秀山县钟灵水库湖水中磷形态分布特征

摘要

To detail more about the distribution characteristics of phosphorus species in surface water of Zhongling reservoir, five different points were used to monitor the content of phosphorus in different forms of lake water.The relationship between the phosphorus content in each sampling point was also analyzed.The results showed that the content of TP, DTP and DP were 0.015～0.027mg/L,0.010～0.020mg/L and 0.006～0.013mg/L respectively in the Zhongling reservoir.The TP in the lake was mainly in the form of dissolved phosphorus (DTP) while DTP was mainly in the main form of DP.The concentrations of TP were relatively high in two and three points, indicating that the regional phosphorus was strongly influenced by the environment in these areas.%为详细了解钟灵水库表层湖水中磷形态的分布特征,选取5个点位监测了湖水中不同形态磷的含量,分析了各采样点磷形态含量之间的关系.研究结果表明:TP、DTP和DP的含量范围分别为0.015～0.027 mg/L、0.010～0.020 mg/L和0.006～0.013 mg/L,湖水中的TP以溶解态磷(DTP)为主要存在形态,DTP主要以DP为主要形态存在;2和3号采样点TP浓度相对较高,表明该区域的磷形态受周围环境的影响较大.
