摘　　要：运用Kendall秩次相关检验法、有序聚类分析法、游程检验法和方差谱密度图法等时间序列的分析方法对南四湖上级湖溶解氧DO等水质指标序列进行分析,利用2008年~2013年监测数据,对其分别进行了趋势成分及跳跃成分的识别和检验、周期成分的识别和提取;并用2014年监测数据对组成成分的识别结果进行检验,据此分析了DO指标序列的变化规律,预测DO指标的变化趋势。结果表明,南四湖上级湖的DO指标存在以年为周期的周期成分,虽均达到III类水质标准,但其量有减小趋势;在南四湖治理中,夏季应采取相应的防治措施。The Kendall rank correlation method, the ordered clustering analysis method, the run test and the variance spectrum density diagram method are applied to the analysis of Nansi upper lake＇s DO index sequences from 2008 to 2013, and the trend components, jump components and periodic components of these sequences are respectively identified. Based on the DO monitoring data of 2014, the results of the component identification are tested. According to these results, the change rules of DO index sequences are summarized and the change trend of DO index is forecasted. The results show that the Nansi upper lake＇s DO index sequence exhibits remarkable seasonal variation which had a period of one year. Although current DO is to class III water quality standard, but its content has a decreasing trend. Taking corresponding prevention measures in summer should be paid attention in the management of Nansi Lake.
