[Cultural regionalization for Notopterygium incisum based on 3S technology platform â ¡. Evaluation for quality suitability for N. incisum based on collocated Cokriging].

Quality characteristics based on active substance are focused for in the cultivation of traditional Chinese medicine(TCM) plants due to their economic values. However, ecological and quality suitability are not always a coincidence, which makes traditional cultural regionalization for TCM cultivation based on ecological suitability have great limitations in practical applications. A regionalization method integrated GIS and medicinal plants quality have been analyzed by using field quality data of Notopterygii Rhizoma et Radix as a case study. Spatial interpolation based on medicine quality by Cokriging method is reasonable, and the predicted values of interpolation are correlated with measured values significantly, which shows that cultural regionalization for TCM cultivation based on spatial quality suitability is possible theoretically. The results indicate that the most suitable areas for quality suitability were mainly distributed in Sichuan province (29.42%), while the spatial distribution of quality suitability and ecological suitability was not coincidence. The cultivation regionalization of TCM plants based on quality suitability is helpful to high quality and quantity cultivation of those TCM plants which spatial distribution of geoherbalism and ecological suitability is separated.
