农业气候资源重心研究可为农业种植结构调整、农业产业化布局及农业气候资源合理利用提供科学参考.为研究辽宁区域内各种农业气候资源匹配状况和变化趋势,利用农业气候资源评价方法和重心模型,分析了 1961-2020年辽宁省农业气候资源重心位置轨迹变化的时空演变特征,基于耦合态势模型,探讨了综合农业气候资源与光能、热量、水分资源相互之间的耦合关系.结果表明:(1)辽宁省农业气候资源重心在县域尺度上移动相对稳定,60年来综合农业气候资源重心、光能资源重心和热量资源重心始终位于盘锦市境内,水分资源重心位于鞍山市境内,各资源重心年代际间绝对移动距离在1.50～17.97 km.(2)综合农业气候资源重心与热量资源重心在空间距离上较接近,绝对距离在1.17～34.87 km;与水分资源重心距离最远,绝对距离在45.45～115.27 km.(3)光能资源重心、水分资源重心与综合农业气候资源重心的变动一致性指数均值分别为0.80、0.72,耦合度较高;热量资源重心与综合农业气候资源重心的变动一致性指数均值为-0.29,耦合度较低.综上所述,根据农业气候资源重心位置移动及各因子间耦合关系分析,辽宁西北部是光能资源优势区,辽宁东部是水分资源优势区,建议喜光且对水分要求较低的农业产业发展方向可考虑往辽宁西北部发展,对水分供应需求较高的农业产业应着重考虑辽宁东南部.
Spatial and Temporal Characteristics of Agricultural Climate Resource Center in Liaoning Province for Recent 60 Years
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 re-gion,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,re-spectively,with a high coupling degree.While the mean variable consistency index of gravity center of heat re-sources 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 advan-tage area is in eastern Liaoning.So suggested that the development direction of agricultural industry with light pref-erence 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.
