云南小麦种植气候生态类型区划

Eco-climate Types Regionalization in Yunnan Wheat Growing Areas

为给云南小麦种植合理布局提供客观、科学的理论依据,根据云南气象条件与小麦生长适应性的关系,采用主成分分析与GIS技术相结合的方法,在云南小麦种植区进行了生态气候类型区划研究。结果表明:云南小麦气候生态类型可划分为南部富热湿润麦区、中部半干旱麦区、中部半湿润麦区和中北部冷凉麦区。

In order to provide an objective and scientific theoretical basis for rational distribution of wheat growth in Yunan,according to the relationship of the Yunnan weather conditions and wheat growth and adaptability, a study on eco-climate types regionalization in Yunnan wheat growing areas was conducted using statistical analysis software SPSS principal component analysis and GIS technology. The results showed that Yunnan Province could be divided into the following four types.the southern rich hot and humid wheat growing area,central semi-arid wheat growing area, central semi-humid wheat growing area and north-central cold wheat growing area.
