摘要
依据渭干河灌区潜水蒸发实验场观测资料 ,分析了潜水蒸发随埋深、土质及气象条件下的变化规律 ,对潜水蒸发量进行了公式拟合。结果表明 ,对于壤土类 ,幂函数型和清华公式拟合较好。对于砾石和细砂 ,阿氏公式和清华公式拟合较好。研究结果在生产应用中有一定的实用价值。
Based on the data observed by the groundwater balance station in Weigan river irrigated area of Xinjiang ,laws of the phreatic evaporation influenced by the soil texture,phreatic water depth and the atmosphere evaporation were analyzed and empirical formulas for estimating phreatic evaporation are regressed. It showed that Power Type Formula and Tsinghua Formula are better fitting the phreatic evaporation of loam soil, while А веръянов Formula and Tsinghua Formula are better fitting the phreatic evaporation of gravel and fine sand. The results have some useful values when applied in practice and production.
