| 摘要: |
| 潜水蒸发是水均衡要素中主要消耗项之一。【目的】为探究不同土质裸地潜水蒸发与气象要素及埋深关系,【方法】本文利用淮北平原五道沟水文实验站潜水蒸发及气象实测资料,采用Mann-Kendall法检验不同土质裸地潜水蒸发年际变化趋势,利用spss统计法,分析了两种土质裸地潜水蒸发与6个气象要素的相关性,分别建立了多元回归模型,并利用Matlab软件构建了潜水蒸发系数与埋深的5种不同非线性拟合函数。【结果】结果表明：砂姜黑土潜水蒸发与气象要素相关程度从大到小依次为：地表温度、平均气温、降雨、日照,黄潮土潜水蒸发与气象要素相关程度从大到小依次为：地表温度、平均年气温、降雨、相对湿度、日照。不同土质潜水蒸发与气象要素的回归模型均达到精度要求(R2>0.7)。非线性拟合表明砂姜黑土在春夏两季威布尔函数模型拟合最佳(R2>0.98),而秋冬两季则是幂函数模型(R2>0.9)；黄潮土春夏两季威布尔函数拟合效果最佳(R2>0.96),秋季为幂函数模型(R2=0.963),冬季为指数函数模型(R2=0.962)。【结论】气象因素和埋深对潜水蒸发具有显著影响,可根据不同情况选择合适的潜水蒸发计算模型,用于潜水蒸发量计算。 |

| Abstract: |
| Diving evaporation is one of the main consumption items in the water balance element.【Objective】To explore the relationship between phreatic evaporation of different soil types and bare ground, meteorological elements and depth.【Method】This paper uses the water evaporation and meteorological data of Wudaogou Hydrological Experimental Station in Huaibei Plain.The Mann-Kendall method was used to examine the interannual variation trend of phreatic water evaporation in different soil types,and using the spss statistical method, the correlation between the two soil bare ground phreatic evaporation and six meteorological elements is analyzed, and its multiple regression models are established respectively, and the Matlab software is used Five different nonlinear fitting functions of phreatic evaporation coefficient and buried depth are constructed.【Result】The results show that the degree of correlation between phreatic evaporation of Shajiang black soil and meteorological elements in descending order is: surface temperature, average temperature, rainfall, sunshine, and the degree of correlation between phreatic water evaporation and meteorological elements in the yellow fluvo-aquic soil in descending order: surface temperature, average annual Temperature, rainfall, relative humidity, sunshine. The regression models of different soil phreatic water evaporation and meteorological elements all meet the accuracy requirements (R2>0.7). Non-linear fitting shows that the Weibull function model of Shajiang black soil is the best in spring and summer (R2>0.98), while the power function model is used in autumn and winter (R2>0.9); Huang Chao soil spring and summer Weibull function model The fitting effect is the best (R2>0.96), the power function model is used in autumn (R2=0.963), and the exponential function model is used in winter (R2=0.962).【Conclusion】Meteorological factors and burial depth have a significant impact on diving evaporation.The appropriate diving evaporation calculation model can be selected according to different situations, which can be used in this area Calculation of diving evaporation. |
