河道生态需水量的确定对于河流生态系统健康至关重要，为计算大洋河河道内生态需水量，基于大洋河岫岩和沙里寨两个水文站1970-2012年流量资料，分别运用最小生态径流法以及本文提出的保证率为90%(枯水期)、75%（平水期）、60%（丰水期）的适宜生态径流法计算了大洋河河道内生态需水量，并运用Tennant法对计算结果进行评价分析并结合实测流量资料对大洋河生态径流满足度进行了分析，研究结果表明：适宜生态径流量可以使得大洋河河道内的生态环境状况在丰水期和枯水期达到极好的状态，而最小生态径流量也能使大洋河生态环境状况得到改善和稳定，大洋河在丰水期生态径流破坏程度要高于枯水期，本文的研究成果对于大洋河河道生态保护和治理可提供参考价值。

The river water to determine the ecological health of the river ecosystem is crucial for calculating Dayang river instream ecological water demand ,based on Dayang River and Shalizai river hydrological stations 1970-2012 annual flow of information ,namely the use of minimum ecological Runoff law and to ensure the proposed 90%(dry season),75%(flat water period),60%(wet period) the appropriate method to calculate Dayang river ecological runoff in the river ecological water demand and use of Tennant method of calculation analyze and evaluate the results combined with the measured flow data on Dayang river ecology runoff satis-faction were analyzed,the results showed that:suitable ecological runoff can make ecological and environmen-tal conditions within the river channel in Dayang River wet and dry seasons to achieve excellent condition ,The minimum ecological runoff Dayang river ecological environment can also improve and stabilize the river ,the o-cean river runoff in the extent of ecological damage wet period than the dry season ,results of this study Dayang river channel for ecological protection and governance can provide a reference.
