摘　　要：将KL散度与TOPSIS结合优化了传统TOPSIS水质评价模型,为了使评价结果直观、可视化,将优化后的TOPSIS模型与哈斯图技术耦合,建立了基于KL散度的TOPSIS与哈斯图耦合的水质评价模型。北京某厂区周边村落地下水水样的实例分析表明,建立的水质评价模型的评价结果与实际情况相符,证明了该评价模型的有效性及合理性;最终评价结果以图的形式展现出来,可视化更强;相对于传统TOPSIS水质评价模型评价结果更精细化,且有利于提高评价结果的精确度。The traditional TOPSIS water quality evaluation model was optimized by combining KL(Kullback⁃Leibler)divergence and TOP⁃SIS.In order to make the evaluation results intuitive and visual,the optimized TOPSIS model was coupled with the Hasplot technology and a coupling based on KL divergence and TOPSIS established water quality evaluation model.An example analysis of groundwater samples from a village around a plant in Beijing shows that the evaluation results of the established water quality evaluation model are consistent with the ac⁃tual situation,proving the validity and rationality of the evaluation model;the final evaluation results are displayed in the form of a graph and visualized stronger;Compared with the traditional TOPSIS water quality evaluation model,the evaluation results are more refined and it is helpful to improve the accuracy of the evaluation results.
