以陕西省不同地貌类型区分布的9个典型县域为研究对象,选取人均水资源可利用量、人均水资源占有量、单位GDP用水量、水资源开发利用率、单位耕地水资源量、单位面积水资源量、灌溉率等7项评价指标,采用模糊识别理论模型,计算得到水资源承载能力(WRCC)的相对隶属度和影响因子的贡献率;在考虑主观权重条件下,基于互补理论的二元对比方法确定主观权重,通过级别特征值计算得到典型县域WRCC级别。结果表明,陕南地区4个县的水资源充足,其水资源与经济发展较为协调,可开发潜力很大;关中地区3个县水资源已严重超载,需要采取措施进行人工干预;陕北地区靖边和安塞县水资源不富足。
以陝西省不同地貌類型區分佈的9箇典型縣域為研究對象,選取人均水資源可利用量、人均水資源佔有量、單位GDP用水量、水資源開髮利用率、單位耕地水資源量、單位麵積水資源量、灌溉率等7項評價指標,採用模糊識彆理論模型,計算得到水資源承載能力(WRCC)的相對隸屬度和影響因子的貢獻率;在攷慮主觀權重條件下,基于互補理論的二元對比方法確定主觀權重,通過級彆特徵值計算得到典型縣域WRCC級彆。結果錶明,陝南地區4箇縣的水資源充足,其水資源與經濟髮展較為協調,可開髮潛力很大;關中地區3箇縣水資源已嚴重超載,需要採取措施進行人工榦預;陝北地區靖邊和安塞縣水資源不富足。

In this paper,7 elevation indexes include per-capita availability quantity of the water resources,water resources ownership per capita,water consumption per unit GDP,utilization rate of water resources,water resources quantity per capita arable land,water resources quantity per unit area,irrigation rate are selected .The fuzzy recognition theory (FRT)model is adopted for calculating the contribution ration and relative membership of selected impact factors of regional water resources carrying capacity (WRCC).Subsequently,based on the complementary binary comparison method,the subjective weights are obtained .Whilst,the WRCC characteristic value level of sample counties in Shaanxi province are deducted .The result shows that:water resources in Southern Shaanxi such as Shiquan, Shangnan, Nanzheng and Zhenping county are adequate relatively,which means a more coordinated relationship between social eco-nomic development and WRCC;water resources in Guanzhong region such as Wugong,Jingyang and Qishan county have been severely overloaded,measures should be taken to carry out human intervention;and water resources in Northern Shaanxi such as Jingbian and Ansai county are still not rich .FRT-based WRCC fuzzy assessment method reflects the water resources conditions of sample counties of Shaanxi Province .
