安徽苹果生态区划的模糊聚类分析

Fuzzy Cluster Analysis of Apple Ecological Distribution in Anhui Province

本文根据苹果对生态条件的要求，选择了影响苹果生长发育的四个重要气象因子，采用模糊聚类方法，对安徽省栽培苹果的生态气候条件进行研究，初步划出了安徽苹果经济栽培的南线．作者认为，宿县、泗县以北地区是乔化苹果栽培的次适宜区，阜阳、寿县和定远一线为矮化苹果栽培的南线．

According to the apple ecological requirements,the four main climate factors which affected apple growth and development were selected in this paper.By means of Fuzzy clustering the ecoclimatic conditions of apple production in Anhui Province were studied,and the south boundary of commercial planting was divided basically.It was suggested that the north area of the line between Suxian and Sixian County could be a sub-suitable growing district for apple grafted on vigorous rootstock,and the line of Fuyang City,Shouxian and Dingyuan County should be the south boundary of apple dwarf tree cultivation.
