| 摘 要： | The paper builds up the forecasting model of air temperature according to the data(1994-1998)of Fu Jin area.At the same time,the writer inquires into the relation of water requirement of well irrigation rice(ET)and average air temperature(T).Furthermore,the rice irrigation water reuqirement(ET)of Fu Jin area has been forecast in 1999.Thus,we can apply the model in irrigation management.
