为计算维持大凌河中游河道生态平衡所需水量,运用大凌河中游段朝阳站以及大城子站1970-2013年实测流量资料,运用最小生态径流法和适宜生态径流法计算大凌河中游段最小和适宜生态需水量,并采用国外Tennant法对计算结果进行了评价,研究结果表明,采用平水期取75%、枯水期取80%,丰水期取45%的保证率下的适宜生态径流作为大凌河中游适宜生态需水,将使得大凌河中游段生态环境到达一个极佳状态,有利于河流自身的生态健康和河流周围生物栖息地的保护。研究成果对于大凌河中游段生态保护和生态治理提供重要参考价值。
為計算維持大凌河中遊河道生態平衡所需水量,運用大凌河中遊段朝暘站以及大城子站1970-2013年實測流量資料,運用最小生態徑流法和適宜生態徑流法計算大凌河中遊段最小和適宜生態需水量,併採用國外Tennant法對計算結果進行瞭評價,研究結果錶明,採用平水期取75%、枯水期取80%,豐水期取45%的保證率下的適宜生態徑流作為大凌河中遊適宜生態需水,將使得大凌河中遊段生態環境到達一箇極佳狀態,有利于河流自身的生態健康和河流週圍生物棲息地的保護。研究成果對于大凌河中遊段生態保護和生態治理提供重要參攷價值。

To calculate ecological water demand of the Daling river midstream that can maintain the ecological balance of the river water needed,the flow data during 1970-2013 of Chaoyang and Dachengzi hydrological station,and the minimum ecological flow method and suitable ecological runoff method were used to calculate the appropriate and minimum ecological water demand in the midstream segment ,the Tennant method was used to evaluate the results.The results show that the water level of the ecological suitability to take 75% of the dry season to take 80%,45% of the wet period taken under guaranteed rate Daling river midstream runoff as appropriate ecological water demand will make Daling river midstream segment reach an excellent state of ecological environment conducive to their ecological health of rivers and streams around the habitat protection. The results provide an important reference value for ecological protection and ecological in the Daling river management segment.
