| Abstract: | According to the principle of soil water balance and the optimization technique in operations research,with the data oi soil moisture from 1980 to 1992 and consideration of special natural conditions and real state of crop growth in Jiangsu province,effective rainfall and the amount of complemental water from lower layer of soil was estimated. The models of calculating amount of upland fied water budget were developed. |
