摘　　要：中国目前尚未形成完善的湖泊营养物基准指标优选方法,导致湖泊营养物基准的建立在指标选取上存在较多困难。简单介绍了美国环境保护署利用压力响应关系法选择湖泊营养物基准指标的过程,并以此为基础,根据中国湖泊富营养化的实际情况加以改进,提出了适合中国的湖泊营养物基准指标优选方法。还以某流域湖泊为例,探讨了在探索性数据分析过程中营养物基准指标的选取方法。China has not formed the complete optimization method for selecting lake nutrient criteria index, so the establishment of the lake nutrient criteria has faced many difficulties. The United States Environmental Protection Agency applied stressor-response relationships to derive nutrient criteria indicator, the procedure was briefly described in this paper. According to the actual situation of lake eutrophication in China, a modified nutrient criteria indicator system was proposed. Based on a survey data of a certain lake basin, the process of exploratory data analysis for selecting nutrient indicators was performed,and nutrient criterion indicators was determined ultimately.
