| 摘 要： | 运用地统计和GIS技术研究了土壤粒级的空间变异规律,绘制了空间分布图,进一步分析了土壤粒级和主要土壤养分之间的关系。结果表明,土壤粉粒(0.002~0.02 mm)的半方差函数符合指数模型,表现为中等强度的空间相关性,粘粒(<0.002 mm)和砂粒(0.02~2 mm)的半方差函数符合球状模型,表现出强烈的空间相关性,空间相关距离分别达到435,609和657 m。Kringing插值图直观地描述了不同粒径颗粒的空间分布特征,三者均呈现较明显的渐变性分布规律。除碱解氮外,土壤有机质、全氮、速效磷、速效钾均与粘粒含量呈极显著正相关(P<0.01),与砂粒含量呈极显著负相关(P<0.01)。土壤粒级可以作为土壤管理分区划分的一项重要依据。

| Abstract: | Spatial variability of soil particle composition was measured by use of geostatistics and GIS techniques for an 87 ha tobacco field with 100 m sampling interval in Chahe,Jia County,Henan Province.The spatial distribution of soil particle and its relationship with soil nutrients were analyzed.The results showed that the semivariogram for soil silt(0.02-0.002 mm) was well fitted by exponential model with medium spatial correlation,while soil clay(<0.002 mm) and sand(0.02-2 mm) by spherical models with medium ... |
