将浑河干流划分为4个区域进行生态需水量计算.根据浑河干流特点,将其生态需水分为河流基本生态需水、河流稀释自净需水、输沙需水和蒸发需水.根据浑河水文要素变化特征确定各类生态需水量的计算方法,并对各类生态需水进行类型整合.计算结果表明：北口前站全年的生态需水量为0.55×108 m3,抚顺站为9.59×108 m3,沈阳站为6.93×108 m3,邢家窝棚站为10.55×108 m3,并给出了逐月变化,以利于浑河干流水资源优化配置.结合浑河干流水文要素变化特征,对其生态需水量特征进行了分析,并提出相应建议.

Main stream of Hunhe River is divided into four regions in order to calculate the ecological water demand.According to the characteristics of main stream of Hunhe River,ecological water demands are classified into river basic ecological water demand,river diluted self-purification water demand,sediment water demand and evaporation water demand. According to the hydrological variation of Hunhe River,the calculation methods of various types of ecological water demand are chosen,and the types are integrated. The results show that:the ecological water demand of Beikouqian station is 0.55×108m3/a,that of Fushun station is 9.59×108 m3/a,that of Shenyang station is 6.93×108 m3/a,and that of Xingjiawopeng station is 10.55×108m3/a.The monthly change of water demand is given to optimize the allocation of water resources. Combined with the characteristics of main stream of Hunhe River in hydrological factors, ecological water demand features are analyzed and some suggestions are put forward.
