辽宁中部地区河道水平衡测试分析

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。

Test and analysis of water balance of rivers in Middle Liaoning Province

Water balance of Liaohe River,Hunhe River and Taizihe River was studied by Liaoning Bureau of Hydrology and Water Resources Investigation in the irrigation periods since 2004.The variation of water supply,water use,water losses,and water quality was analyzed.The field data from Apr.28 to Jun.2 in 2004 showed that water incoming,water supply,water use,and water losses were almost in equilibrium.The water transfer from reservoirs in irrigation periods has great effects on river pollutant sluicing,water purification,salt control in river mouth area,and improvement of ecological environment.
