| 摘 要： | 为了对鱼类栖息地水力学环境进行准确、全面的描述,回顾了鱼类栖息地水力学问题的研究历史.根据特征量描述对象的不同,将用来描述栖息地特征的水力学变量划分为水流特征量、河道特征量、无量纲量和复杂流态特征量.在总结前人研究成果的基础上进一步对各特征量获得方法、使用范围进行评述.

| Abstract: | The study on the hydraulic problems about fish habitats was reviewed.According to different objectives,the hydraulic variables to describe the characteristics of fish habitats were divided into flow variables,channel variables, dimensionless variables,and complex flow variables.Based on the former achievements,the methods for obtaining each characteristic variable and the ranges of their application were summarized. |

| Keywords: | fish habitat ecohydraulics protection of fish resources spatial flow feature |
