The research on the focus of agro-climatic resources can provide scientific reference for the adjustment of agricultural planting structure, the layout of agricultural industrialization and the rational utilization of agro-climatic resources. In order to study the matching status and change trend of various agroclimatic resources in Liaoning region, the evaluation method and gravity center model of agroclimatic resources were used. This paper analyzes the spatial-temporal evolution characteristics of the gravity center migration of agro-climatic resources in Liaoning Province from 1961 to 2020 by applying the gravity center model, and discusses the coupling relationship between integrated agro-climatic resources and light energy, heat and water resources based on the coupling situation model.The results are as follows:（1） The gravity center of agro-climatic resources in Liaoning province is relatively stable at the county scale. In the past 60 years, the gravity center of comprehensive agro-climatic resources, light energy resources and heat resources has always been located in Panjin, while the gravity center of water resources is located in Anshan. The absolute distance of the gravity center of each resource is between 1.50-17.97 km.（2） The gravity center of integrated agro-climatic resource is close to the gravity center of heat resources in space distance, and the absolute distance is 1.17-34.87 km. The absolute distance between The gravity center of integrated agro-climatic resource and the gravity center of water resources is 45.45-115.27 km.（3） The mean variable consistency index of gravity center of light resources, water resources and comprehensive agro-climatic resources is 0.80 and 0.72, respectively, with a high coupling degree. While the mean variable consistency index of gravity center of heat resources and comprehensive agro-climatic resources is -0.29, with a low coupling degree. According to the analysis of gravity center of resources, the light resource advantage area is in northwest Liaoning, the water resource advantage area is in eastern Liaoning. So suggested that the development direction of agricultural industry with light preference and low water requirement can be considered to the northwestern Liaoning. The agricultural industry with high water supply demand should focus on the southeastern Liaoning.
