【摘要】：利用水資源生態(tài)足跡模型對(duì)河南省2005-2014年的水資源生態(tài)足跡、生態(tài)承載力進(jìn)行了分析。在考慮黃河客水情況下的結(jié)果表明:12005-2014年間河南省總水資源生態(tài)足跡呈現(xiàn)不斷上升趨勢(shì),農(nóng)業(yè)用水居于主導(dǎo)地位,累積貢獻(xiàn)率為576.1%;2水資源生態(tài)承載力與降雨量之間有密切的聯(lián)系,相關(guān)系數(shù)為0.925 5;310年間均出現(xiàn)不同程度的生態(tài)赤字,水資源負(fù)載指數(shù)也全為Ⅰ,水資源利用前景不容樂(lè)觀;4人均水資源生態(tài)足跡相對(duì)較低,一直在0.35~0.42 hm2之間波動(dòng);萬(wàn)元GDP水資源生態(tài)足跡逐年下降,水資源的利用效率不斷提高,但河南省總體水資源利用處于不安全狀態(tài)。
[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，
