摘　　要： 本文根据大叶相思在广东不同引种区的标准地数据,用逐步回归方法筛选影响该树种生长的主要因子,再根据模糊聚类分析归纳为3个立地类型组及12个立地类型。其中,7个类型适于大叶相思生长;2个类型严重缺钾;2个类型要加强营造技术措施;1个类型不宜种植大叶相思。 In this paper the site factors influencing the growth of Acacia aurlculiformis were screened on the basis of the data collected at sample lots in different areas of Guangdong province by the method of step regression. These site factors were divided into three site type groups and each group subdivided into four site types by fuzzy classification and they evaluated. Results show that site types No. 1,2,5,6,7,9,10 were good for its planting. Types No. 3 and4 were seriously deficient in potassium. Types No. 8 and 11 needed more intensive planting. type No. 12 was not suitable for planting Acacia auriculiformis.
