Evaluation and improvement pathways of water resources utilization in Henan Province
摘要
Abstract
Taking the 18 prefecture-level cities of Henan Province as the evaluation units,we constructed a comprehensive index system across four dimensions(resource utilization efficiency,economic benefit,social benefit,and ecological benefit).The entropy weight method,TOPSIS model,and obstacle degree model were combined to evaluate water resources utilization efficiency and pinpoint the critical obstacle factors.The aim is to provide a scientific basis for formulating differentiated water resources management strategies and addressing the contradiction between water supply and demand.The results indicate that the overall water resources utilization efficiency in Henan Province is relatively high,with the agricultural water use efficiency coefficient reaching 5.59 kg/m3,which is significantly higher than the national aver-age.However,pronounced regional disparities exist,presenting a spatial pattern of"high in the central and western regions,low in the northeast and southwest".Moreover,the province's water resources de-velopment and utilization rate(43.78%)has already exceeded the international alert line.Cities such as Zhengzhou and Jiyuan are primarily constrained by resource efficiency indicators(e.g.,agricultural GDP per unit water use,water supply modulus),while agriculture-dominated cities like Zhoukou and Shan-gqiu are significantly affected by excessively high agricultural water use proportions and relatively low per capita GDP.Inadequate allocation of ecological water use emerges as a common bottleneck across many regions,and the water resources utilization efficiency and economic development level exhibit unbalanced spatial coupling characteristics.To enhance water resources utilization efficiency,Henan Province needs to implement differentiated and precise management measures.Specifically,areas with high development intensity should strengthen total volume control and improve utilization efficiency;agriculture-dominated areas should focus on optimizing water use structure and promoting water saving technologies;and the en-tire province should reinforce ecological water security and market oriented mechanisms.These efforts are intended to promote the sustainable use of water resources and the coordinated high quality development of the economy.关键词
