china is one of the few countries that has has suffered serious losses caused by natural disasters every year.

小 摘要：我国是世界上自然灾害发生频繁、灾害损失较严重的国家之一，每年都因自然灾害而使国民经济和人民生活遭受巨大的负面影响。

The evaluation model in the paper considers both the synthetic role of various disasters and socioeconomic level of disaster-influenced area, uses natural disaster index to indicate disaster hazard magnitude and to regionalize systematiclly taking Southern Sichuan.

Because agriculture is the world resists the natural disaster ability generally acceptedly very bad of" the minority industry", the our country is one of the most serious nations in generally accepted natural disaster in world again, the perfect agriculture insurance system's steady development toward the guarantee agriculture economy have the biggest realistic meaning.

由于农业是世界公认的抵御自然灾害能力极差的&弱势产业&，我国又是世界公认的自然灾害最为严重的国家之一，完善农业保险体系对于保障农业经济的平稳发展有着极大的现实意义。

Statistics over the last decade show that over 80 per cent of all natural disasters are of meteorological or hydrological origin. In the 1950s, losses from all natural disasters, including those of hydrometeorological origin, earthquakes and volcanic eruptions, were estimated at US$ 4 billion per year and in the 1990s at US$ 40 billion.

过去10年的统计显示，超过80%的自然灾害是气象和水文灾害。20世纪50年代，包括水文气象灾害以及地震和火山喷发在内的所有自然灾害造成的损失估计为每年40亿美元，到了90年代则为400亿美元。

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。

The natural calamities have always been the important problems during the development of our human society.

自然灾害一直是人类社会存在和发展所面临的重要问题，科学认识各种自然灾害的发生机制和规律，是我们有效对其进行预防和治理的根本途径。

In the paper, the authors select 13 index, and use the method of fuzzy cluster analysis for regionalizing synthetical agricultural natural disaster in Jinsha River Basin of Yunnan Province.

选取13个指标，运用模糊聚类方法进行了云南金沙江流域综合农业自然灾害区划，将该流域划分为3个农业自然灾害区、10个农业自然灾害灾害亚区，揭示了该流域农业自然灾害的地域差异性，为因地制宜地制定农业自然灾害防治规划及减灾防灾措施提供了科学依据。
