广西荔枝果树商业性栽培区的气候生态适宜度灰色聚类评估

根据荔枝生产气候生态条件，用二重灰色聚类方法分析广西荔 果树商业性栽培的气候生态适宜度，评估结果与当地荔枝生产实践相一致，由靖西，凌云，巴马，罗城等地到中，东部的融水，鹿寨 ，昭平，贺州一线的以北地域，均属无荔枝栽培基本气候条件区域；其以南地域，具备有荔枝栽培的基本气候生态环境，属广西荔枝栽培基本气候适宜区，在以南地域中，由二重聚类结果，得出柳城，象州，来宾，宜州，百色，田东，田阳，东兴，北海等地域为荔枝商业性栽培的次适宜气候生态区，其他地域为广西荔枝商业性栽培的最适宜气候生态区。

Grey Cluster Evaluation on the Climatic Suitability of the Commercial Growth Area of Litchi in Guangxi

The double grey cluster method is adopted to evaluate the climatic suitability of commercial growth areas of litchi in Guangxi. The evaluation results are in line with the local production practice. The Guangxi region is divided into three areas according to the climatic suitability of litchi growth by the double grey cluster method .The unsuitable area for litchi commercial growth is in the north of the line from Jinxi Lingyun Bama Luocheng to Rongshui Luzhai Zhaoping Hezhou.In the south area of the above line, the suitable area for litchi commercial growth is Liucheng, Xiangzhou,Laibin,Yizhou,Baise,Tiandong,Tianyang,Dongxing,Beihai;the other area is more suitable for litchi commercial growth.
