| Under the strategic background of China's comprehensive development of Marine economic power,port logistics industry as an important pillar of Marine economy,its development level is an important symbol of weighing a country's comprehensive competitiveness.Port logistics island plays an important role in the port logistics industry in China.The development of the port logistics industry in China depends on the safe,smooth and efficient operation of port logistics island.Considering the special geographical location and single ecological environment of the port logistics island,it reflects the ecological vulnerability and economic vulnerability when dealing with various disasters,presenting the characteristics of vulnerable ecosystem and difficult to recover,low self-adjustment ability,and affecting the long-term economic development.Therefore,how to minimize the loss of port logistics island in various disasters has become a serious and urgent practical problem.The purpose of this paper is to evaluate the disaster risk reduction capability of the port logistics island.The specific contents are as follows:(1)Taking the port logistics island as the research object,and evaluating the disaster prevention and reduction ability of the port logistics island as the research objective.By referring to the existing evaluation index system and research results of disaster prevention and reduction ability at home and abroad,combining with the characteristics of the island,the paper identifies the hazard sources of disasters based on the fishbone diagram analysis method,determines the eight principles for the construction of disaster prevention and reduction management system,establishes the evaluation index system for the comprehensive ability of disaster prevention and reduction of the port logistics island.(2)The disaster risk reduction management system of the port logistics island is endowed with subjective and objective combination.Firstly,the index is subjectively weighted with analytic hierarchy process,then the index is objectively weighted with entropy weighting method,and finally the index weight is combined with comprehensive weighting method.(3)Eight representative port logistics islands in Zhoushan city were selected for empirical analysis.Based on the evaluation of island disaster prevention and emergency preparedness capability,disaster emergency response and rescue capability and disaster recovery and reconstruction capability by hierarchical clustering method,the countermeasures and Suggestions for disaster prevention and reduction management of portlogistics island are put forward.Through the analysis of the research results,the following conclusions are obtained:(1)The disaster causes of port logistics island are mainly human factors,management factors,environmental factors and technical factors.(2)The abilities of pre-disaster prevention and emergency preparedness,in-disaster emergency response and rescue,and post-disaster recovery and reconstruction affect the disaster prevention and mitigation capability of the port logistics island.Disaster prevention and emergency preparedness are the most important.(3)Daishan island and Jintang island have better comprehensive ability of disaster prevention and reduction.Qushan island,Cezi island and Xiaoyangshan island have a general ability of disaster prevention and reduction.The comprehensive ability of disaster prevention and mitigation in Dayangshan island,Daxiaoyushan island and Dachangtushan island is poor.(4)From a single index,the indicators of the existence of such entities as the length of seawall,the number of Marine monitoring stations and the number of Bridges connected with the mainland are called disaster prevention and reduction hard power.The indicators that reflect the island's economic level,such as freight turnover,fiscal revenue and investment in infrastructure construction,will be called the soft power of disaster prevention and reduction.There is a coupling relationship between soft power and hard power. |
