该文以观音岩水电站为例,根据河道断面曲线和水位~流量关系计算出各水力参数计算,然后用湿周法, Tennant法和R2-CROSS法对观音岩水电最小生态流量进行了分析计算。研究表明对于大型河流用Tennant 法和R2-CROSS法计算的最小生态流量较接近且相对合理。
該文以觀音巖水電站為例,根據河道斷麵麯線和水位~流量關繫計算齣各水力參數計算,然後用濕週法, Tennant法和R2-CROSS法對觀音巖水電最小生態流量進行瞭分析計算。研究錶明對于大型河流用Tennant 法和R2-CROSS法計算的最小生態流量較接近且相對閤理。

In order to maintain the stability of river basin ecosystem , to ensure the security of river ecological water requirement , it is very important to select the appropriate ecological water requirement .Taking Guanyinyan Hydropower Station for an example , according to the relationship between river cross section curves and elevation and flow , hydraulic parameter has been calculated , and then the wetted perimeter method , Tennant method and R2-CROSS method have been used to calculate the minimum ecological flow of Guanyinyan hydropower .Through research , it is shown that for large river the minimum ecological flow which calculated by Tennant method and R2-CROSS method are close and relatively reasonable .
