摘要: 通过对1985-2004年实测气象和粮食产量资料的分析,得出:影响天水市玉米、冬小麦两大粮食作物产量的主要农业气象灾害分别是春旱、初夏旱、伏期连阴雨和上年秋旱、当年春旱及倒春寒天气,在此基础上建立了基于农业气象灾害强度的天水市玉米、冬小麦的气候产量数学模型,可为气象灾情评估和定量分析农业气象灾害对粮食作物产量的影响提供依据。

Abstract: Based on the meteorological data and yields of the main grain crops in Tianshui,the relationship between the agro-meteorological disasters and the food grain crop yields was analyzed by using the mathematical models.The result showed that the main agro-meteorological disasters which influenced the grain yields of winter wheat and maize were the spring drought,early summer drought,steady rain in hot summer,drought in the last autumn,and unreasonable cold in early spring.The mathematical models for the climate yield of winter wheat and maize were built up based on the intensity of the agro-meteorological disasters.
