摘要
本文根据黄淮地区及其周边地区1981～2000年农业气象资料，导出1个计算小麦拔节后遭遇霜冻温度风险度（F）的经验方程，以F为指标做出黄淮麦区小麦霜冻的农业气候区划。进而根据F和方程中的参数，评价各类防御措施在各分区的必要性、有效性和可行性。
Winter wheat becomes sensitive to frost injury once in elongation stage. Based on agricultural climatic data of HuangHuai Area and the environs,an assessment function was developed to assess the degree of risk（F）wheat encounters in frost temperature. The agricultural climatic division of frost was then plotted out,using F as an indicator. Based on F and the function parameters,application of frost preventive measures in the different divisions was discussed in terms of necessity,validity and feasibility.
