摘　　要：采用指标承载度模型法对辽宁省100个区县水环境承载力现状进行评价,但确定各项指标的分级标准时发现,原本的分级规则计算承载度的准确性有待提高。改进分级规则,采用两段式的分级标准来确定各项指标的承载度,可以更准确地表现评价对象承载力的真实水平。The indicator carrying capacity model was used to evaluate the current status of water environmental carrying capacity in 100 districts and counties in Liaoning Province.However,when determining the classification standards for each indicator,it was found that the accuracy of the original classification rules for calculating carrying capacity needs to be improved.By improving the classification rules and using a two-stage classification standard to determine the carrying capacity of each indicator,the real level of carrying capacity of the evaluation object can be more accurately represented.
