基于我国城市防洪体系安全评价的指标体系及其等级标准,提出了一种基于小样本的最小二乘支持向量机(LS-SVM)的城市防洪体系安全综合评价模型。在柳州市防洪体系的实例应用结果表明,该模型能较好地对城市防洪体系进行综合评价,评价结果符合客观实际。
Based on the index system and grade standard of safety evaluation of urban flood control system in our country, a comprehensive safety evaluation model of urban flood control system based on LS-SVM with small sample is proposed. The application example of the flood control system in Liuzhou City shows that the model can comprehensively evaluate the urban flood control system and the evaluation results are in line with the objective reality.
