摘要
2010年、20111年和2012年7月对北京翠湖湿地水环境进行跟踪调查与监测,评估湿地恢复之后翠湖湿地水环境的改善效果。恢复区水体pH值、总氮(TN)、总磷(TP)、电导率(EC)和溶解氧(DO)等指标在3年间都表现为下降趋势。其中,pH值从2010年的8.36降到2012年的7.44;TN从2010年的1.94 mg/L降到2012年的1.76 mg/L;TP从2010年的0.129 mg/L降到2012年的0.117 mg/L。说明翠湖湿地经过湿地恢复后,总氮(TN)、总磷(TP)去除效果明显,湿地水环境良好改善,水体自净能力得到加强。本研究可为湿地水环境恢复评估及管理提供一定的科学依据。
Surveys and monitoring of water environment in Cuihu Lake wetland of Beijing were conducted in July of 2010,2011 and2012 to assess the effects of wetland restoration.The value of pH,total phosphorous,total nitrogen,electrical conduct and diluted oxygen in the area of restoration showed a decreasing trend over the 3 years.Among the indicators.pH value dropped from 8.36 to 7.44 from 2010 to 2012;TN dropped from 1.94 mg/L to 1.76 mg/L from 2010 to 2012;TP dropped from 0.129 mg/L to 0.11 7 mg/L from2010 to 2012.After the implementation of the wetland restoration project,the water environment in the restoration area was improved and the self-purification capacity of the water ecosystem was strengthened.This study would provide a basis for the assessment of wetland restoration and management of the water environment.
