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.
