中文摘要：
根据转移概率地质统计软件（T-PROGS）的基本原理，利用已知土壤剖面含盐量，建立研究区土壤盐渍化状况的三维结构模型，并对研究区域土壤盐渍化状况进行TSIM模拟。结果表明，轻度盐渍化和中度盐渍化各向同性比分别占研究地块体积的34．0％和54．1％，是研究地块的主要盐渍化类型，且在垂直和水平方向上分布具有较强的连贯性；无盐渍化、重度盐渍化和盐土分布相对离散。TSIM模拟对连续性较好的轻度盐渍化和中度盐渍化类型的模拟精度更高。
英文摘要：
According to the basic principle of the geological transition probability statistics software（T-PROGS）, soil salinization three-dimensional structure model in research area was established using theknown soil salt content in profile, and soil salinization was simulated by TSIM. The results indicated that：the mild salinization type and the moderate salinization type were the main salinization types in the studyarea, and their isotropic distribution ratios accounted for 34.0% and 54.1%, which represented that thedistributions in vertical and horizontal directions were strong consistent. Distributions of no salinization,severe salinization and solonchak were relatively discrete. There were higher precision for mild salinizationand moderate salinization types according to TSIM simulation.
