基于熵权TOPSIS的黄河流域甘肃段水资源承载力评价
Comprehensive Evaluation of Water Resources Carrying Capacity in the Gansu Section of the Yellow River Basin Based on Entropy-Weight-TOPSIS Model
摘要
Abstract
In order to assess the water resources carrying capacity of the Gansu section of the Yellow River Basin,this paper chose a set of 20 evaluation indicators initially,targeting four distinct secondary regions.Through an analytical process involving sensitivity and correlation as-sessments,seven indicators that exhibited low sensitivity and high correlation were pruned,culminating in a refined set of 13 indicators.These indicators were systematically organized into four sub-systems of water resources,societal factors,economic aspects,and ecological en-vironment.The composite scores were derived by integrating the entropy weight method with the TOPSIS model.Furthermore,a barrier factor diagnosis model was applied to evaluate the water resources carrying capacity across the four secondary regions.The findings reveal spatial variations in carrying capacity,with the area above Longyangxia station demonstrating the highest capacity,followed by the sections from Longyangxia station to Lanzhou and from Lanzhou to Hekouzhen station,and the lowest capacity observed in the section from Longmen to Sanmenxia station.In terms of temporal trends,barring the area above Longyangxia station,a steady rise in carrying capacity is observed in the remaining three regions.Key factors impeding the water resources carrying capacity in the Gansu section of the Yellow River Basin encom-pass per capita water availability,water production index,per capita water supply,population density,urbanization rate,and the rate of wa-ter usage for ecological environments.Strategic planning of water resources distribution,restructuring water consumption patterns,and syn-chronizing water resources carrying capacity with economic growth are instrumental in enhancing and sustaining the carrying capacity of the Gansu section of the Yellow River Basin.关键词
