摘　　要：根据2007～2011年的实测数据,对洱海总磷、总氮的时空变化规律进行了分析。分析表明洱海全湖总磷、总氮浓度变化规律为:丰水期>平水期>枯水期;年际间呈跳跃式变化;洱海四周沿岸高于洱海中部。对上述规律的原因进行了简要分析,并提出了相应的对策措施。According to the monitoring data of 2007 - 2011, the temporal and spatial variation of total nitrogen and total phosphorus in Lake Erhai are analyzed. It shows that the concentration change of the total phosphorus and total nitrogen is as follows ： rainy season 〉 average season 〉 dry season ; and the yearly change is in leaps and bounds. The concentration of the lake shore is higher than the central lake. The causes of the change are briefly studied and the countermeasures are proposed.
