北京市绿地中不同水体水质状况的监测与比较

摘要

水域景观是城市绿地,尤其是公园绿地中最为重要的组成部分,其水体水质状况的优劣经常成为社会、媒体关注城市生态环境的一个焦点.本文使用YSI6600EDS多参数水质检测仪,选择了北京城市绿地中水源不同、可能污染源不同的4个典型水体(公园湖泊、河道水域、再生水人工湖以及高尔夫球场水体)进行为期3个月的水质监测,分析比较了不同水体水质变化的原因.结果表明,以再生水为水源的水体电导率及盐度均高于其它水体,而高尔夫球场水体的溶解性总固体及蓝藻密度均高于其它水体,说明城市绿地中水体的水质不仅与供水水源有关,也与水体周边的绿地面源污染有关.%Water landscape is a kind urban green space,especially is one of most important part of urban park green space,the advantages and disadvantages of water quaíity conditions became a focus of social and media attentions in urban ecological environment.By choosing the four typical water areas (park lakes,fiver water,artifìcial lakes and golf course water) with different water sources,different possible pollution sources as the observation objects,the water quality monitoring to the four typical water areas were conducted for a period of 3 months by using YSI 6600EDS multi-parameter water quality detection instrument,and the causes of the water quality changes in different water areas were analyzed.The findings show that the conductivity and salinity of the water which took the recycled water as water source were higher than that in other water.This proved that the water quality in urban green space not only associated with water sources but also and did with the green ground source pollution around the water.
