摘　　要：目的:研究生态环境因子与温郁金药材产量及品质的相关性,揭示环境因素对道地性形成的作用效应。方法:在SPSS中运用典型相关分析药材产量及品质组分别与气候组、土壤条件组的相关关系。结果:温郁金药材产量及品质与气候因素、土壤条件间相关性均有两对典型变量模型反映,典型相关达到显著或极显著水平,对药材产量及品质起主要影响效应的生态环境因子有:5～6月平均温度、8～10月高温(高于35℃)天数与降雨量、年均降雨量、海拔、土壤速效钾含量。结论:研究初步筛选出影响温郁金药材道地性形成的生态环境因子,为揭示温郁金道地性提供了基础。Objective：To reveal the effects of ecological factors on geo-herbalism,by researching the correlation between yields or qualities of Curcuma wenyujin and ecological factors.Methods：All measured dates were divided into three components,meteorological factors,soil conditions,the yields and qualities of geo-herbals,and analyzed through canonical correlation using SPSS software.Results：The results showed that there were two canonical correlation models to explain correlation between meteorological factors and yields or qualities of medicinal materials,as well as soil conditions and yields or qualities,and both of canonical correlations reached the significant or extremely significant level.The analysis indicated that main ecological factors affecting the yields or qualities of medicinal materials were average temperature from May to June,the days of high temperature（over 35℃）and average rainfall from August to October,annual average rainfall,altitude,available potassium content in soil.Conclusions：This study has tentatively made clear which ecological factors to affect the yields and qualities of Curcuma wenyujin;and provided some basis for revealing geo-herbalism of Curcuma wenyujin.
