基于系统聚类的河南省甜樱桃栽培气候区划研究

Cli matic regionalization of sweet cherry cultivation in Henan province based on hierarchical cluster analysis

【目的】研究河南省甜樱桃栽培气候区划。【方法】以1962—2001年的气象观测数据为基础资料,选择影响甜樱桃生长发育的6个关键气象因子作为区划指标,采用系统聚类分析法对河南省甜樱桃适宜栽培区进行了区划。【结果】将74个代表县(市)划分为4个生态栽培区,并划分出适宜栽培区、次适宜栽培区。【结论】结合生产现状对各区域的特点及建议进行评述,为优化河南省不同地区甜樱桃栽培品种布局提供理论依据。

【Objective】 The aim of the study was to choose suitable region for sweet cherry cultivation in Henan province. 【Method】 Six key meteorological factors which were closely related to sweet cherry growth and development were selected as indexes for regional division based on the meteorological data from 1962 to 2001. Hierarchical cluster analysis was also involved in the regionalization. 【Result】 74 cities and counties were divided into four ecological regions, including the suitable and the sub-suitable cultivation regions. 【Conclusion】 The character and development suggestions of different regions were described individually, which provided theoretical basis for optimizing sweet cherry variety layout in different zones.
