摘要

[目的] 探讨季节性冻融期土壤水热盐动态变化及其机理，对干旱半干旱地区土壤盐渍化防护与治理提供一定的理论依据。[方法] 以科尔沁草甸地为研究对象，利用2013年11月至2014年5月科尔沁左翼后旗阿古拉生态水文试验站草甸地试验点的水热盐观测资料，通过SHAW模型进行仿真模拟分析。[结果] 模型对土壤热量和盐分的模拟结果较好，模拟期土壤水分模拟的标准偏差（root mean square error，RMSE）为0.02~0.07。受草甸地地下水位影响，模型对含水率的模拟结果偏差较大，但其标准偏差及平均偏差均处于允许范围内。[结论] 将SHAW模型作为相关研究仿真模拟的优选模型，可以弥补人工观测数据间断或缺失的不足，可以被借鉴定量模拟预测农田在自然条件下的垂向一维冻土-非冻土系统内的水热盐迁移状况。

Abstract

[Objective] To explore the dynamic changes of soil hydrothermal and salt in seasonal freezing and thawing period and its mechanism in order to provide some theoretical basis for soil salinization protection and administer in arid and semi arid areas.[Methods] Horqin meadowland was taken as a research area. Where the hydrothermal and salt observation data of meadow in the Aruga Eco-hydrological Experimental Station of Horqin left-wing post in November 2013-2014

were simulated and analyzed by SHAW model.[Results] The simulated results of soil heat and salt were better

and the root mean square error (RMSE) was 0.02~0.07. Due to the influence of meadow groundwater level

the model has a large deviation from the simulation results of water content

but its standard deviation and mean deviation are within allowable range.[Conclusion] The SHAW model can be used as the optimal model for the simulation of the study. It can compensate for the shortage of artificial observation data intermittent or missing

and can quantitatively predict the migration of hydrothermal salt in the vertical one-dimensional permafrost and free permafrost system under natural conditions.
