Quantitative modeling of evaporation resistance in salt crusts under varying influencing factors
摘要
Abstract
Salt crusts are a typical surface structure in arid regions and significantly affect soil-atmosphere water transfer processes.The evaporation resistance of salt crusts is a key controlling parameter in the soil water-vapor evaporation process.However,quantitative understanding of salt crust evaporation resistance under varying influ-encing factors remains limited.Therefore,this study employs simulation experiments and theoretical analyses to dynamically monitor and analyze salt crust formation and the evolution of evaporation resistance under the in-fluences of soil particle size(fine sand:0.10-0.25 mm;coarse sand:0.50-0.85 mm),radiation(200 W·m-2,500 W·m-2,and 800 W·m-2),salt concentration(5.0%and 17.5%NaCl),wind speed(3.5 m·s-1 and 8.0 m·s-1),hydraulic conditions(with and without fixed groundwater),and evolution time.Using the Shapley additive expla-nation method,we quantified the contributions of the various factors and ranked their relative importance.The re-sults were as follows:(1)Salt crust evaporation resistance increased continuously over time.At the end of the ex-periment,the maximum evaporation resistance(9.39×104 s·m-1)occurred under the DL3 treatment(5.0%NaCl,no fixed groundwater,800 W·m-2 radiation,fine sand),whereas the minimum resistance(293.08 s·m-1)was ob-served under the WH2 treatment(5.0%NaCl,fixed groundwater,8.0 m·s-1 wind speed,fine sand).(2)The contri-bution ranking of the influencing factors was:hydraulic condition>radiation>evolution time>soil particle size>salt concentration>wind speed.Among these factors,radiation exerted a significant positive effect,whereas soil particle size had a negative impact on salt crust evaporation resistance.These findings provide theoretical support for the quantitative characterization of salt crust evaporation resistance.关键词
