During the researchperiod, the researcher collects a great number of literatures and research data. On theadvanced bases, the paper summary the achievement of previous development innatural disaster risk research both in domestic and abroad for references. Starting fromearth systemic and scientific thought, the paper makes analysis on the maincharacteristics of natural disaster risk system and probes into the theories and methodsof natural disaster risk assessment. The paper apply Remote Sensing and GIStechniques to take apart the dynamic assessment ways and modes of natural disasterrisk in diverse scales cities, in order to provide scientific basis for urban disaster riskdecreasing and risk decision-making management.

在国家自然科学基金项目&中国沿海城市自然灾害风险评估体系研究&和重点项目&沿海城市自然灾害风险应急预案情景分析&的资助下，调查分析了中国沿海典型城市自然灾害发育特征及其风险管理，获得了大量的文献资料与数据基础上，借鉴国内外自然灾害风险研究进展的成果，从地球系统科学思想出发，分析了典型城市自然灾害风险系统主要特征，探讨城市自然灾害风险评估方法与理论，并应用遥感和GIS技术，剖析城市不同尺度下的自然灾害风险动态评估途径和范式，为城市综合减灾降险和风险管理决策提供科学依据。
