Research on Eutrophication of Water in Typical Wetland Parks in Chengdu City
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 ur-ban 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 a-nalysis of the causes of eutrophication in urban wetland parks is conducted,and corresponding measures and sug-gestions such as source control,biological control,and phased implementation of comprehensive plans are pro-posed 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.
