城市景观水体水质改善的生态修复工程实践--以上海市清涧公园中心湖为例

Practice of Ecosystem Restoration Project on Water Quality Improvement of Urban Landscape Water-Taking Central Lake of Shanghai Qingjian Park as an Example

随着经济和人口的迅猛发展,城市景观水体污染问题日益突出。同时,人们生活水平和精神需求不断提高,对城市环境和水体景观的要求也越来越高,这就对城市景观水体的生态修复提出新要求。以上海清涧公园中心湖水体生态修复为例,通过分析其污染成因、污染状况和湖水水质,开展生态修复技术分析,并确定工程设计和实施要点。研究结果表明,修复工程运行半年后,水质效果和生态景观均得到明显改善,氮磷等关键指标已达到地表水III类水质标准。该研究结果对城市景观水体的水质改善、生态修复和实施具有一定的借鉴意义。

With the rapid development of economy and population,urban landscape water pollution problem is increasingly outstanding.Meanwhile,the continuous improvement of people's living standard and spiritual needs has asked for the much better urban environment and water landscape,resulting a new standard to urban landscape water body ecological restoration.Taking the central lake ecological restoration of Qingjian park in Shanghai as an example,the ecological restoration technology has been analyzed in terms of the main reason and status of the contamination,and the key points of engineering design and implementation are determined.The results showed that the water quality and ecological landscape were significantly improved by the restoration of six months,and the key indicators such as nitrogen and phosphorus had reached the tertiary standard of surface water quality.The results of this study were significant for the improvement of water quality,ecological restoration and implementation of urban landscape water in the future.
