the Renhuai City, the per capita ecological footprint, per capita ecological carrying biocapacity and ecological surplus/deficit from 2010 to 2018 were analyzed based on the ecological footprint model. Furthermore, four key indexes, including ecological footprint index, ecological stress index, corresponding quotiety of ecological and GDP's ecological footprint, and six factors were applied to study the sustainable development status and influencing factors of Renhuai City. Results show that the Renhuai City has been in status of ecological deficit. Both the per capita ecological footprint and the per capita ecological carrying capacity presented a similar trend of decreasing first and then increasing. The per capita ecological footprint increased from 1.5 hm2 to 1.8 hm2, with an increase of 20% during research period. The per capita ecological carrying capacity increased by 14.89%, from 0.94 hm2 to 1.08 hm2; the per capita ecological footprint and per capita ecological carrying capacity of the Renhuai City were mainly contributed by cultivated land and woodland, which accounting for 81% of the per capita ecological footprint and 79% of the per capita ecological carrying capacity, respectively. The ecological footprint index was between -76.96% and -59.22%, and the ecological pressure index was ranged from 1.59 to 1.77, as in view of the relevant evaluation standards, the Renhuai City's ecological footprint index and ecological stress index was in the status of 3rd grade and the 5th grade, suggesting there exists great challenges in regional sustainable development. In addition, the main driving factors impeding the Renhuai City's ecological footprint were population size, featured industries, and pollutants emissions. These results of the research are helpful to discover the internal connection between the development of featured industries in Renhuai City and the ecological footprint, and can provide theoretical basis for the sustainable development patten of similar areas.
