[Objective] The research aimed to study the changes in precipitation trends in Dongling District of Shenyang during 1951-2008 and provide basis for the adjustment of the local agricultural structure. [Method] Under the support of Excel program, using precipitation variability, linear regression and standard deviation coefficient and other methods, the trends in changes in precipitation were analyzed. [Result] During 58 years, the annual rainfall reduced 155 mm, the rainfall in crop growing season reduced 160 mm. And that in summer and autumn reduced by 95 and 50 mm respectively. After 1980, the probability of below-normal precipitation increased. The trend changes of precipitation days were consistent with precipitation. The precipitation days reduced 15 d and the effective precipitation days reduced 5 d. [Conclusion] The trend reduction of precipitation and precipitation days increased the probability of drought, which brought new issues for the current crop structure. It was imperative to adjust the layout of agriculture for the adaptation to climate change.
