摘要
依据安徽省五道沟水文试验站观测资料,比较了不同公式在浅埋区黄潮土与砂姜黑土的潜水蒸发计算中的表现。建议使用彭曼公式计算的蒸发能力代替实测水面蒸发以提高拟合效果。对于黄潮土建议采用阿维里扬诺夫公式、沈立昌双曲线公式、叶水庭指数公式和幂函数公式计算潜水蒸发。对于砂姜黑土建议采用阿维里扬诺夫公式、沈立昌双曲线公式、叶水庭指数公式和反logistic公式计算潜水蒸发,不推荐在淮北地区使用清华大学公式。列出了各公式的拟合参数。
Based on experimental data on phreatic evaporation from the bare soil at the Wudaogou hydrology test station in Anhui Province, the representations of different empirical formulas have been compared for calculations of groundwater evaporation of fluvo-aquic soil and lime concretion black soil with the shallow groundwater table. The evaporation capacity calculated by Penman-Monteith formula is suggested to replace the water surface, evaporation observed for an improved regression. It shows that A- Verianov formula, the hyperbola type formula, the exponential type formula and the power type formula are better fitting the phreatic evaporation of fluvo-aquic soil, while A-Verianov formula, the hyperbola type formula, the exponential type formula and the inverse-logistic formula are better fitting the phreatic evaporation of lime concretion black soil. The Tsinghua formula is not suitable for the calculation of the phreatic evaporation in the Huaibei plain. The coefficients of each empirical formula are also listed.
