To reveal the effects of ecological factors on geo-herbalism,by researching the correlation between yields or qualities of Curcuma wenyujin and ecological factors.
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.
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 degrees C) and average rainfall from August to October, annual average rainfall, altitude, available potassium content in soil.
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.
通过研究温郁金产量或品质与生态因子之间的相关性，揭示生态因子对道地药材的影响。
将所测数据分为气象因子、土壤条件、道地药材产量与品质三个部分，运用SPSS软件进行典型相关分析。
结果表明，存在两个典型相关模型分别解释气象因子与药材产量或品质、土壤条件与药材产量或品质之间的相关性，且两个典型相关均达到显著或极显著水平。分析表明，影响药材产量或品质的主要生态因子为5至6月平均气温、高温日数（35℃以上）、8至10月平均降雨量、年平均降雨量、海拔、土壤速效钾含量。
本研究初步明确了影响温郁金产量和品质的生态因子，为揭示温郁金道地性提供了一定依据。
