摘要
通过对妫水湖水环境中的叶绿素a的测定并同时分析其水质,结果表明,妫水湖水域的叶绿素a的含量呈明显的时空变化特征,其中7月和10月含量高于6月、8月和9月,另外,1号、2号和3号位置的含量明显高于4号、5号和6号位置。叶绿素a含量与环境因子,如水中总氮、总磷、BOD5、CODMn有关。妫水湖叶绿素a含量变化多在(5～40)mg/m3范围内,说明妫水湖水体处于富营养状态。
According to the results of Chlorophyll-a and water quality which were monitored in same time in Guishui Lake of Beijing,it shows that the concentration of the Chlorophyll-a is varying noticeably with the time and the location,in which that it is higher in Jul.and Oct.than those in Jun.,Aug.and Sep.,while is higher in location No.1,No.2 and No.3 than those in location No.4,No.5 and No.6.It also shows that the concentration of the Chlorophyll-a is related with the environmental factors such as TN,TP,BOD5 and CODMn and ranged from 5 to 40 mg/m^3, which means that the Guishui Lake being in state of eutrophication.
