沿海城市自然灾害风险研究

Research of the Natural Disaster Risk on Coastal Cities

自然灾害是当代国际社会、学术界普遍关注的热点问题。随着自然灾害突发强度、频度和广度的不断增长,自然灾害预防工作显得格外重要。沿海城市作为人口集聚、国民经济、社会发展重要区域和战略中心,自然灾害带来的损失是剧烈、致命的,亟待开展沿海城市自然灾害风险研究。该领域目前主要探讨的问题:自然灾害类型与风险辨识;脆弱性评价指标体系与评价模型;自然灾害风险评估与风险管理;自然灾害数据管理范式研究等。沿海城市作为自然灾害频发和受损严重的地区,在全球变暖和快速城市化背景下,目前应集中开展自然灾害风险实证研究:沿海城市脆弱性评价指标体系和综合脆弱性评价方法;自然灾害风险评估程序规范和动态评估模型;自然灾害数据管理范式与模板;自然灾害风险评估GIS工具集等。

Natural disaster is the hotspot question in international society and academe. Natural disaster prevention is very important since the constant increase in intensity, frequency and extent of natural disasters. A coastal city is an important area and strategic focus of people convergency, national economy and society development, so the loss of the cities from natural disasters is very fierce and fatal. At present, the main questions discussed in this field are： types and risk identification of natural disasters, the indexes system and model of vulnerability assessment, natural disaster risk assessment and management, and the pattern of natural disaster data management. As the natural disaster risk assessment and risk management of coastal cities started relatively late in China, in the background of global warming and quick urbanization, our research in the coastal coastal cities should focus on these aspects： the indexes system and method of coastal city vulnerability assessment, the assessment procedure criterion and dynamic assessment model of coastal city natural disaster risk, the pattern and template of coastal city natural disaster data management, and the GIS tools of coastal city natural disaster risk assessment.
