根据大辽河上游水库的来水量，通过对营口境内历年灌区各提水站的实际提水量比较，经过分析从而得出压盐流量与水库来水之间的关系。其结论为：大辽河槽内必须保持淡水7000～9000万 m3，才能保证压盐流量至田庄台，两岸才能正常引水。水稻泡插期严重缺水年份，大辽河盐分太高，水库加大放流压盐效果明显。
根據大遼河上遊水庫的來水量，通過對營口境內歷年灌區各提水站的實際提水量比較，經過分析從而得齣壓鹽流量與水庫來水之間的關繫。其結論為：大遼河槽內必鬚保持淡水7000～9000萬 m3，纔能保證壓鹽流量至田莊檯，兩岸纔能正常引水。水稻泡插期嚴重缺水年份，大遼河鹽分太高，水庫加大放流壓鹽效果明顯。

According to the reservoir inflow in the upper reaches of Daliaohe River,comparison the actual discharge of the irrigation area in each water pumping station for years in Yingkou,the relationship between the pressure salt flow and reservoir inflow is acquired.It is concluded that 70~90 million m3 fresh water must be kept in the river course of Daliaohe River in order to ensure the pressure salt flow to Tianzhuangtai,and the normal water taking can been guaranteed at two banks.There is a serious water shortage in the dry year for rice transplanting period,the salinity is too high.Reservoir increases the discharge to restrain the salinity.
