Abstract

Structures like flexible concrete mattress which influence the local substrata and the aquatic environment a lot are widely used in a type of common river regulation projects,the central bar protection． Based on the project of Daokouyao central bar protection,this study puts forward an ecological shoal consolidation method aiming at the channel central bar: through the introduction of out-soil and the tough pioneer vegetation including clover,reed as well as Bermuda grass． Before the vegetation breeds flourish enough,the straw -rope weavings are temporarily used as soil fixed meshes in case it is washed away． The results show that the engineering practice has a good ecological effect．The pioneer vegetation has thrived and other plant species have emerged a year after the implementation which both illustrate the method＇s suitability for generalization．

Key words

Central bar protection / vegetation / ecological shoal consolidation / scouring test
