“星座”聚类法在县级气候区划中的应用研究

A Study on the Application of Grey Constellation Cluster Analysis in the Regional Classification of Climate at County Level

以福建省沙县气象资料为研究对象,首先应用灰色理论对主要气象因子进行灰关联分析,在此基础上,运用"星座"聚类分析方法探讨县级气候区域划分问题。结果表明:运用"星座"聚类法对县级气候进行区划与实际自然环境相吻合,并把沙县气候划分为3个类型区,从而为指导林业生产提供科学依据。

Based on the climate data obtained from Shaxian county,Fujian province,the main meteorological elements of climate were studied by means of grey relational analysis,and the mutual relationships between each meteorological element were defined. Furthermore,the method of grey constellation cluster analysis was applied to the regional classification of climates at county level. The results indicted that it was validity to use the grey constellation cluster analysis in the regional classification of clamates at county level,and the climate of Shaxian County was divided scientifically into three districts. The results of the study provides a scientific foundation for the guidance of forestry production.
