摘要： 采用10℃积温数据对1980～2013年间攀枝花烟区热量条件进行分析,解析了攀枝花烟区10℃积温的空间格局及变化趋势,对比了不同区域及各区县间的差异,为研究区依据不同热量条件制定相应的烤烟种植与栽培制度提供数据支持。结果表明：研究区10℃积温呈南部东区、西区及仁和县高而北部盐边县和米易县低的空间格局,在1980～2013年间,研究区10℃积温总体呈上升趋势(5.44℃/a),在空间上呈西北部盐边县高而东部低的格局。分区县比较来看,东区、西区及仁和区地处金沙江河谷,10℃积温较高且变化趋势最明显,米易县和盐边县海拔高积温低且变化趋势较低,其中米易县10℃积温变化趋势最低,由于两者纬度一致,因此积温变化曲线也相对一致。

Abstract: To investigate the thermal condition of Panzhihua tobacco planting area from 1980 to 2013, the spatial pattern and change trend of the 10℃ AAT in Panzhihua tobacco planting area were analyzed, and the differences among regions and districts were compared, to provide data support for the formulation of the corresponding cultivation and cultivation system of flue-cured tobacco on the basis of heat conditions. The results showed that: the 10℃ AAT was higher in the east and west district of southern Panzhihua and Renhe County than that in Yanbian and Miyi County of northern Panzhihua, and presented an increasing trend (5.44℃/a) from 1980 to 2013. The east and west district and Renhe County are located in the valley of Jinsha River, which has higher 10℃ AAT and obvious change trend, Miyi and Yanbian have high altitude and low change trend, Miyi has the lowest change trend of 10℃ AAT, and the changing curve of these two counties is relatively uniform due to the same latitude.
