九台市不同利用方式下土壤铬含量及其空间分布特征

Shuitu Baochi Xuebao, 2006
基于传统统计学和地统计学原理，分析了菜地、旱地和水田3种耕作方式对吉林省九台市土壤重金属铬分布的影响，并研究了整个区域铬含量的空间异质性特征。结果表明，菜地和水田土壤中铬含量明显高于背景值，存在积累现象，而旱地不明显。用球状模型来拟合整个区域铬含量的理论半变异函数效果最佳，铬分布具有较好的空间结构性，自相关范围较大，属于强空间相关。同时，各向异性分析表明该区域的铬含量分布是各向同性的。通过普通Kriging插值发现，铬含量的高值区主要分布于九台市东北部的岛状区域和西南部 ...

土壤盐分和含水量的空间变异性及其CoKriging估值——以黄河三角洲地区典型地块为例

Shuitu Baochi Xuebao, 2006
以黄河三角洲地区典型地块为研究区，运用经典统计学和地统计学相结合的方法研究了不同深度土层盐分和含水量的空间变异特征。结果表明：研究区土壤盐分和含水量普遍较高，土壤表层积盐作用明显；各层土壤盐分均属于中等变异强度，土壤含水量除表层为中等变异强度外，其余各层为弱变异强度；受结构性因素和随机性因素的共同作用，各土层盐分和含水量均具有中等的空间相关性。对Kriging插值结果分析表明，研究区各土层盐分和含水量在一定的范围内均存在着空间上的相关性和变异性，表层土壤盐分和含水量的空间分布主要受微地形和气候条件的影响，
