河流生态修复是指在充分发挥生态系统自修复功能的基础上，采取工程和非工程措施，促使河流生态系统恢复到较为自然的状态，改善其生态完整性和可持续性的一种生态保护行动。本书在深入论述河流生态系统过程与功能的基础上，系统地阐述了河流生态修复的规划方法、技术措施和监测评估方法。

本书共5章，阐述了河流生态系统的过程与功能，深入分析了各类经济建设活动对河流生态系统的影响；阐述了河流调查与分析，涉及地貌过程、景观格局、水文过程、物理化学过程和环境压力—生物响应分析；重点阐述了河流生态修复规划，包括规划的时空尺度，河流生态状况分级系统，修复目标与任务，修复规划原则、规划内容和编制流程以及修复措施工具箱；详细介绍了各类河流生态修复技术，包括河道内栖息地修复与加强，岸坡防护技术、洄游鱼类保护、水库分层取水设施、环境水流评价方法、兼顾生态保护的水库调度方法、污染源治理以及河湖水系连通性恢复等，同时链接了若干国内外工程案例；介绍了河流生态监测与评估，提出了全指标河流健康评估体系和基于负反馈分析的河流生态修复适应性管理决策支持系统技术。

本书融入了作者多年的研究成果，借鉴和应用了国际上生态修复领域的最新理论和方法，既具理论系统性，又具技术实用性，可供水利、水电、生态、环境、城市景观、园林、地理和国土规划等领域的工程技术人员、科研人员和管理人员参考，也可作为高等院校相关专业的教学参考。

River restoration can be defined as an ecological conservation action in order to restore the river ecosystem back to natural conditions and improve ecological integrity and sustainability by taking structural and non-structural measures on the basis of giving full play to the role of ecosystem self-restoration.On the basis of giving an in-depth discussion on the process and function of river ecosystem，the author systematically expounds the planning method，technical m easures，monitoring and evaluation methods of river restoration.

This book consists of 5 chapters，the author firstly expounds the structure，function and process features of river ecosystem and analyzes the impact and disturbances of various economic activities on the river ecosystem.Based on that，the author discusses river investigation and analysis methods related to river geomorphology processes，landscape patterns and hydrological processes，physical and chemical processes and environmental pressure versus biotic impact.In this book，emphasis is placed on the river eco-restoration planning methods，including the spatial and temporal scales，the rating systems of river ecological conditions，targets and tasks of restoration，principles of planning formulation，technical procedures and the tool box.A detailed introduction is also given to various technologies of river restoration，including the restoration and reinforcement of habitats in river courses，slope protection，protection of migratory fishes，evaluation of environmental flows，reservoir operation considering ecological conservation，treatment of pollution sources and water connectivity.Many domestic and international project cases are attached to this book.Finally，the author introduces monitoring and evaluation technologies of river restoration，proposes full-indicator river health assessment system and methods of decision-making and supporting system of adaptive management strategies for river restoration on the basis of negative feedback analysis

This book incorporates the author’s research outcome accumulated during past years by building upon and applying international cutting-edge theories and methods.It is both of theoretical and systematical significance，and of technical and practical importance.It can be a good reference book for technical，research and managerial personnel engaged in water conservancy，hydropower ecology，environment，urban landscape，gardens，geography and territory planning.In addition，it can also be taken as a teaching reference for institutions of higher learning.
