基于GIS技术的五味子品质区划研究

Quality of Schisandrae Chinensis Fructus regionalization based on GIS technology

为明确五味子优质药材产区空间分布,通过走访和实地调查,收集五味子药材样品和分布信息,基于五味子中4种木脂素类化学成分含量、生态环境因子和空间分布数据,利用GIS技术、最大信息熵模型、SPSS统计分析方法,进行五味子品质区划。结果显示五味子主要分布于辽宁的东北部、吉林的东部、黑龙江的东部。五味子醇甲含量较高的地区在吉林东南和辽宁的东北部,五味子甲素含量较高的地区在吉林中部和河北东北部地区,五味子乙素含量较高的地区在吉林地区,五味子酯甲含量较高的地区在吉林东南和辽宁的东北部地区。综合考虑五味子中4种成分含量高低,五味子优质药材集中分布在吉林东南和辽宁的东北部地区。

This paper is aims to clarify the spatial distribution of high quality medicinal materials Schisandrae Chinensis Fructus.Based on investigation and field investigation,the samples and distribution information of Schisandrae Chinensis Fructus were collected. Based on the data of four kinds of lignin chemical constituents,ecological environment factors and spatial distribution data of Schisandrae Chinensis Fructus,using GIS technology,maximum information entropy model and SPSS statistical analysis method for regionalizing the quality of Schisandrae Chinensis Fructus. The results showed that Schisandrae Chinensis Fructus was mainly distributed in the northeast of Liaoning,east of Jilin,east of Heilongjiang. The content of schisandrin was higher in the samples from northeastern part of Jilin province and the northeastern part of Liaoning province,The content of deoxyschizandrin was higher in the samples from middle of Jilin province and northeastern Hebei province,where the content of schisandrin B was higher in the samples from Jilin area,The higher schisantherin A sample were from southeast of Jilin and northeast of Liaoning. Considering the content of four components in Schisandrae Chinensis Fructus,the quality of Schisandrae Chinensis Fructus was concentrated in the southeast of Jilin and the northeastern part of Liaoning.
