采集了2010—2014年洱海中粪大肠菌群监测数据，以 MPN （最可能数）值分析出粪大肠菌群的月份、季度、年度、不同断面的变化趋势，得出月均值和季均值高的月份与丰水期有关，低的月份与枯水期有关；2010年 MPN年均值最高，2011年最低；监测断面 MPN均值总体上北部＞南部＞中部（湖心）。对这些变化趋势进行了原因分析，提出相关建议和措施。
採集瞭2010—2014年洱海中糞大腸菌群鑑測數據，以 MPN （最可能數）值分析齣糞大腸菌群的月份、季度、年度、不同斷麵的變化趨勢，得齣月均值和季均值高的月份與豐水期有關，低的月份與枯水期有關；2010年 MPN年均值最高，2011年最低；鑑測斷麵 MPN均值總體上北部＞南部＞中部（湖心）。對這些變化趨勢進行瞭原因分析，提齣相關建議和措施。

The monitoring data of fecal coliform from the year of 2010 to 2014 in Erhai Lake were used to analyze its monthly,seasonally,and yearly changes in different monitoring sites based upon the MPN value.The results showed that the high monthly average and seasonally average had close relationship with high flow period.The low average was correlated to low water period.The highest yearly MPN value occurred in 2010 and the lowest was in 2011.The average MPN in the north was higher than that in the south and the center.The drivers of these changes were explored.The countermeasures were put forward on fecal coliform control.
