摘　　要：水体是校园重要的景观要素,也是园区师生至关重要的生活资源,直接影响着师生们的日常生活。以中国科大校园环境改造与绿化项目(水体生态净化)为案例进行了分析探讨,综合考虑以“外源(内源)消减、活水增氧、水质净化、水景营造”为治理思路,构建“水生森林”水质净化系统,完善生态系统食物链,重新恢复“清水型健康水生态系统”;结果表明:项目实施后,中科大校园内水系水下形成以矮生耐寒苦草为主的沉水植被群落,水生态明显恢复,水环境明显改善,同时依据水生态系统跟踪监测分析,水生态系统恢复后对TN、氨氮及TP的去除率分别达71%、83%及71%,TP、氨氮等均达到地表水Ⅳ类标准。通过构建“水生森林”水质净化系统可以改善水体水质,提高生物多样性,为封闭型校园水体水生态修复提供案例参考。Water body is an important landscape element of the campus,and also a vital living resource for teachers and students in the park,which directly affects the daily life of teachers and students.Taking the campus environment 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 construction"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 ecosystem"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,NH 3-N and TP after the restoration of the water ecosystem reached 71%,83%and 71%respectively.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.
