摘要: 介绍了无干旱时“期望产量”的确定方法,并据此可以求算出历年干旱对内蒙古粮食产量的损失量值,依据农作物不同生长期所发生的干旱的强度、范围以及作物对干旱的敏感度等关系,建立了干旱损失量的统计评估模式。并在2000~2003年赤峰市粮食产量评估中进行应用,效果较好。

关键词: 期望产量, 粮食产量, 干旱

Abstract: Based on the expected yield without drought,a loss estimation method of grain yield for drought was introduced.By analyzing the relationship between the yield reduction and several factors including arid intensity,influenced area,and crop sensitivity to drought,a constructure-based statistical model to estimate the yield reduction by drought was established.Using this model in ChiFeng region in 2000-2003,the result was very exact.

Key words: Expected yield, Grain yield, Drought
