| 摘 要： | 以山西省洪洞县霍泉灌区多块试验田的多次实地观测资料为基础,分析了田间土壤含水率的变异强度及其影响因素监测误差与变异强度及采样数目的关系,得出监测误差随采样数目的增大而减小,随变异强度的增大而增大,并讨论了合理的采样数目的确定。

| Abstract: | On the base of the situ data, the spatial variability of soil-water content and its influece factors are analysed, the correlation between monitoring error and spatial variability, and the correlation between monitoring error and sampling number are discussed. The result shows that the error decreases with the rise of sampling number, and rises with the rise of spatial variability. The determination of necessary sampling number is also discussed. |

| Keywords: | soil-water content spatial variability monitoring error |
