基于大辽河上游水库来水与压盐流量关系的研究

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。

Study on Relationship between Pressure Salt Flow and Upper Reaches Inflow of Daliaohe River

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.
