| 摘 要： | 分析估算大汶河干流生态基流量是解决其生态环境恶化问题的基础。根据大汶口水文站历年径流资料,采用Tennant法、基流比例法等多种水文学法推求生态基流值,通过计算不同水平年的年际、年内不同水期和鱼类产卵育幼期生态基流量,在分析了各种方法应用区间和适用条件的基础上,综合考虑拦蓄引水工程和河道生态基流缺失等因素确定了大汶河干流生态基流。认为:基流量为1.1~14.1m~3·s~(-1)能更好地代表该区域不同水期的河道生态需水,经分析其生态基流保障程度基本达到90%以上,说明本文采取的方法在计算代表北方季节性、雨洪型河流的生态基流时是合理、可行性的,并进一步提出了生态基流的保障措施。

| Abstract: | Analysisof the ecological base fow is the basis to solve the problem of ecological environment deterioration in the Dawenhe RiverBasin. Acording to the annual runoffdata from the Dawenkou Station, the Tennant method and basic flow ratio method were used to calculate theecological base flow.And the amount of the ecological base flow in the Dawenhe River were determined by calculating the base flow for fishspawning breeding in the dferent level years, and taking the water structures and ecological base flow loss into consideration. The results showthat the base flow of 1.1~14.1m''/s is better for the ecological water demand with the ecological base flow security degree reaching more than 90%. |
