The invention relates to the technical field of pollution assessment, and provides a water environment heavy metal pollution comprehensive evaluation method and system.The method comprises the steps that a heavy metal pollution assessment index system is constructed, heavy metal pollution data in a water environment are collected according to the constructed index system, the collected data are preprocessed, and the preprocessed data are obtained; data of different indexes are unified into the same dimension and range, the weight of each index is determined according to the importance and contribution degree of the indexes, a comprehensive evaluation model is constructed according to the determined weight and the standardized data, and a final evaluation result is used as output. And finally, explaining and analyzing evaluation results obtained by the comprehensive evaluation model, and dividing the evaluation results into different grades to visually represent the heavy metal pollution degree of the water en
