利用水资源生态足迹模型对河南省2005-2014年的水资源生态足迹、生态承载力进行了分析。在考虑黄河客水情况下的结果表明:12005-2014年间河南省总水资源生态足迹呈现不断上升趋势,农业用水居于主导地位,累积贡献率为576.1%;2水资源生态承载力与降雨量之间有密切的联系,相关系数为0.925 5;310年间均出现不同程度的生态赤字,水资源负载指数也全为Ⅰ,水资源利用前景不容乐观;4人均水资源生态足迹相对较低,一直在0.35~0.42 hm2之间波动;万元GDP水资源生态足迹逐年下降,水资源的利用效率不断提高,但河南省总体水资源利用处于不安全状态。
According to basic calculation model of water resources ecological footprint, the water resources ecological footprint and ecological carrying capacity in the years from 2005 to 2014 in Henan Province are analyzed. In the case of considering the Yellow River Diversion, the results are as follows : ① during the period of 2005 to 2014, the agricultural water ecological footprint is rising steadily, it holds a dominant position in the total water resources ecological footprint, and the cumulative contribution is 576.1%. ② there is a positive correlation between water resources ecological carrying capacity and annual rainfall, and the correlation coefficient is 0.925 5. ③ there is different levels of eco- logical deficit in the ten years, the load index of water resources is all I , and the water resource utilization prospect is not optimistic. ④ With a relatively low per capita water resources ecological footprint, it has a slight fluctuation from 0.35 to 0.42. The water resources ecologi- cal footprint of ten thousand yuan GDP is decreased year by year, showing that the water resource efficiency is increasing. But the water re- source utilization is still insecure on the whole.
