摘要
根据闽东北沿海滩涂土壤剖面化验数据，比较分析了该地区海涂土壤的理化性状及相关性，并分析了总盐量与８种主要离子的相关性，结果表明，有机质与全氮、全磷、阳离子代换量存在显著相关性，土壤总盐量与Ｃｌ－、ＳＯ２－４、ＨＣＯ－３、Ｃａ２＋、Ｍｇ２＋、Ｋ＋、Ｎａ＋存在显著的相关性。
Based on the laboratory test data of beach soil profiles in northeastern Fujian,the phys-ical and
chemical characteristics of the beach soils and the relativity were compared and analyzed. The
relativity between the total salt amount and eight main kinds of ions was also analyzed.The
results showed that there was an obvious relativity between the amount of organic substance
and that of total N,total P,and cation exchange capacity and between the amount of total salt
and that of cl-,SO2-4, HCO-3, Ca2+, Mg2+,K+,and Na+.
