A review of river management history in various countries is used in this thesis to discuss the future development trends of river management and the relationship between river health and river management.Based on the characterization and assessment of river health, Five components of stream condition are presented in this thesis to characterize river health: water quality, aquatic life, physical form, hydrology and streamside zone. It is obtained by comparing the methods and criteria that have been developed by others and reviewing the river assessment practices in various countries. Accounting for the features of urbanization region in plain river network, an indicator system for river health assessment which provides scores for 5 subindices and 17 indicators is established. With almost 200 stream reaches in Shanghai as objective of study and Liwa stream and Zhangjiabang Creek as case study, the application of river health assessment in the planning, baseline survey and post-project appraisal of river management is explored by collecting historical literature and field monitoring. Consequently, some suggestions to improve river management effectiveness are presented from the angle of river health.

本文回顾河流管理漫长历程并指出当前国际发展趋势，进而辨析河流健康状况与河流管理的关系；以河流健康状况的表征和评价为核心，通过对国外RIVPACS、AUSRIVAS、IBI、RCE、ISC等河流健康状况评价方法的分析和比较，以及对美国、英国、澳大利亚、南非等国家河流健康状况评价实践的总结，尝试从理化参数、生物指标、形态结构、水文特征、河岸带状况5个方面全面表征河流健康状况；结合中国东部平原河网地区自身特点，通过评价原则、评价指标、评价标准、评价权重确定等步骤，初步构建了包含河流水文、河流形态、河岸带状况、河流水质以及河流生物5个一级指标(共17个指标)的河流健康状况评价指标体系；在此基础上，采用资料收集与现场实测相结合的方法，以上海近200条中心河道为研究对象，以丽娃河和张家浜为典型案例，分别就河流健康状况在河流管理规划、现状评估以及后评估中的应用进行实证研究，并尝试探讨如何从这三个阶段利用河流健康状况评估改进河流管理的对策。
