title: [Quality Suitability of Magnolia officinalis in China Based on GIS].
abstract: OBJECTIVE
  To study the quality suitability rank dividing of Magnolia officinalis on the basis of investigation on the correlation between the ratio of magnolol and honokiol in Magnoliae Officinalis Cortex and ecological factors, in order to provide scientific basis for its planting area of high-quality medicinal materials.
  
  
  METHODS
  Based on the samples' quality analysis of 43 sampling points of Magnolia officinalis,the relationship between the ratio of magnolol and honokiol in Magnoliae officinalis Cortex and ecological factors was analyzed by statistical analysis. The geographic information system(GIS) was applied to assess the quality suitability rank dividing of Magnolia officinalis in China.
  
  
  RESULTS
  There were 12 ecological factors mainly affecting the quality of Magnoliae Officinalis Cortex; The ratio of magnolol and honokiol had obvious characteristics of regional quality. Conclusion: Magnoliae Officinalis Cortex which produced in Hubei and Chongqing is dao-di herbs.
