Description
技术领域technical field
本发明涉及冻土冻融监测及蒸发量计算，尤其涉及一种能够监测冻融过程的装置，和计算冻融过程各阶段冻土蒸发量的方法。The invention relates to frozen soil freezing and thawing monitoring and evaporation calculation, in particular to a device capable of monitoring the freezing and thawing process, and a method for calculating the frozen soil evaporation in each stage of the freezing and thawing process.
背景技术Background technique
土壤蒸发量数据是水文循环中的重要影响因子，在干旱半干旱地区的农业用水效率、生态能量平衡以及土壤盐渍化研究等多方面扮演着重要角色，因此是水文及土壤监测中最基本的观测要素。Soil evaporation data is an important factor in the hydrological cycle, and plays an important role in agricultural water use efficiency, ecological energy balance, and soil salinization research in arid and semi-arid regions. observation element.
目前寒区冻土蒸发的测量装置较少，主要由于季节性冻土整个冻融过程中土壤水分、热量以及溶质运移过程十分复杂。已有调查显示在非冻土区域相关土壤蒸发量有较为详细的研究，一些研究也将相似的数值模型方法用于冻土区域的土壤蒸发量评估，例如SHAW、CoupModel和HYDRUS等模型。这些模型将冻土区域的蒸发过程设定为与非冻土区域类似，从而模拟得出冻土区域水分、热量及溶质运移过程，从而再基于能量平衡和彭曼方程等经验性方法计算出蒸发量。然而，由于冬季冻土表面几乎不存在液态水，径流和水分运移也几乎停滞，这些方法不能准确刻画冻土冻融过程不同阶段的土壤蒸发量。因此，准备测定季节性冻土冻融过程不同阶段的蒸发量不仅可以揭示以上问题，也能为数值模型在季节性冻土区域更准确的进行模拟提供测试和验证数据。At present, there are few measurement devices for permafrost evaporation in cold regions, mainly due to the complex transport process of soil moisture, heat and solute during the entire freezing and thawing process of seasonal frozen soil. Existing surveys have shown that there are relatively detailed studies on soil evaporation in non-frozen soil regions, and some studies have also applied similar numerical model methods to soil evaporation assessment in frozen soil regions, such as SHAW, CoupModel, and HYDRUS models. These models set the evaporation process in the frozen soil area to be similar to the non-frozen soil area, so as to simulate the water, heat and solute transport processes in the frozen soil area, and then calculate based on empirical methods such as energy balance and Penman equation. Evaporation. However, since there is almost no liquid water on the surface of permafrost in winter, and runoff and water transport are almost stagnant, these methods cannot accurately characterize soil evaporation at different stages of the freezing and thawing process of permafrost. Therefore, preparing to measure the evaporation of seasonal frozen soil at different stages of the freezing-thawing process can not only reveal the above problems, but also provide test and validation data for numerical models to simulate more accurately in seasonally frozen soil regions.

完全冻结为冻融管内所有层温度探头的读数都低于冰点；Complete freezing means that the readings of the temperature probes of all layers in the freeze-thaw tube are lower than the freezing point;
开始融化为冻融管内最上层温度探头的读数高于冰点，其余层的温度探头读数低于冰点；Begin to thaw as the reading of the temperature probe of the uppermost layer in the freeze-thaw tube is higher than the freezing point, and the readings of the temperature probes of the remaining layers are lower than the freezing point;
完全融化为冻融管内所有层温度探头的读数都高于冰点。A complete thaw means that the temperature probe readings of all layers in the freeze-thaw tube are above freezing.
