摘要
在探讨潜在蒸散量计算方法的基础上 ,计算出孟津县农田潜在蒸散量和土壤含水量 ;并根据笔者实测的土壤含水量资料 ,得出土壤含水量桑斯威特算值的修订公式 ,进而求得孟津县土壤含水量、农田实际蒸散量、降水亏缺量 ,归纳出孟津县土壤水分循环特征和剖面动态特征。
The paper probes into the methods of calculating the potential evaporation and gives an appropriate method to calculate soil water content and potential evaporation. According to the data on soil water content collected by the author, the paper works out the revised formula for calculating water soil content by Thornthwaite Method, thus getting the correct value of water content in soil, actual moisture evaporation and shortage of rainfall. Based on the data, the paper concludes that the circulation of soil moisture in Mengjin County is roughly divided into two periods and four stages.
