To counter the severe problem of coastal erosion in China,we study the main contents and commonly use methods of beach protection and siltation promotion.Based on the analysis of the advantages and disadvantages of both engineering measures and ecological measures and combining with actual cases,we summarize the existing application modes of beach protection and siltation promotion.According to the comparison of multiple aspects,we find that ecological measures can make up for the deficiencies of traditional engineering measures and make full use of the ecological environment to form a flexible barrier for the bank protection and revetment.This feature meets the needs for the construction of ecological civilization in China,thus the ecological measure has a good application prospect in beach protection and siltation promotion projects.
