Abstract:
Objective: To study the ecological suitability of Angelica sinensis growing in Gansu Province and guide the rational cultivation. Methods: Through visiting and field investigation, 1 545 batches of Chinese angelica samples were collected from the county areas in Gansu Province. The information about the longitude, latitude, altitude of each sampling point was collected by using the GPS, combining with national environmental factor data, and using Maxent model and spatial analysis function of ArcGIS software. Results: The areas with high suitability of A. sinensis distribution are in the southeast of Gansu Province. The main ecological factors affecting the suitability distribution of A. sinensis were altitude, rainfall in March, May and December, wettest month precipitation, soil pH and other ecological factors. Conclusion: The research findings are basically consistent with the living habits of A. sinensis that cultivated in high-cold mountain areas and plateau flat pasture areas with a cool climate, moderate soil, moisture, slightly acidic to neutral fertile and loose brown sandy loam soil. This result can provide scientific basis for the reasonable distribution of A. sinensis cultivation area in Gansu Province.
