摘　　要：[目的]研究模拟模型技术在冬麦北移中的应用。[方法]在搜集河北省北部9个代表县多年气象资料和布置多点田间试验的基础上,结合小麦的抗寒生理特性,建立其抗寒性模型。[结果]运行模型预测小麦越冬状况,对其结果进行验证,决策出河北省冬麦北移安全北界为北纬41°以南的坝下地区。[结论]为研究小麦生长发育的动态变化规律以及环境、栽培技术对其发育的影响提供了有效工具。[Objective] The aim was to study on simulation mode application in winter wheat north moving.[Method] Based on meteorological data of many years collected in north of Hebei province,and arrangement of multi-location field experiment,mode against cold was constructed considering cold-resistance characteristics of wheat.[Result] Wheat overwintering was forecasted with the help of working mode,results were verified,and the safe northern boundary for wheat overwintering in Hebei was determined in regions below dam in the south of 41°N.[Conclusion] This study provided reference for exploration of dynamic rules of wheat growth,and growth influence by environment and plant technique
