A spur dike generally refers to a river regulation building extending into a river orthogonally or obliquely to a river bank, i.e., the end of the spur dike is connected to a bank in a "T" shape. The spur dike can change the water flow direction (the regulating effect of the spur dike on the water flow is shown in fig. 2 and 3), and scouring and accumulation phenomena are generated in the area near the spur dike (shallow and shallow pool terrains are formed between biological spur dikes, as shown in fig. 4).

The spur dike supports water flow, reduces water potential, and prevents rapid flow from approaching a river bank, thereby protecting and protecting the bank and preventing or reducing the scouring of the water flow to the bank; and under the synergistic action of water flow and silt, a microtopography of the riverbed, and a shoal-deep pool structure for artificially recovering and rebuilding the riverbed can be formed. Further, since the arrangement direction of the spur dikes is different, the positions where the erosion and the accumulation occur are different, and the river form can be diversified. The river course micro ecosystem improves the water quality by means of the water purifying capacity of the aquatic plants while increasing the diversity of habitat.
