本文对沈阳地区棕壤农田深度为２０ｃｍ的土壤含水量的空间变异规律进行了研究，结果表明该土壤的含水量测定值呈对数正态分布或正态分布，且其变异性较小，当置信水平为９５％、测量精度为平均值的５％时，样本容量Ｎ≥６；半方差分析结果表明，该农田土壤含水量的相关域约为１５ｍ。Ｋｒｉｇｉｎｇ插值法可以较好地表达土壤水分含量的空间变异情况。 In this paper, the spatial variability of soil moisture content of 20 cm deep brown farmland in Shenyang was studied. The results showed that the measured values ​​of soil water content were log-normal distribution or normal distribution with small variability. The confidence level was 95%, and the measurement accuracy was 5% of the average value, the sample size was N≥6. The results of the semi-variance analysis showed that the related field of soil moisture was about 15m. Kriging interpolation method can well express the spatial variation of soil moisture content.
