Influencing Factors of Bare Soil Phreatic Evaporation Critical Depth Using Geographical Detector
摘要
Abstract
To further reveal the critical depth of phreatic evaporation and its influencing factors for different soil types in the Huaibei Plain,observational data from 62 sets of undisturbed soil lysimeters(0～5 m)collected at the Wudaogou Experimental Station during 2006-2024 were used in this study.Four nonlinear functions were constructed to determine the optimal fitting relationships between monthly phreatic evaporation and phreatic depth from January to December,and the critical depth of phreatic evaporation for each month was identified.The geographical detector method was then applied to analyze the dominant driving factors and their interactions affecting the critical depth of phreatic evaporation.The results showed that:① the annual critical depth of phreatic evaporation in Shajiang black soil ranged from 1.51 to 2.69 m,with an average value of 2.13 m,while that in Huangchao soil ranged from 2.95 to 4.15 m,with an average value of 3.74 m.The nonlinear fitting results showed good agreement with the observed data.② For both soil types,meteorological factors exerted a greater overall influence on the critical depth of phreatic evaporation in Shajiang black soil than in Huangchao soil.Surface temperature,air temperature,absolute humidity,and vapor pressure deficit exhibited strong explanatory power(q>0.3)and were identified as the core driving factors.③In the Shajiang black soil area,interactions among the driving factors showed a two-factor enhancement effect,with combinations involving wind speed being the key driving interactions.In contrast,nonlinear enhancement dominated in the Huangchao soil area,and interaction combinations involving relative humidity played a dominant role.关键词
