| 摘 要： | 利用2002、2003年和2006年采集的土壤盐分剖面分析数据，探讨了黄河三角洲不同土壤盐分剖面类型及其时空分布特征。结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

| Abstract: | Types of soil salinity profiles and its temporal-spatial distribution characteristics in the Yellow River Delta were studied and discussed through analyzing data of soil salinity profiles collected in May 2002 and October 2003 and May 2006,respectively.Compared to May 2002 and October 2003,topsoil congregative type of soil salinity profiles increased in May 2006.The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006,and the topsoil congregative ty... |
