摘　　要：为了满足绿色发展的需要,近年来在水运工程建设中常进行生境恢复措施减少对环境的不利影响。目前河道的生境恢复措施主要偏向于岸坡生态建设。根据涡河实际情况,针对“四大家鱼”、荆涂峡鲤、长吻鮠以及底栖生物,探究其水深、流速适宜性曲线,在此基础上建立生境恢复模型,并提出在河道建立浅滩-深槽交错分布的生境恢复措施。利用生境恢复模型,研究不同流量条件下浅滩-深槽生境恢复措施的工程效果。结果表明,浅滩-深槽生境措施实施以后能有效提高鱼类和底栖动物的生境适宜度,可以扩大其生境适宜区域。To meet the needs of green development,habitat restoration measures have often been taken in water transport engineering construction in recent years to reduce the adverse impact on the environment.Current river habitat restoration measures are mainly the shore slope ecological construction.According to the actual situation of the Wohe River,this paper aims at the“four major Chinese carps”,Jingtu Gorge carp,leiocassis longirostris and benthic organisms,explores the water depth and the flow velocity suitability curves.Based on the habitat restoration model,the paper puts forward in the river shoal-deep trench staggered distribution of habitat restoration measures,and uses the habitat restoration model to study the engineering effect of shallow-deep trough habitat restoration measures under different flow conditions.The results show that the shallow-deep trench habitat measures can improve the habitat suitability of fish and zoobenthos and expand the habitat suitability area.
