摘　　要：以松花江一级支流蚂蚁河延寿水文站至莲花(二)站水文站60 km长的河段为研究区域,以国家Ⅱ级保护水生野生动物细鳞鱼为目标物种,绘制细鳞鱼产卵期水深、流速适宜性曲线,采用物理栖息地模型中的PHABSIM模型进行水力模拟,并绘制WUA-流量关系曲线。研究得出细鳞鱼4—5月产卵期所需最小生态流量为25 m^(3)·s^(-1),最适宜生态流量为60 m^(3)·s^(-1)。建议需要优化配置蚂蚁河灌区取水口的取用水量和取水时间,在保障细鳞鱼正常生存产卵的前提下发展农业经济。The 60 km long river section from Yanshou Hydrological Station to Lianhua Hydrological Station of Mayi River the level tributary of Songhua River is taken as the research area,stand by national levelⅡprotection aquatic wildlife Brachymystax lenok for target species,draw the water depth and flow velocity Habitat Suitability Curve of Brachymystax lenok,use the PHABSIM model of physical habitat model to hydraulic simulation,and draw WUA-flow curve.The results showed that the minimum ecological flow rate of Brachymystax lenok during spawning period from April to May was 25 m^(3)·s^(-1),and the most suitable ecological flow rate was 60 m^(3)·s^(-1).It is suggested to optimize the allocation of water intake and time of water intake in the Mayi River irrigation area,to develop agricultural economy under the premise of ensuring the normal survival and spawning of Brachymystax lenok.
