摘要
叙述了河流环境流量的基本概念,并介绍了国内外四类计算方法:水文学法、水力学法、生境模拟法和整体分析法。通过水文学法、水力学法和考虑河流中鱼类的生态流速-流量法,对北部湾经济区河流环境流量进行计算。最后,对计算所得三种结果进行对比分析,确定生态流速-流量法计算结果25.75m3/s,作为北部湾经济区河流———南流江的最小环境流量。
This paper describeds the basic concept of environmental flow and introduces four kinds of domestic and foreign methods. They are hydraulic method, hydrological method, habitat simulation method and holistic analysis method. By means of hydraulic method, hydrological method and ecological flow velocity and flow method in which fish is taken into account, this paper calculates environmental flow of Beibu Gulf economic region. Finally, it compares and analyzes three results. The result of ecological flow velocity and flow method is minimum environmental flow of Nanliu River of Beibu Gulf economic region that is 25.75 m^3/s.
