| Abstract: | 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. |
