中文摘要：
为了消减盐碱障碍和提升地力，研究了苏北典型滩涂新垦农田土壤盐分的空间变异性。结果表明，农田土壤盐分东低西高，整体上属轻度盐渍化（含盐量1．27～1．98g／kg），但存在着盐斑（含盐量大于2g／kg）。表层及次表层土壤含盐量空间自相关程度强烈，其结构方差比分别为88．88％、80．75％；而其余土层含盐量间自相关程度为中等。垂直方向上，土壤盐分主要集中在犁底层（20~40cm）。
英文摘要：
The spatial variability of saline-alkaline was studied to reduce soil salt content and inprove land fertility in the reclaimed mudflat farmland. The results showed that field was mild salinization with some por- phyritic severe salinization in the southwest. The spatial heterogeneity degrees of 0~20 crn and 20~40 cm in soil depth were strong dependent with the structural variation ratio [C/（C＋Co）] of 88.88%, 80.75% respec- tively however, only moderate degree of spatial heterogeneity was found in the other three soil layers. The top of soil salt content appeared in the 20~40 cm soil layer, which was the plow pan of the study field.
