<正>临江仙·痴春Fairy on the bank of a river An obsessing spring芳草青青斗艳,桃花朵朵争鲜,春风弥漫荡初寒。雾中鸿雁返,烟雨润幽兰。绿水游船轻泛,青山白塔虚悬,罗裙酥手掩婵娟。朦胧心欲醉,羞怯步阑珊。——海棠朵朵

通过对松花江一级支流梧桐河中下游河道栖息地模型模拟和实地鱼类调查,分析了修复工程丁坝的水动力变化对鱼类栖息地的改善作用。基于流量内增加法(IFIM),应用水生生物栖息地模型(River 2D),考虑鱼类栖息地的流速、水深、遮蔽回水面积比3项指标,定义栖息地为差、中、良3个等级,模拟从小到大4个不同流量条件下顺直河道和丁坝河道鱼类栖息地等级的分布及变化,并通过实地鱼类调查数据验证修复工程丁坝对鱼类栖息地质量的改善情况。结...
