云南大麦种植气候生态类型区划与评价

Delineation and Evaluation of Climate-ecological Types of Barley Growing Areas in Yunnan

为给云南大麦种植提供更为客观、科学的理论依据,根据云南干季(11月至4月)降雨量、气温(积温)和日照时数的时间、空间分布与大麦生长适应性之间的关系,利用统计分析软件SPSS中的主成分分析和动态逐步聚类方法与GIS技术结合,对云南大麦种植区进行气候生态类型区划和评价。结果表明,云南大麦气候生态类型可划分为中北部半干旱大麦种植区、中南部富热湿润大麦种植麦区、东部半湿润大麦种植区和西北部温暖湿润大麦种植区,其中中北部半干旱大麦种植区是云南大麦最适宜和优先发展种植区。

To provide a base for the barley production in Yunnan,the barley production regions were classified based on the relationship between rainfall,temperature and sunshine hours of time during the dry season（November-April） of Yunnan,and the spatial distribution,growth and adaptability of barley,using the principal component analysis of statistical analysis software SPSS and dynamic gradually gather class methods and GIS technology.The barley growing areas in Yunnan were analyzed through climatic factors,climatic and ecological types of regional test results and output of GIS platform.The results were that barley production in Yunnan could be divided as central and northern semi-arid barley growing areas,central and southern hot and wet barley growing areas,the eastern semi-humid barley growing areas and the northwest warm and wet barley growing areas.The central and north semi-arid barley growing areas were best and were given priorty of barleg production development.
