梁子湖区生态足迹与生态承载力空间动态变化分析

Dynamics of Ecological Footprints and Ecological Capacity in Liangzi Lake District

摘要: 利用生态足迹理论，计算分析了梁子湖区2007~2011年5年间生态足迹变化，结果表明，梁子湖区人均生态足迹由2007年的1.73517 hm2上升到2011年的3.03992 hm2，人均生态承载力由2007年的0.54175 hm2上升到2011年的0.62625 hm2，由于对资源的需求量大于供给量，所以梁子湖区生态赤字也在逐年提高。梁子湖区处于不可持续发展的状态，特别是对于水资源的生态赤字持续增长。梁子湖区万元GDP有上升的趋势，说明梁子湖区资源利用率有所下降。同时对梁子湖内部生态足迹做了空间分析，也提出了减少区域生态赤字的措施。

Abstract: The analysis on the dynamic changes of ecological footprint and ecological capacity in Liangzi Lake District showed that in 2007-2011, the ecological footprint per capita in the district increased form 1.735171763 hm2 to 3.039921491 hm2, while the ecological capacity per capital increased form 0.541747253 hm2 to 0.626252988 hm2. Be- cause the demand for resources is greater than the supply, ecological deficit increased year by year. Liangzi Lake Dis- trict is in a state of unsustainable development, especially for the sustainable growth of the ecological deficit of water resources. As a whole, the ecological footprint per ten thousand yuan GDP increased in the five years, indicating that the resources efficiency in the district was descended gradually. Based on the present situation, we made an internal space analysis and put forward some measures for reducing the ecological deficit.
