摘　　要：本文对内蒙古阴山北部农牧交错带耕作土壤进行了未冻水含量试验,得出了在不同初始含水量情况下的土壤未冻水含量变化曲线。并应用典型预报模型Anderson模型对该区粉壤土未冻水含量进行了预报模拟,并将模拟结果与试验结果进行对比分析,验证了Anderson模型对该区粉壤土未冻水含量模拟的可信度。通过阴山北部耕作土壤粉壤土的未冻水含量试验模拟研究,揭示了该地区粉壤土的冻结特性,明确了冻结粉壤土未动水含量随温度的变化规律,对进一步研究该地区的土壤冻融水热运移、土壤冻融作用下的结构变异、冻结粉壤土的含水量测试提供帮助。This article obtained a change curve on unfrozen water content in the different initial water content situation by experiments on unfrozen water content of cultivated soil in Farming-Pastoral zone of the North of Mountain Yin.It did a forecast simulator on unfrozen water content of cultivation silt loam by Anderson Model,a typical forecast model.It made a comparison between simulation results and the experimental results.The reliability of Anderson model on simulating unfrozen water content of cultivation silt loam in the region was verified.Through experimental studies on unfrozen water content of Cultivation silt loam in Farming-Pastoral zone of the North of Mountain Yin,it revealed freezing characteristics of cultivation silt loam in the region,and defined the change regulation about unfrozen water content of frozen silt loam along with the change of temperature.Above all,the experimental studies offers help to further studies on the region＇s soil freezing and thawing water and heat transport,the structural variation on soil freezing and thawing condition,and the water content of frozen silt loam soil test.
