摘　　要：土壤水分是影响植被建设的重要因素,对晋西黄土高原土壤水分的统计属性以及从不同深度水分的拟合性作了研究,结果表明水分呈正态分布,且随深度增加湿度增加,分布更集中,不同深度土壤水分具有很高的拟合性,且随时间变化其变异具有一致性的关系。Soil moisture is one of the most important facts that influence the recovery and construction projects of vegetation.In this paper,authors studied the statistics of soil moisture and analyzed the correlation at different depth.The results indicated that water content showed the normal distribution,the humidity increase with the depth deeper and the distribution is more concentration.It also indicated that there was a significant correlation between the soil moistures in different depth and they vary in the same way along the time.
