| 中文摘要: |
| 在阐述洪水脉冲概念的基础上，指出洪水脉冲是河流-滩区系统诸如生产、分解和消费等基本生态过程的主要驱动力。随后分析了洪水脉冲生态学机理。并在讨论洪水脉冲概念中考虑了河流水文情势的重要性，研究了洪水脉冲对河流-洪泛滩区的生物过程的影响，讨论了洪水脉冲概念对河流生态修复的指导意义，提出了基于自然水文情势改进水库调度的原则，指出河流-洪泛滩区系统不可分割的整体性，恢复河流与滩区、湖泊和湿地的连通性是实现洪水脉冲的必要条件。 |
| 英文摘要: |
| The role of flood pulse which acting as the driven force of essential ecological processes such as production，decomposition and consumption in river_floodplain systems is expounded and the ecological mechanism of flood pulse is analyzed．The impact of hydrological regime on organisms and specific process of river_flood systems is studied．The significance of flood pulse concept on guiding the ecological restoration of river is discussed．The operation principles of reservoirs based on natural hydrological regime for improving the management of river are proposed accordingly,in which the integral characteristics of river_floodplain is emphasized．It is pointed out that the rehabilitation of connectivity among river channel，floodplain，lake and wetland is the essential approach for river ecological restoration． |
