摘　　要：中国环境科学研究院于2009年11月和2010年3月在重庆长寿湖全湖采样,通过测量118个(11月)和31个(3月)水样的总磷浓度,揭示长寿湖水体磷的空间分布及变化规律。研究表明:11月份长寿湖水体总磷平均浓度较低,水质大都处于Ⅳ类;3月份长寿湖水体总磷平均浓度较高,水质处于Ⅳ～劣Ⅴ类之间;3月份长寿湖水体总磷浓度要比11月份普遍偏大,平均水质也要比11月份低1个等级。这主要和3月温度明显高于11月,春节期间上游火炮纸生产加剧以及沿湖精养鱼塘放水等原因有关。118(November) and 31(March) water samples were collected from entire Lake Changshou in November,2009 and March 2010. Reveal the Spatial distribution and variation of phosphor in water of Lake Changshou by determine the total phosphor(TP) concentration of the samples. The results show that:the average TP concentration of the samples is low in November,at Class Ⅳ;the average TP concentration of the samples is high in March,between Class Ⅳ～bad Ⅴ.The average water class in March is a level lower than in November. The main reason is that the temperature in March is higher,and Production and discharge of fireworks during Spring Festival and increasing pollution of life.
