摘  要：
基于2008—2014年抚仙湖5个监测站的水质监测资料,开展水体污染程度评价,并分析各水质指标的变化特征,结果表明:2008—2014年抚仙湖各监测站水体综合污染指数均呈先上升后下降的趋势,汛期水体污染指数明显高于非汛期和全年平均,且在空间上呈现出北高南低的趋势。抚仙湖总体水质为I类水,但总磷和总氮浓度的变化较为明显,其中总氮浓度上升的趋势较为显著;在月际变化方面,各指标浓度最高值出现的时间相对于降水最多月份(6—8月)滞后1个月,即7—9月,而最低值出现时间与降水最少月(12月至次年2月)基本吻合。

摘  要：
Based on water quality monitoring data of Fuxian Lake in 5 stations from 2008 to 2014,the pollution degree was evaluated and variation characteristics of each index were analyzed. The results showed that the water comprehensive pollution index of each monitoring station presented the trend of first increasing and then decreasing,the water pollution index in flood season was significantly higher than that in nonflood season and annual average,and showed a upward trend from the south to the north of Fuxian Lake. The overall water quality was I class,however,the change of TP and TN concentration was significant,the rising trend of TN concentration was the most significant; the time of the highest value of each indicator concentration was lag a month with the maximum precipitation month( June to August),namely July to September,the lowest value occurred when the precipitation is the least( December to February of the following year).
