【摘要】：以南水北调中线工程渠首南阳市为例,采用水资源生态足迹法分析了南阳市2006~2013年水资源基本情况,进而评价了南阳市水资源可持续利用状况。结果表明,在2006~2013年间,南阳市人均水资源生态足迹和万元GDP生态足迹总体呈下降趋势,二者分别下降了26.6%和64.71%,且人均万元GDP耗水量低于全国平均水平20%左右,说明通过近年来的综合治理,在提高用水效率方面已取得了较显著的成效;南阳市连续多年出现水资源生态赤字或接近赤字,2013年人均水资源生态赤字已达0.122hm2,水资源总体上还处于不可持续使用状态。
[Abstract]:Taking Nanyang City as an example, the basic situation of water resources in Nanyang City from 2006 to 2013 was analyzed by using the method of ecological footprint of water resources. The results showed that the ecological footprint of per capita water resources and the ecological footprint of GDP per capita in Nanyang City were on the whole decreasing from 2006 to 2013. The two decreased by 26.6% and 64.71 respectively, and the per capita GDP water consumption was lower than the national average level of about 20%, indicating that the comprehensive management in recent years. Remarkable results have been achieved in improving the efficiency of water use. In 2013, the ecological deficit of water resources per capita has reached 0.122 hm ~ 2 in Nanyang, and the water resources are still in a state of unsustainable use.
