摘要
应用地统计学方法结合空间分析技术，对太湖流域典型土壤白土0～12．0cm、12．1～20．0cm、20．1～30．0cm的3层土壤样本和乌栅土0～15．0cm、15．1—28．0cm、28．1～42．0cm的3层土壤样本进行了数据处理和分析，并对土壤有机质含量的空间变异特征进行了探讨。结果表明：各层土壤有机质的空间相关性较弱，白土有机质含量的空间相关性低于乌栅土。
Geostatistics technology and geographic information system （GIS） were applied to analysis of the spatial variability of soil organic matte content in white soil （ 0 - 12.0 cm, 12. 1 -20. 0 cm ,20. 1 -30.0 cm）and Wushan soil （0 -15.0 cm,15. 1 -28. 0 cm,28.1 -42. 0 cm） ,which were typical soil of Taihu Lake region. The results showed that： soil organic matter content in different depths had weak correlation. The space relationship about soil organic matter content in white soil was lower than that of Wushan soil.
