摘　　要：分析水库溃坝风险的综合影响,诊断识别溃坝环境影响的脆弱性指标。在集对分析原理的基础上,通过改进五元隶属度函数的构造方式,结合五元引力减法集对势及级别特征值,构建了基于五元引力减法集对势的溃坝环境影响评价模型,应用于沙河集水库并进行分析和论证。结果表明,该模型在水库溃坝环境影响中评价结果相比其他评价方法更为合理可靠,且评价结果是一实数值,具有一定的精确性。对评价指标进行诊断识别,其中河道形态、植被覆盖、土壤环境、污染工业4个评价指标是影响沙河集水库溃坝环境评价结果的主要因素。五元引力减法集对势的溃坝环境影响评价模型可为水库溃坝环境影响评价提供一种新的思路。The comprehensive impact of reservoir dam failure risk is analyzed,and the vulnerability indicators for diagnosing and identifying the environmental impact of dam failure are diagnosed.On the basis of the principle of set pair analysis,by improving the construction method of five-element affiliation function,combining the five-element gravitational subtraction set pair potential and level eigenvalues,we constructed a dam failure environmental impact evaluation model based on the five-element gravitational subtraction set pair potential,which was applied to analyze and demonstrate Shaheji Reservoir.The results show that the evaluation results of the model in the environmental impact of dam failure in reservoirs are more reasonable and reliable compared with other evaluation methods,and the evaluation results are a real value with certain accuracy.The evaluation indexes are diagnosed and recognized,in which the evaluation indexes of river morphology,vegetation cover,soil environment,and polluted industry are the main factors affecting the results of the environmental evaluation of dam breaching in Shaheji Reservoir.The dam-break environmental impact evaluation model of five-element gravitational subtraction set pair potential can provide a new idea for the environmental impact evaluation of reservoir dam-break.
