摘　　要：[目的]评价分析农作物气候生产潜势，充分掌握光、温、水气候资源储量和利用程度，为当地农村经济发展提供依据。[方法]用气候生产潜势数学模型揭示辽阳市农作物产量利用气候资源的程度。[结果]以粮豆产量为例，历年在利用气候资源方面，农作物气候生产潜势规律性不明显，但揭示了光、温、水条件匹配协调的年景是丰收年。[结论]辽阳市主要作物气候生产潜势较为强劲，变化幅度为10500～21300kg／hm^2，各作物之间变化趋近一致，充分利用气候资源提高作物产量还有一定的空间。[ Objective] To evaluate and analyze the crop climatic production potential, fully grasp the use of light, temperature, water resources, climate reserves to provide a basis for the local rural economic development. [ Method] With the mathematical model of potential climatic production, this study revealed the use of climatic resources in crop production in Liaoyang City. [ Result] Taking the yield of grain soybean as an example, the crop production potential law was not obvious in the use of resources over the years, but it revealed the coordination of the light, temperature, water conditions would be a fruitful year. [ Conclusion ] Liaoyang City, the main crop climatic production potential was robust with a change range of 10 500 - 21 300 kg/hm^2 ,the changes of the crops tend to be similar, so there is still space to make full use of climate resources to improve crop yields.
