【摘要】：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。
[Abstract]:The ecological footprint and ecological carrying capacity of water resources in Henan Province from 2005 to 2014 were analyzed by using the ecological footprint model of water resources. The results show that the ecological footprint of the total water resources in Henan Province has been increasing from 2005 to 2014, the agricultural water consumption is dominant, and the cumulative contribution rate is 576.1%, which is closely related to the rainfall and ecological carrying capacity of water resources. The correlation coefficient was 0.925 ~ 310 years, and the water resources load index was all 鈪，
