Abstract: The paper points out that agriculture as the base of national economy is easily influenced by natural disasters.The close relationship between agricultural disasters and Chinese food production in the recent thirty years shows that natural disaster is a key issue of Chinese food safety and the agricultural disasters have a feature of cyclical fluctuation with some regional differences.Therefore,it is suggested that we should enact agricultural disaster relief and protect farmers' profits for solving "three agricultural problems" in China.The comprehensive solutions to agricultural disasters are as follows: adjusting the regional distribution of agriculture and livestock farming;developing projects and techniques for disaster relief;balancing the food price between harvest years and lean years;and establishing agricultural insurance.

Key words: agricultural disaster, cyclical fluctuation, comprehensive solutions

摘要： 本文认为,农业是国民经济的基础,也是最易受各种自然灾害影响的脆弱产业。近30年来,农业灾害与粮食产量的关联发展,揭示了农业灾害经济具有周期波动性和显著的区域分异规律,灾害是影响我国粮食安全的重大因素。为此,应当将减轻农业灾害和保障农业生产者的风险收益作为国家解决"三农"问题的重要方面,加强对农业灾害的综合治理,通过调整农牧业生产的区域布局、强化工程减灾措施与技术减灾措施、在丰歉年之间平准粮价、建立农业政策保险等,达到减轻农业灾害损失并维护农业生产者利益的目的。
