Abstract:

To understand the coastal resources and environment characteristics and take effective measures to prevent and control the coastal erosion disaster of Qingdao City, the authors synthetically reviewed the cause, the present character and the future development trend of coastal erosion disaster of Qingdao City. The authors found that due to some natural factors and human factors, such as global climate warming, typhoon and storm surge increase, sea level rise, sediment discharge decrease of rivers to sea, artificial sand mining, unreasonable coast project construction, the sand coast erosion was severe, the rock coast erosion of bay or harbor was slow relatively, and the sea level rise would aggravate the future coastal erosion of Qingdao City. Moreover, some relevant prevention countermeasures of coastal erosion were presented, such as strengthening the coastal zone exploration management, forbidding of digging sand in coast and beach, compensating sand to coast by human activity, constructing banks, groins and detached breakwaters, controlling headland, restoring and rehabilitating degraded salt marsh in coast and so on. The main shortage of the research was short of original data of coast erosion limited by fund and equipments, the authors suggested that the related units should strengthen the coast erosion process monitoring of Qingdao.
