A Study of Ecological Carrying Capacity Based on the Ecological Footprint Model:a Case Study of Kangping County

Abstract

Abstract: Kangping county is situated at the most important ecological boundary in China,which is an extremely ecological sensitive zone.In this paper,based on the model of ecological footprint,ecological footprint demand of Kangping county,ecological carrying capacity and ecological deficit or surplus were calculated.The comparative analysis of ecological footprint and ecological carrying capacity was made by ecological footprint method in order to overall understand the ecological environmental situation,assess the sustainable development status of Kangping County in 2008 and analyze the main reasons of ecological pressure.The results showed that the per capita ecological footprint,per capita ecological carrying capacity and per capita ecological deficit were 3.227 9 hm²,1.458 5 hm² and 1.769 4 hm²,respectively in 2008.Based on the analysis according to the computation,it has been indicated that the humanity factors surpass the ecology capacity seriously,the ecological carrying capacity cannot satisfy the ecological footprint of the demand,and the social and economic development is in an unsustainable state.The development ability of Kangping County is in the trend of rising at present. However,the ecological carrying capacity has not already been able to satisfy the need of economic development,while economic growth now is based on the depletion of natural resources.Consequently,the relevant measures must be taken to decrease the ecological footprint and to enhance the capacity of sustainable development.To reduce per capita ecological footprint and enhance per capita ecological carrying capacity,it is recommended that resources utility be increased,styles of production and life improved,productivity increased and ecosystem conserved.For promoting regional development,resources exploitation should be combined with environment conservation,ecological industries developed and regional ecological economic assessment system reconstructed.

Key words: ecological footprint, ecological carrying capacity, ecological deficit, Kangping County
