Objective: To analyze the appropriate producing area of Capparis spinosa. Method :The TCMGIS(suitability evaluation geography information system of traditional Chinese medicine producing area)was used to analyze the appropriate producing area of C. spinosa basing on the optimum ecological factors of Turpan

east Xinjiang autonomous region and South Xinjiang autonomous region

the traditional roducing areas of C. spinosa. Result: The results showed that the suitable producing areas of C. spinosa included 183 counties of 5 autonomous regions and provinces

i.e. Xinjiang
