【Abstract】 In this paper, it is described that utilizing the advantage of grey system theory and taking the data of precipitation from 1941 to 1986(46 years)in Urumqi area, a set of grey mobile state model was developed and thefuture 21 years’ precipitation tendency was studied. It was verified by thedata of precipitation from 1981 to 1986 years in Urumqi area. An ideal re-sult has been obtained. And the scientific bases were offered for forecastinggrain output and working out agricultural plan.更多还原
