It has the functions of intercepting sediment, purifying water, stabilizing reservoir bank, conserving water source and reducing sedimentation, and plays an important role in maintaining biological survival and reproduction space, enriching species diversity and maintaining ecological structure stability. The high-frequency scouring of waves and runoff rainwater on the water-level-fluctuation belt leads to serious soil loss and plant death. The ecological environment of the water-level-fluctuation belt is special and unstable, and is sensitive to external changes and interference, so it is easy to be destroyed. Therefore, as an important part of ecological civilization construction, the ecological restoration of the water-level-fluctuation belt is urgent. At present, most of the soil loss phenomenon of the water-level-fluctuation belt is reduced by engineering measures such as concrete slope protection, such as geocell slope protection, hinge type slope protection, interlocking type water conservancy block slope protection and spray mixed vegetation type slope protection. However, these slope protection methods cannot provide a good habitat and breeding space for aquatic species such as fish, shrimp and fungi. Fish nest brick can provide a good habitat for fish spawning and dolphin feeding, further improve the interaction between water and land, and become an effective way to protect the ecology of water-level-fluctuation belt. However, the fish nest bricks on the market have the problems of insufficient wave dissipation function, low structural strength and loose connection between fish nest bricks. SUMMARY
