| 摘 要： | 以海南省海口市三江农场为研究区域,采集并化验海水倒灌后土壤样品191份,利用地统计学方法和空间插值法对区域土壤盐分空间变异特征进行了研究。结果表明:14个土层中土壤盐分的均值最大的为0~5 cm土层,土壤盐分平均含量达到9.63 g/kg,最小的是20~40 cm土层,盐分平均含量仅为4.36 g/kg;24个土层中第一层(0~5 cm)土壤盐分含量属弱相关性,第四层(20~40 cm)土层属于剧烈空间自相关性;3各土层土壤盐分分布格局差异明显,含盐量1 g/kg的各土层均没有分布;含盐量1~3和3~5 g/kg两个级别随着土层深度的增加面积逐渐增大,9 g/kg的级别则面积逐渐减少。不同深度土壤层土壤盐分含量差异明显,空间变异特征各不相同,总体呈现土壤盐分表聚特征。
