【摘要】 河流修复是维护河流健康的重要措施,根据修复重点可分为近自然生态工法、水文模式修复法、河流分类法3类。河流修复具有时间和空间变异特征,包括系统条件和河流水文、结构、物质以及物种3个层面,修复的重点是创建多样性河流形态和改善河流水文条件,本文给出了河流形态多样性修复的主要内容和修复的概念性框架。考虑自然河流径流过程和河道生态保护目标,给出了河道不同保证率条件下的最小生态补水量、适宜生态补水量以及平滩补水量的计算方法,以为水库生态调度提供依据。更多还原

【Abstract】 River restoration is an important measure to maintain river health.Based on the emphases of river restoration,it could be classified into three types,namely ecological engineering method,hydrology pattern method and river classification method.According to the spatial and temporal,the main way of river restoration is to improve the river morphology and hydrology pattern.It pointed the content of river morphology restoration and built the conceptual model of river morphology restoration.It put forward the computing way of the minimal ecology filling water,feasible ecology filling water and bankfull filling water of different situation.更多还原
