摘　　要：在红云集团3省9市(州)原料基地县(区)采集1 326个土样,运用因子分析法和系统聚类法对植烟区土壤养分状况进行了分析,结果表明:(1)红云集团原料基地县(区)植烟地土壤肥力总体处于中上水平;(3)烟区省际间土壤肥力综合排序为:云南>福建>贵州;(3)23个县(区)土壤肥力被聚合为5个档次:腾冲县单独为一类,土壤肥力最高;巍山、嵩明等7县(区)为第2类,肥力较高;建宁、安宁等5县为第3类,肥力水平中偏上;息烽、翠云等6县(区)为第4类,肥力中等;江口、沿河等4县为第5类,肥力水平中偏下。By factor analysis and systemic clustering analysis, cultivated soil fertility of material-base counties in hongyun tobacco group was studied in this paper. The results showed that, firstly, as a whole, soil fertility of material-base counties in hongyun tobacco group were in upper level. Secondly, the se- quence of soil fertility among 3 provinces was as follows： Yunnan was the utmost, Fujian was the middle, Guizhou was the bottommost. Thirdly, 23 counties＇ soil fertilities were classified into 5 types, Tengchong＇ fertility was the highest and classified into individual type 1. There were 7 counties fertility belonging to type 2, represented by Weishan and Songming whose soil fertilities were upper. Type 3 was composed of 5 counties, represented by Jiannin and Annin, whose soil fertilities were middle to Upper. Type 4 was com- posed of 6 counties, represented by Xifeng and Cuiyun, whose soil fertilities were middle. Type 5 was composed of 4 counties, represented by Jiangkou and Yanhe, whose soil fertilities were middle to lower.
