云龙湖水质调查与评价

Water Quality Investigation and Evaluation for Yunlong Lake

对云龙湖水质进行了调查与评价。在云龙湖东湖、西湖区各设置3个采样点,监测水体中TN、TP、IMn、NH3-N、DO和SD指标;分别使用模糊识别法和湖泊综合营养指数对水体进行水质评价与富营养化评价,结果表明,云龙湖水质级别为Ⅲ类,其中TN、TP超标明显,水体呈现中度富营养化;不同功能区水质差异明显,东湖区水质优于西湖区,云龙湖功能区划分对水体有显著影响。

The water quality of Yunlong Lake had been investigated for environmental evaluation.TN,TP,IMn,DO,SD,NH3-N,and transparency were monitored in 3 sampling sites at eastern and western parts of the lake.The levels of water quality and eutrophication were computed by using fuzzy pattern recognition and TLI index.The results of evaluation showed that water quality of Yunlong Lake belonged to Ⅲ level of water quality,TN and TP were out of limits of state surface water standard,lake water was mesotrophication,different function areas had the water quality different significantly,water quality in eastern part lake was better than that of in western part,functional regionalization of the lake had obvious impact on water quality.
