摘要
目的通过对月亮泡自然参数及氮磷等有机污染物指标进行检测,初步评价月亮泡水质目前的营养状况。方法依据相关的国家标准和环境规范对丰水期和枯水期的水样进行检测,并对丰水期和枯水期的结果进行统计学分析。结果pH值略高,呈碱性或弱碱性;除丰水期总氮外,其余指标均未超过我国《地表水环境质量标准》Ⅲ类水域水质标准。根据总氮评价月亮泡水质为富营养状态;总磷结果表明月亮泡水质为贫营养;高锰酸钾指数结果表明月亮泡为中营养状态。结论月亮泡处于中营养状态,生态系统健康状况总体上维持在较好水平。
Objective To evaluate eutrophication by general index and organic matter of Yueliang Lake in Jilin Province.Methods On the basis of related national standards and environment criteria,the index of Yueliang Lake in rainfall season and rainless season were determined,the data of rainfal1 season and rainless were compared.Results The pH value was a little higher than normal.All the parameters except TN in rainfall season were lower than the water quality standard of class Ⅲ Surface Water Quality Standards in China.According to TN,TP and CODMn,Yueliang Lake is separately eutrophic,oligotrophic and mesotrophic.Conclusions Yueliang Lake is in mesotrophic state.The water ecosystem state of Yueliang Lake is healthy and the water quality is good for the fish growth and production.
