Analysis of ecological carrying capacity and ecological footprint of Zhuhai city from 1993 to 2013

Applying the theory and method of ecological footprint，the paper analyzed the eco-capacity，ecofootprint and eco-surplus of Zhuhai City from 1993 to 2013. The results showed that the city's eco-capacity fluctuated greatly during the 20 years，which is a“saddle shape”curve that is rose first，next dropped and then rebounded. As the population continues to increase，the per capita eco-capacity shows a trend of unilateral decline，which has dropped by 44.76% in 20 years. However，the eco-footprint of Zhuhai from 1993 to 2013 increased frist and then decreased，which reached a maximum value of 752 688.0249 hm2 in 2003.It decreased to 630 081.1731 hm2 in 2013 and was a trend of continuously decreased. Overall， the eco-footprint of Zhuhai has been greater than that of ecological carrying capacity from 1993 to 2013， Although it showed a mild deficit， there is a tendency of narrowing It is predicted that Zhuhai will eliminate the eco-deficit and get a balance in 2040.
