[Potential Ecological Suitability Regionalization Analysis of Angelica sinensis Based on GIS and Fuzzy Matter Element Model].

Objective: To study the potential ecological suitability regionalization of Angelica sinensis, for protecting wild resources and selecting cultivation location and designing rational production layout.

Methods: Based on fuzzy matter element model, the relationship of fuzzy membership function between ferulic acid content and 14 ecological factors, including climate, topography and soil,were established. Then information entropy theory was used to determine the relative importance of each environmental factor, and thus to determine the most limiting habitat criteria.
