摘要: 以楚雄州烤烟种植区为研究对象,利用SPSS(Statistical Program for Social Sciences)软件的主成分分析和动态逐步聚类方法,进行生态、气候类型的区划试验研究,区划结果在GIS平台上输出。该方法综合了气候、地理和土壤等多种生态因子,区划结果更客观定量,可被延伸引用。区划中排除了人为干扰因素,结果将楚雄州按生态类型划分为低海拔富热、富湿植烟区,中海拔温暖植烟区,高海拔温凉植烟区和中低海拔富热区4个烤烟可种植区和1个燥热非植烟区,区划结果与区内多年的种植实践相一致,对指导烟叶生产具有现实意义。

关键词: 农作物种植区, 生态类型区划, 主成分分析, 动态逐步聚类

Abstract: Taking tobacco-planting areas as research objects,the experimental study of ecological and classification of climate type were carried out by using the methods of principal component analysis and dynamic stepwise cluster analysis of Statistical Program for Social Sciences(SPSS).The results were output in GIS platform.The method integrated various ecological factors,such as climate,geography,and soil,so the divisional result was more objective and quantitative.The results could be extension cited.Eliminating factors of human disturbance,the result which was based on ecological type divided Chuxiong prefecture into five regions: low elevation excess heat,rich wet tobacco area,middle elevation warm tobacco area,high altitude warm cool tobacco area,low-medium rich hot area and non hot planting area.The divisional result was consistent to several years planting practice in the area,and had practical significance in guiding tobacco production.

Key words: Crop planting areas, Ecotype division, Principal component analysis, Dynamic stepwise cluster analysis
