Abstract: |
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. |
