摘要
文章通过分析位于江苏省7个河流、湖库水质自动站2017年的自动监测数据,发现在4—10月,水生植物生长茂盛期间,生长水生植物断面的溶解氧质量浓度会随着时间点发生规律性变化,且溶解氧质量浓度昼均值大于夜均值,造成这类现象的主要原因是由于水生植物的光合作用及呼吸作用。因此,在水生植物比较茂盛的断面考核溶解氧时,需要考虑水生植物对溶解氧质量浓度的影响。
By analyzing the automatic monitoring data of 7 rivers and lakes water quality automatic stations in Jiangsu Province in 2017,it is found that during April to October,the dissolved oxygen mass concentration of the growing aquatic plants will occur with time during the lush aquatic plants in this paper.The regularity changes,and the mean value of dissolved oxygen mass concentration is greater than the night average.The main reason for these phenomena is that the photosynthesis and respiration of aquatic plants.Therefore,the effect of aquatic plants on dissolved oxygen mass concentration needs to be considered when assessing dissolved oxygen in a relatively lush section of aquatic plants.
