To study the ecological suitability regionalization of Eucommia ulmoides, for selecting artificial planting base and high-quality industrial raw material purchase area of the herb in Guizhou.
Based on the investigation of 14 Eucommia ulmoides producing areas, pinoresinol diglucoside content and ecological factors were obtained. Using spatial analysis method to carry on ecological suitability regionalization. Meanwhile, combining pinoresinol diglucoside content, the correlation of major active components and environmental factors were analyzed by statistical analysis.
The most suitability planting area of Eucommia ulmoides was the northwest of Guizhou. The distribution of Eucommia ulmoides was mainly affected by the type and pH value of soil, and monthly precipitation. The spatial structure of major active components in Eucommia ulmoides were randomly distributed in global space, but had only one aggregation point which had a high positive correlation in local space. The major active components of Eucommia ulmoides had no correlation with altitude, longitude or latitude.
Using the spatial analysis method and statistical analysis method, based on environmental factor and pinoresinol diglucoside content, the ecological suitability regionalization of Eucommia ulmoides can provide reference for the selection of suitable planting area, artificial planting base and directing production layout.
研究杜仲生态适宜性区划，为贵州杜仲人工种植基地选址及优质工业原料采购区选择提供依据。
在对14个杜仲产区进行调查的基础上，获取松脂醇二葡萄糖苷含量及生态因子。采用空间分析方法进行生态适宜性区划。同时，结合松脂醇二葡萄糖苷含量，通过统计分析对主要活性成分与环境因子的相关性进行分析。
杜仲最适宜种植区为贵州西北部。杜仲的分布主要受土壤类型、pH值和月降水量影响。杜仲主要活性成分的空间结构在全球空间呈随机分布，但在局部空间有一个聚集点且呈高度正相关。杜仲主要活性成分与海拔、经度或纬度无关。
运用空间分析方法和统计分析方法，基于环境因子和松脂醇二葡萄糖苷含量进行杜仲生态适宜性区划，可为适宜种植区的选择、人工种植基地建设及生产布局指导提供参考。
