【摘要】 抚仙湖窑泥沟湿地是云南高原湖泊第一块人工湿地,建于2001年,至今已整整运行10a了。为了保障工程的效能,对工程结构的完好性及其运转状态进行调查研究,结果表明,人工湿地对入湖污染负荷能进行有效去除,但由于管理维护跟不上,湿地出现老化、淤塞、过水能力减弱及净化效率降低,需对湿地进行清淤输通,修复湿地的正常运行效能。更多还原

【Abstract】 Yaonigou Wetland,the first man-made wetland of plateau lakes in Yunnan,has been in operation for 10 years since 2001.In order to keep the engineering works in effective operation,a study has been carried out about its structure and operational status.It shows that the wetland could effectively remove the inflowing pollution load.However,its performance is weakening in water passage and purification due to aging and blockage because of mismanagement and insufficient maintenance.Dredging is needed to rehabilitate the wetland.更多还原
