摘　　要：根据水资源安全评价指标确立的原则,建立全面合理的水资源安全评价指标体系。在面板数据分析领域下,提出基于中心点三角白化权函数的水资源安全灰色评估模型,根据白化权函数值离差最大化原理改进指标权重的确定方法,并利用灰色聚类时间系数来表征面板数据的时间维度,反映水资源安全评价的时间特征和评价指标的重要程度。结合青海省8个行政分区的水资源安全评价结果,验证该模型合理、可行。According to the principle of setting up the index of water resources safety assessment,the reasonable and comprehensive index system of water resources safety assessment is established. In the field of panel data analysis,a grey evaluation model of water resources security is proposed based on the center triangular whitenization weight function. The method for determining the index weights is improved according to the principle of maximizing deviations of whitenization weight function. By using the grey time clustering coefficient to characterize the temporal dimension of panel data,the temporal characteristics of water safety assessment and the importance degree of the evaluation index are reflected. According to the water resources security evaluation results of 8 administrative regions in Qinghai Province,the reasonable and feasible of the model is verified.
