北京地区高尔夫球场人工湖富营养化分析研究

Studies on eutrophication of artificial lake in golf course in Beijingarea

为了评价北京地区不同季节高尔夫球场人工湖富营养化的现状,分析其产生的内在原因,对北京3家高尔夫球场2011年4~10月人工湖水体的理化性质进行了监测。结果表明：水体富营养化呈现明显的季节变化,并且 A 球场水体的整体状况显著优于B和 C球场。3家球场水体 pH 均呈现偏碱性,透明度较低；高锰酸盐指数均符合《地表水环境质量标准》中对Ⅴ类水的要求；叶绿素 a 的含量均高于富营养化状态的标准值。B和C球场总氮和总磷含量在个别月超过了Ⅴ类水的标准。除水温外,水体各参数间均具有显著的相关性。综合营养状态指数评价表明,3家高尔夫球场人工湖水体均已呈现不同程度的富营养化。

In order to evaluate the situation of eutrophication and analyze the underlying causes of artificial lakes of golf courses in different seasons in Beijing area,the physic-chemical properties of lake water were moni-tored in three golf courses （A,B and C）from April to October.The results showed that an obvious seasonal variation in eutrophication was presented and the overall condition of Course A was significantly better than that of Course B and C.In all three golf courses,the pH value of lake water was alkaline,the transparency value was low and the permanganate index was less than the Fifth Level of Surface Water Environmental Quality Stand-ard.Besides,the content of chlorophyll-a was higher than the eutrophication standard value.The contents of to-tal nitrogen and total phosphorus exceeded the Standard Fifth Level during several months in Course B and C. The tested water parameters were significantly correlated with each other except for water temperature.The comprehensive evaluation of trophic state index indicated that the eutrophication was in progress in three golf course artificial lakes.
