摘　　要：地表水是可利用水资源的重要组成部分,针对当前地表水资源突发性污染风险评价方法对于水流方向以及水质分析能力较差,导致评价结果与实测结果相差较大的问题,设计新型地表水资源突发性污染风险评价方法。选用一维水量水质模型,完成地表水资源突发性污染模拟分析。构建污染风险评价指标体系,计算各指标熵值,确定评价指标权重。构建地表水资源突发性污染风险评价模型,得到突发性污染风险评价等级。进行实验对此方法使用效果加以分析。实验结果表明,此方法使用后所得评价等级与实测结果一致,可见此方法评价结果可靠性较高。Surface water is an important part of water resources. The poor analysis ability of current risk assessment methods of sudden pollution of surface water resources for flow direction and water quality resulted in a large difference between the assessment results and the measured results. A new surface water resources sudden pollution risk assessment method is designed. One dimensional water quantity and quality model is used to simulate and analyze the sudden pollution of surface water resources. The paper built the pollution risk evaluation index system, calculated the entropy of each index, and determined the weight of the evaluation index. The risk assessment model of sudden pollution of surface water resources is established, and the risk assessment grade of sudden pollution is obtained. Experiments were conducted to analyze the effect of this method. The experimental results show that the evaluation grade obtained by this method is consistent with the measured results, which shows that this method has high reliability.
