一种海岸植被群落分区建植优化设计方法
By optimizing the design of coastal vegetation community zoning and planting, selecting suitable tree species and grass belt widths, and forming a planting pattern of "high in front and low in back", the problem of insufficient ecological environment isolation and disaster prevention capacity of traditional seawalls is solved, the survival rate of vegetation and wave dissipation efficiency are improved, and disaster resilience is enhanced.

AI Technical Summary
Traditional seawalls have a simple structure, which blocks the exchange of energy in the ecological environment and is easily damaged during extreme storm surges. The traditional single coastal vegetation layout restricts the ability to dissipate waves and reduce disasters, some tree species are difficult to survive, and the ecological disaster reduction capacity is insufficient in a limited space.
The coastal vegetation community zoning and planting optimization design method is adopted. Suitable tall and low tree species are selected, the zoning width is determined according to the width of the shoal and wave conditions, and the planting pattern of 'high in front and low in back' is formed by combining the calculation of the width of the grass belt. The wave energy attenuation theory is used to determine the high-efficiency wave dissipation zone and the width of the grass belt, and the dike design is optimized.
It increased vegetation survival rate by 30%, and the wave dissipation rate per unit width by up to 20%, enhancing disaster resilience, reducing the threat of storm surges to the city, and maximizing the improvement of ecological disaster reduction capabilities.
