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。
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 regi...
