摘要
根据云南省干季（11月～翌年4月）的降雨量、气温、积温和日照时数等数据及空间分布与大麦生长适应性之间的关系，通过统计分析软件SPSS中的主成分分析和动态逐步聚类分析方法，结合GIS技术，对全省125个县市适宜大麦种植的区域进行气候类型的区划研究。结果表明：云南大麦气候生态类型可划分为中北部半干旱、中南部富热湿润、东部半湿润和西北部温暖湿润4个大麦种植区。
According to the relationship between data and spatial distribution of rainfall, temperature, accumulated temperature and sunshine hours in dry season （from November to April next year） and growth adaptability of barley in Yunnan province, the regionalization of climate types was conducted to 125 cities or counties in Yunnan province where suit to planting barley using principal component analysis method and dynamic stepwise cluster analysis method in statistical analysis software SPSS and GIS technology. The results indicated that climatic and ecological types for barley in Yunnan province can be divided into the north-central semi-arid area, the south-central hot and moist area, the eastern semi-moist area and the northwest balmy moist area.
