As a new scientific concept in recent years,water ecological carrying capacity is helpful to control water environmental pollution and restore water ecosystems through the assessment ofwater ecological carrying capacity.This paper clarifies the concept and significance of water ecological carrying capacity,summarizes and analyzes several research methods widely used at home and abroad,compares and analyzes the research methods and their advantages and disadvantages,and analyzes the weight calculation of water ecological carrying capacity evaluation indicators.By combining the entropy weight method and analytic hierarchy method to calculate the weight of water ecological carrying capacity index,it can not only reflect the researcher's judgment on the importance ofthe index but also objectively reflect the change difference of the data,making the results more scientific and accurate,in order to provide theoretical support for the method research and index weight calculation of water ecological carrying capacity.
