| 摘 要： | 用灰色系统理论的方法对影响我国粮食生产易损性的因素进行了灰色关联分析，认为最主要的３个因素是：灌溉面积、国家粮食定购价格和粮田复种指数；而农户的生产性固定资产投资、化肥投入的影响相对较小。并指出了提高我国粮食生产抗灾能力的主要途径。

| Abstract: | This paper applies the theory of grey system to analyze the elasticity of vulnerability of grain yield in China.Grey relational analysis showed that irrigated area,price of grain and multiple crop index are very important for reducing the vulnerability of grain yield.Farmers'investment on fixed asserts,consumption of chemical fertilizers are relatively unimportant.The paper also points out that the main ways to reduce the vulnerability of grain yield rest with irrigated area expansion,appropriate grain pricing,and advancement of multiple crop index. |
