中文摘要：

河在民族生活和然而，强烈人的活动打破了的农业生产起一个重要作用河生态系统的原来的生态的平衡，和影响结构和功能。恢复损坏的河生态系统回到健康地位，有效生态的恢复措施需要被实现。损坏的河面对的主要问题是水质量的水力的设备，或恶化的建设影响的局部地改变的水文学过程源于污染排出物，或两个。在这研究，设计控制或污染影响的河的生态的恢复技术分别地被考察。另外，三种方法，即物理、化学、生物生态的方法为走水路影响的河在细节被介绍污染。目前，河恢复技术的发展显示出下列趋势：1 ) 生态的恢复的规模正在变得更大；2 ) 生态的恢复措施被要求遇见多重目的；并且 3 ) 水环境的管理从水质量管理正在改变到水的生态系统管理。

英文摘要：

Rivers play an important role in people＇s living and agricultural production, however, intense human activities have broken the original ecological balance, and affected structures and functions of the river ecosystem. To restore the damaged river ecosystem back to a healthy status, effective ecological restoration measures need to be implemented. The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities, or the deterioration of water quality resulted from pollution emissions, or both. In this study, ecological restoration techniques of the rivers affected by engineering control or pollution are reviewed respec- tively. In addition, three kinds of methods, i.e. physical, chemical and biological-ecological methods are introduced in details for the rivers affected by water pollution. At present, the development of river restoration techniques shows the following trends： 1） the scale of ecological restoration is becoming larger; 2） ecological restoration measures are required to meet multiple objectives; and 3） the management of water environment is changing from water quality management to aquatic ecosystem management.
