摘要
【目的】计算重庆市2000和2010年的生态足迹和生态承载力,研究2000—2010年土地利用类型转换情况,分析生态承载力变化原因,通过生态赤字/盈余分析重庆市生态可持续发展状况。【方法】引入水资源账户和环境负荷并结合重庆市实际调整均衡因子和产量因子改进传统生态足迹模型。【结果】2000—2010年除水资源用地、污染吸纳地和草地的生态足迹在降低,总生态足迹和其他生态足迹在升高;生态承载力方面除耕地降低外,总生态承载力和其他各类用地生态承载力在升高,原因是2000—2010年间耕地转为其他类型用地。【结论】林地、建设用地和水资源处于生态盈余状态,耕地、草地、水域处于生态超载状态,重庆市总体上处于生态超载状态。
[Purposes]To calculation the ecological footprint and ecological carrying capacity of Chongqing city in 2000 and 2010,study the land use type conversion in 2000—2010,analysis the change cause of ecological carrying capacity and analysis the ecological sustainable development in Chongqing by ecological deficit/surplus.[Methods]Improve the traditional ecological footprint model by introducing the water resources accounts and environmental loads,and adjust the equilibrium factor and yield factor combined with the actual situations in Chongqing.[Findings]The results showed that 2000—2010 in addition to water resource use,pollution from ecological footprint and grassland in the reduction of the total ecological footprint and ecological footprint in increased;the ecological carrying capacity in farmland decrease,the total ecological carrying capacity and other types of land ecological carrying capacity on the rise,the reason is that the 10 years of farmland to other the type of land.[Conclusions]The present study showed that forest land,construction land and water resources are in a state of ecological surplus,cultivated land,but grassland and water area are in a state of ecological overload,overall,Chongqing is in a state of ecological overload.
