利用内蒙古赤峰地区10个监测站2005-2014年的气象资料和春播期土壤墒情监测数据，分析了春播期土壤墒情与气象条件的关系。结果表明，赤峰地区10个监测站春播前降水量、日照时数、气温、风速与秋季对应气象要素值变化趋势一致，具有明显的差异性，而蒸发量之间无明显变化。从区域分布来看，南部地区土壤墒情好于北部地区。春播前和秋季降水量与土壤相对湿度相关系数分别为0.411和0.358，均达到极显著正相关（P<0.01），蒸发量与土壤相对湿度相关系数分别为-0.216*和-0.269*，均达到显著负相关（P<0.05），说明降水量对土壤墒情的提高具有明显的促进效应，蒸发量对土壤墒情的增加具有明显的抑制作用。

The relationship between soil moisture during spring sowing and meteorological conditions were comprehensively researched with the observed data related to soil moisture content and meteorological conditions during ten continual growing seasons from 2005 to 2014 in Chifeng.The results showed that the precipitation, sunshine, temperature, wind speed before spring sowing period and in autumn have the same dynamic changes, but evaporation has different dynamic changes.The regional distribution of soil moisture in south of Chifeng is better than in north of Chifeng.For five meteorological factors, precipitation very significantly positive correlated with relative soil moisture,and the simple correlation coefficients were 0.411,0.358,respectly before spring sowing period and in autumn,evaporation significantly negative correlated with relative soil moisture,and the simple correlation coefficients were-0.216,-0.269,which implied precipitation and evaporation were the most important factors in determining soil moisture in spring sowing period.
