从2004年起辽宁省水文水资源勘测局对辽河、浑河、太子河开展以灌溉期为主的水平衡测试研究,分析供水、用水、损失、水质变化规律。当年4月28日至6月2日的实测资料表明,各河来水量、供水量、用水量、损失水量等基本平衡,灌溉期水库调水对河道冲污、净化水质、入海口地区压盐和改善生态环境都起到重要作用。 Since 2004, Liaoning Province Hydrology and Water Resources Survey Bureau has carried out water balance test on the Liaohe River, Hunhe River and Taizi River, and analyzed the changes of water supply, water use, loss and water quality. The measured data from April 28 to June 2 of that year showed that the water balance, water supply, water consumption and loss of water balance of the rivers, water pollution of the reservoirs during the irrigation period, water purification, salt pressure in the estuary area And improve the ecological environment have played an important role.
