| 中文摘要: |
| 本研究以包括新塘河、沿山河、南大河和后横港在内的四条杭州市生态示范河道为考察对象,通过对上述四条河道生态治理手段的总结以及效果的分析,综合评价了杭州市城市河道生态治理的实践工作以及所取得的成效。上述四条河道经过不同生态治理措施后,水质状况都得到了明显提升,沉水植物恢复在水质提升中起到的作用最为明显。氨氮是河道生态治理最有效降低的污染物,而总磷的消减还需要其他手段的配合。河道流速对生态治理的效果也会产生影响。总的来说,杭州市城市河道的生态治理工作取得了显著地成效,但河道生态系统和生物多样性的恢复还需要进一步加强。 |
| 英文摘要: |
| In this study, four rivers for ecological demonstration in Hangzhou city, including Xintang River, Yanshan River, Nanda river and Houheng river are surveyed. For evaluating the practice and achievement of ecological treatment on city rivers in Hangzhou, the methods and effects of ecological treatment have been summarized and analyzed. After different ecological treatments, the water quality of these rivers improve obviously. Submerged macrophyte recovering plays the most obviously role for water quality improving. Ammonia is reduced most efficiently by ecological treatments, but the reducing of phosphorus needs the help of other treatments. Flow rate could affect the effect of ecological treatments. In general, the ecological treatment on city rivers in Hangzhou has made remarkable progress, but the recovery of biological diversity and river ecosystem should be furtherSstrengthened. |
