Abstract: In order to truly reflect the current state of the ecological footprint and ecological capacity of small towns,this paper synthetically analyzed the advantages and disadvantages of the models of International hectare,National hectare and Provincial hectare,finally choose the model of City hectare to calculate the ecological footprint and biological capacity of mianzhu,at the same time,the calorific value was introduced to localization of equilibrium factor and yield factor.Results showed that the equilibrium factor and yield factor with the models of International hectare and City hectare had a big difference.The final results were as follows:the per capita ecological footprint in mianzhu in 2014 was 0.402024 hm²,per ecological capacity was 0.283983 hm²,and the ecological deficit was 0.11804 hm².
