摘　　要：为研究城市湿地公园水生态健康情况,依据有关评价技术规范,结合成都生态环境特点,选取成都市浣花溪湿地公园、白鹭湾湿地公园以及麓湖湿地公园这3个具有代表性的城市湿地生态系统。分别在春、夏两季开展了水生态监测,运用湖泊综合营养状态指数对湿地水体富营养化程度进行了全面而深入的量化分析。结果显示,在夏季时期,3个公园湿地均为中营养状态:在冬季时期,浣花溪湿地公园的富营养程度相对其他2个湿地公园较高,且呈轻度富营养化,需加强湿地的水环境综合治理和生态系统修复。最后对城市湿地公园富营养化原因进行了分析,并提出了源头控制、生物控制、制定综合方案分阶段实施等相应措施和建议,为成都地区生态环境监测与综合评判、水资源长期有效管理及湿地公园内河流湖泊规划开发的技术支撑与策略制定提供科学依据,从而助力科学决策与可持续发展实践。To study the water ecological health of urban wetland parks,based on relevant evaluation technical specifications and combined with the characteristics of Chengdu's ecological environment,three representative urban wetland ecosystems,namely Huanhuaxi Wetland Park,Bailuwan Wetland Park,and Luhu Wetland Park,were selected.Water ecological monitoring was carried out in spring and summer,and a comprehensive and in-depth quantitative analysis of the eutrophication degree of wetland water bodies was conducted using the comprehensive nutrient status index of lakes.The results showed that during the summer season,all three wetland parks were in a moderate nutrient state,while during the winter season,the eutrophication level of Huanhuaxi Wetland Park was relatively high compared to the other two wetland parks,and showed mild eutrophication.It is necessary to strengthen the comprehensive management of wetland water environment and ecosystem restoration.Finally,an analysis of the causes of eutrophication in urban wetland parks is conducted,and corresponding measures and suggestions such as source control,biological control,and phased implementation of comprehensive plans are proposed to provide scientific basis for ecological environment monitoring and comprehensive evaluation,long-term effective management of water resources,and planning and development of rivers and lakes in wetland parks in Chengdu.This will assist in scientific decision-making and sustainable development practices.
