Habitat Suitability Evaluation of Polygala tenuifolia Based on MaxEnt Model and ArcGIS
Polygalae Radix is mainly produced in Northeast,North,Northwest and Central China and Sichuan province. There are obvious differences in quality of
Polygala tenuifolia
from different areas.
P. tenuifolia
cultivation areas are relatively concentrated. Currently,there are only a few studies about the suitability zoning of
P. tenuifolia
nationwide,in order to determine the suitable zoning of
P. tenuifolia
in China. This paper made a habitat suitability evaluation of
P. tenuifolia
nationwide based on analysis of ecological factors in distribution areas of sampling points.
Method
2
MaxEnt model was used to select ecological factors that affected the distribution of
P. tenuifolia
and construct an evaluation model. ArcGIS software was used to evaluate the suitability of different habitats of
P. tenuifolia
. The suitable areas were classified into high,medium,low suitability areas and unsuitable area of
P. tenuifolia
nationwide.
Result
2
The evaluation model was highly accurate,and concluded that
P. tenuifolia'
s suitability distribution area in China was 3.21×10
6
km
2
,including 0.52×10
6
km
2
of high suitability area,0.96×10
6
km
2
of medium suitability area and 1.73×10
6
km
2
of low suitability area. High suitability areas were mainly distributed in Shanxi province,Hebei province,Shandong province,Shaanxi province,Liaoning province and Henan province. The main ecological factors affecting the distribution of
P. tenuifolia
were annual average temperature change range,mean temperature of driest quarter,precipitation of wettest quarter,altitude,slope and topsoil (0-30 cm) calcium carbonate.
Conclusion
2
The results of the study are consistent with the records in relevant literatures,and can provide a theoretical basis for protection and cultivation of Chinese medicine resource
