Abstract: Climate division indexes were confirmed through the analysis of agricultural meteorological condition which influenced orange-growing, agricultural climate division for orange-growing in Daying was conducted based on GIS technology. The appropriate area, medium appropriate area and inappropriate area for orange-growing in Daying were defined and described. The results showed that Tianbao, Jinyuan, Huima and the east of Penglai, Longsheng and Zhuotongjing along the Qijiang River were the appropriate area, which had abundant natural resources such as light, heat and water, and it was warm in winter.
