摘要
本文用多元统计分析研究江西省农业气候资源地域分异,结果表明,全省光、热、水资源的分布,受地形影响较大,地带性不甚明显,总资源的分布从东南向西北递减;影响江西省农业生产的主导因素是热量条件;全省可分为6个农业气候资源地域区、15种地域类型,山地农业气候资源型可以划分为3层。
This paper researches into the agroclimatological field in Jiangxi province by components analysis, cluster analysis and multifactor integrated evaluation. Three components provide 81.82% informations on the agroclimatological field. The first component shows the heat condition, the second the illumination condition, and the third the water content. Accordingly the agroclimatological resources in Jiangxi province can be divided into six areas and fifteen types. The mountain agroclimatological resources can be divided into three levels.
