Case Study on Ecological Restoration Technology for Eutrophication of Enclosed Campus Water Bodies
Water body is an important landscape element of the campus,and also a vital living resource for teach-ers and students in the park,which directly affects the daily life of teachers and students.Taking the campus envi-ronment transformation and greening project of University of Science and Technology of China(water ecological purification)as a case study,"external(internal)reduction,water oxygen,water purification and waterscape con-struction"is comprehensively considered as the governance idea.The water purification system of"aquatic forest"is constructed;The food chain of the ecosystem is improved and the"clean water-type and healthy water ecosys-tem"is restored.After the project implementation,submerged vegetation communities dominated by dwarf cold-resistant bitter grass were formed in the water system of USTC,which significantly restored the water ecology and improved the water environment.According to the tracking and monitoring analysis of the water ecosystem,the removal rates of TN,NH3-N and TP after the restoration of the water ecosystem reached 71%,83%and 71%re-spectively.Total phosphorus,ammonia nitrogen,etc.meet the surface water class Ⅳ standards.The construction of"aquatic forest"water purification system can improve water quality and biodiversity,and provide a reference for the ecological restoration of enclosed campus water bodies.
