A Study on Risk Assessment and Zoning of Sea Ice Disaster in Shandong Province

摘要

Sea ice disaster is one of the main marine disasters in Shandong province. To carry out risk assessment and zoning of sea ice disaster is helpful to guide the coastal governments at all levels to formulate and optimize the decision-making of sea ice disaster prevention and mitigation. Through selecting the sea ice thickness, density, period and all kinds of disaster bearing body density and scale as the evaluation index, the coastal county administrative region under the jurisdiction of Shandong Province as the basic evaluation unit area, a comprehensive assessment of sea ice disaster risk in Shandong province is carry out by using the weight analysis method etc. in this paper. On this basis, the risk of sea ice disaster in Shandong province is classified in spatial regions combined with the actual needs of the disaster prevention and mitigation of sea ice. And the risk grade distribution map is also drawn. The result reveals the distribution of sea ice disaster risk in Shandong Province more truly. It may provide a basis for the risk management of sea ice disaster in Shandong province.
