摘　　要：以内蒙古锡林浩特胜利一号露天矿北排土场为研究对象,基于现场采样数据,通过描述性统计法和地统计法结合ArcGIS研究了复垦排土场表层土壤容重、孔隙度、含水量的空间分布特征。通过半方差函数分析可以看出,土壤孔隙度和含水量的C0/C0+C值分别为8.19%和3.31%,具有较强的空间自相关性,容重的C0/C0+C的值为39.45%,属于中等空间自相关性。这3项物理指标均显示出了明显的空间分布特征,并且其分布特征在一定程度上具有对应性,这种对应性与相关性分析的结果是一致的,研究结果对制定合理的改良措施、指导该地区植被恢复与生态重建具有重要的意义。The authors took north dump of Shengli No.1 opencast coal mine as research object, collected sample data, and studied spatial distribution of topsoil bulk density, porosity and water content in reclamation refuse dump by using descriptive statistical method and geostatistical analysis combing GIS method. According to analysis of semi variance function, the C 0 /C 0 ＋C values of soil porosity and water content were 8.19% and 3.31% respectively, which had strong spatial autocorrelation. The value of C 0 /C 0 ＋C of bulk density was 39.45%, which belonged to the middle spatial autocorrelation. The three physical indexes showed distinct spatial distribution pattern with a certain degree of correspondence. The correspondence was consistent with the results of the correlation analysis. Therefore, the results had vital practical significance to establish reasonable improvement measures for vegetation restoration and ecological reconstruction.
