提本文根据安徽省12个农业气象观测站冬小麦春霜冻害观测调查数据，针对不同品种（春性和半冬性）冬小麦，全面分析了拔节期前15 d至拔节后20 d的最低气温变化规律，以日最低气温为指标，将春霜冻害等级划分为轻度和重度2个级别，并分时段确定等级。验证结果表明，虽然春霜冻害的发生受地形、土壤等多种因素的影响，但最低气温指标基本能够反映出冬小麦拔节前后不同品种春霜冻害的发生规律，可以在霜冻监测预警业务中应用。用该指标进行霜冻发生风险分析的结果表明，安徽省冬小麦主产区为轻度霜冻频发区、重度霜冻基本不发区，冬小麦春性品种春霜冻高发区比半冬性品种明显偏南，可用于指导冬小麦品种合理布局，减轻春霜冻危害风险。

Based on the data of 12 agro-meteorological observation stations in Anhui Province,the variation of daily minimum temperature from 15 days before jointing stage to 20 days after jointing stage was ana-lyzed,aiming at different varieties of winter wheat (springiness and semi-winter).Taking daily minimum temperature as index,spring frost damage to winter wheat is divided into two grades:light and severe. The verification results show that,although the spring frost damage is affected by many factors such as landform,soil etc.,the index based on daily minimum temperature can basically reflect the regulation of the spring frost damage to different varieties of winter wheat,and can be used in the monitoring and warn-ing services.Then,the risk of frost was analyzed using this index,and the results show that,in the wheat producing regions of Anhui,light spring frost occurs frequently while severe spring frost hardly takes place .The high-incidence areas of spring frost damage to springiness wheat is obviously further south than that of semi-winter wheat.This conclusion can be used to guide the rational distribution of winter wheat varieties,and reduce the risk of spring frost injury.
