| 摘 要： | 康平县位于我国最重要的一条生态过渡带上,生态环境异常敏感而脆弱。为全面了解康平县的生态环境和可持续发展状况,进一步改善康平县的生态环境,运用生态足迹理论对康平县2008年生态足迹和生态承载力进行对比分析,结果表明,2008年康平县人均生态足迹为3.227 8hm2,人均生态承载力为1.458 5hm2,人均生态赤字为1.769 3hm2。说明康平县当前经济社会处于不可持续发展状态,显示了当前人地关系紧张和生态形势的严峻性,生态安全受到威胁。康平县生态赤字的主要原因为农产品过度消耗,需通过发展生态产业,调节能源结构,提高生态承载力,降低生态足迹,实现康平县的可持续发展。

| 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. |
