中国甘蔗气候类型和特点的客观分析

Analysis of Climatic Types and Characteristics for Sugarcane Planting in China

依据作物生态学原理选定评价指标,应用系统聚类法进行全国甘蔗气候分类。划分的9类甘蔗气候区都呈现明显的区域性分布,其气候特点既反映光、温、水时段分配匹配的差异,也反映气候要素总量差异,基于同一标准分析了各类甘蔗气候的利弊影响。提高了对于我国甘蔗气候的整体性客观认识,对甘蔗生产管理有重要指导意义。

According to the principles of crop ecology, some evaluation indexes were chosen to classify Chinese climates for sugarcane planting by hierarchical clustering method based on the climatic data of 76 weather stations from sugarcane-planting areas nationwide. The results indicated that nine sugarcane-climate types were classified, corresponding to the regional （ or zonal） distribution and reflecting the differences in temporal allocation of sunshine duration, temperature and rainfall and matching with plant growth. The positive and negative influences of climates on sugarcane planting were also analyzed under the same criterion. The results facilitated the understanding of Chinese sugarcane-planting climates and the management of sugarcane production.
