基于GIS的大英县甜橙种植农业气候区划研究

Agricultural Climate Division for Orange-growing Based on GIS in Daying

通过分析影响甜橙生长发育的农业气象条件,确定气候区划指标,基于GIS技术,完成大英县甜橙种植农业气候区划。得到甜橙在大英种植的适宜、次适宜及不适宜区,并进行分区评述。研究结果表明:甜橙在大英的适宜区主要位于郪江沿岸的天保、金元、回马及蓬莱镇、隆盛和卓筒井镇的东部,这些地区光、热、水资源丰富,冬季温暖,是县内最适宜种植甜橙的地方。该研究可为大英甜橙产业布局和持续发展提供科学依据。

Climate division indexes were confirmed through the analysis of agricultural meteorologicalcondition which influenced orange-growing, agricultural climate division for orange-growing in Daying wasconducted based on GIS technology. The appropriate area, medium appropriate area and inappropriate area fororange-growing in Daying were defined and described. The results showed that Tianbao, Jinyuan, Huima andthe east of Penglai, Longsheng and Zhuotongjing along the Qijiang River were the appropriate area, which hadabundant natural resources such as light, heat and water, and it was warm in winter. This study could providescientific basis for the industrial distribution and sustainable development of Daying orange-growing.
