Abstract:

The aim was to provide scientific guidance for the construction of Chinese angelica base. Using the eco-climatic data and the soil environment data of cultivated area of genuine crude Chinese angelica, the suitable index of eco-climatic and soil environment was set up by the EOF method. The results showed that the eco-climatic data and the soil environment was the leading factor in forming genuine crude Chinese angelica. The 2200 to 2400 meters above sea level of Min county and contiguous to Min county of Gansu Province were the best suitable area of cultivated area of genuine crude Chinese angelica.
