| 摘 要： | 以黑龙江省齐齐哈尔市甘南县东兴村为试验点,对土壤有机质进行常规统计及半方差分析。结果表明,球形模型为最佳拟合模型,该区有机质具有中等程度的空间相关性,并探讨了其空间变异特征,为该地精准农业的研究提供了一定的理论参考。

| Abstract: | Dongxing village Gannan county Qiqihar city in Heilongjiang Province was selected as study area,conventional statistic and semi-variance of soil organic matter was analyzied.The results showed that the best fitted model was spherical model,the organic matter had the spatial correlation with moderate degree in the area,and the spatial variability characteristics of organic matter were discussed,which providies some reference for the study of precise agriculture in the area. |

| Keywords: | organic matter Geo-statistics semi-variance spatial variance |
