怀地黄产地适宜性分析

为了寻找与怀地黄道地产区生态相似的区域,为怀地黄发展新产区提供科学依据,以怀地黄道地产区武陟、温县、沁阳、博爱4个县的18个乡镇为基点,通过中药材产地适宜性分析地理信息系统(TCMGIS-Ⅱ),提取基点的8个关键生态因子值,分析与其具有不同相似度的分布区域。结果表明,与怀地黄道地产区生态相似度在90%以上区域主要集中在河南、山东和河北三省交界的平原区。地黄古道地产区陕西大荔、今主产区山西曲沃等地与怀地黄道地产区武陟等地生态相似度在95%以上。为保证药材品质,建议地黄生产集中在黄淮海平原区域。

Suitability Evaluation on the Producing Area of Rehmannia glutinosa

The key ecological factors abstracted according to the TCMGIS-Ⅱ system(Traditional Chinese Medicine Geographic Information System),of 18 towns of 4 counties,Wuzhi,Wenxian,Qinyang,Boai,the geo-authentic producing area of R.glutinosa,were analysed to find the areas where climate were similar to the origin producing area of Rehmannia glutinosa in nationwide,and to provide scientific reference for the selection of its new producing area.Those areas shared similarity over 90% with that of the geo-authentic producing area of R.glutinosa centralized in the plain of the boundaries among Henan,Shandong and Hebei provinces.The climate of Dali county in Shaanxi and Quwo county in Shanxi shared high similarity over 95%.Thus,to insure the quality,the cultivation of R.glutinosa in China should centralize in Huang-Huai-Hai plain,and the TCMGIS-Ⅱ system plays an important role in the study of suitable producing area of medicinal plants.
