【摘要】：采用水资源生态足迹模型,定量计算和分析了广西2008年-2012年人均水资源生态足迹、水资源生态承载力、水资源生态盈余,并对比分析广西14个城市的人均水资源生态足迹、生态承载力情况。结果显示:(1)广西人均水资源生态足迹指数近五年内没有大幅度的变化,比较稳定保持在1.06hm2/人附近,各年人均水资源生态足迹水平高低依次为2010=2011201220082009;而人均生态承载力指数变化较大,且均小于人均水资源生态足迹;(2)只有柳州市和防城港市存在水资源生态盈余,其他各市均存在水资源生态赤字,平均赤字0.56hm2/人。面对水资源生态赤字问题,广西需通过调整产业结构,优化水资源配置,实施水资源管理"三条红线"等措施,提高水资源生态承载力,减小生态赤字,以达到水资源可持续利用的目的。
[Abstract]:Based on the ecological footprint model of water resources, the ecological footprint of water resources per capita, ecological carrying capacity of water resources and ecological surplus of water resources were calculated and analyzed quantitatively in Guangxi from 2008 to 2012, and the ecological footprint of per capita water resources in 14 cities of Guangxi were compared and analyzed. Ecological carrying capacity. The results show that: (1) the per capita ecological footprint of water resources in Guangxi has not changed by a large margin in the past five years, and it is relatively stable in the vicinity of the 1.06hm2/ population, and the ecological footprint level of the per capita water resources in each year is in the order of 2010 / 201120122008 / 2009, while the per capita ecological carrying capacity index has a great change. (2) only Liuzhou and Fangchenggang have ecological surplus of water resources, other cities have ecological deficit of water resources and average deficit of 0.56hm2/. Facing the problem of water resources ecological deficit, Guangxi needs to improve the ecological carrying capacity of water resources and reduce the ecological deficit by adjusting the industrial structure, optimizing the allocation of water resources and implementing the "three red lines" of water resources management. In order to achieve the purpose of sustainable use of water resources.
