摘要
扬州地处江苏中部,境内河湖广布,水系发达,淮河、长江均从境内穿过。随着城市经济建设的快速发展,扬州的河流、湖泊都受到了不同程度的污染。本次基于2009~2013年扬州市高邮湖(郭集)、万福闸下、仪征水厂、四水厂(瓜洲)四个站点的溶解氧浓度实时监测数据,分析了扬州市典型水体的时空分布特征。并探讨了影响水体溶解氧动态分布特征的影响因子,得出溶解氧浓度的影响因子为高锰酸盐指数和氨氮,并分别总结出不同测站的回归方程。多因素相关分析结果显示,高锰酸盐指数、氨氮的含量与水体中的溶解氧浓度呈显著性负相关关系。
Yangzhou, which contains large areas of rivers and lakes, is located in the middle of Jiangsu. Huaihe River and Yangtze River go through the territory of Yangzhou. With the rapid development of urban economy, the rivers and lakes have been polluted in varying degrees. Based on the real-time monitoring data of the dissolved oxygen in four sites, Gaoyou Lake （Guoji）, under Wanfu Gate, Yizheng Waterworks, The Fourth Waterworks （Guazhou） during 2009 to 2013, the spatial and temporal distribution characteristics of typical water of Yangzhou are analyzed. The impact factors which influenced the dynamic distribution characteristics of the dissolved oxygen are discussed. The results show that the impact factors are potassium permanganate and ammonia nitrogen. Additionally, the different regression equations in four sites are calculated. The results of multiple linear regression showed that the dissolved oxygen was significant negative correlation with potassium permanganate and ammonia nitrogen.
