| Abstract: | The annual and interannual variances of groundwater level and the relationships among the groundwater level and the initial soil moisture,the initial groundwater level,temperature,sunshine,reference crop evapotranspiration,evaporation,precipitation in the Jianghuai Valley were analyzed.The forecasting models of groundwater level were built with step regression method,the degrees of providing water were calculated with relative analyses method and the draining waterlogging model in cultivated soil layers was built. |

| Keywords: | Groundwater level Forecasting model of groundwater level Draining waterlogging model in cultivated soil layers Jianghuai Valley |
