濒危药材肉苁蓉产地适宜性数值分析

目的：分析濒危药材肉苁蓉产地适宜性。方法：应用《中药材产地适宜性分析地理信息系统》(TCMGIS-Ⅰ),以内蒙古阿拉善盟及新疆北疆野生肉苁蓉分布区的最适宜生长环境因子为依据,分析了肉苁蓉在全国适宜产地。结果：新疆、内蒙古、宁夏、甘肃、青海5省区分布着肉苁蓉的适宜产区,共包括159个县市,总面积为675 354.9 km²。其中内蒙古阿拉善高原、新疆北疆东部、甘肃河西走廊北部、宁夏中北部是肉苁蓉适宜分布集中区。结论：肉苁蓉适宜区分析结果覆盖了第3次全国中药资源普查记载的全部区域,并且与历代本草记载的肉苁蓉产地及现代肉苁蓉引种的成功实践相吻合,证明TCMGIS-Ⅰ系统具有一定的科学性和可靠性,对濒危药材肉苁蓉的引种栽培及科学区划具有重要的参考价值。

Suitability evaluation of Cistanche desertiola based on TCMGIS-Ⅰ

OBJECTIVE: To analyze the appropriate producing area of Cistanche desertiola. METHOD: The TCMGIS-I (suitability evaluation geographic information system of traditional Chinese medicine producing area) was used to analyze the appropriate producing area of C. desertiola basing on the optimum ecological factors of Aalashan, Inner-Mongolia autonomous region and North Xinjiang au-tonomous region, the traditional producing areas of C. desertiola. RESULT: The results showed that the suitable producing areas of C. desertiola included 159 counties of 5 autonomous regions and provinces, i.e. Xinjiang, Inner Mongolia, Ningxia autonomous regions, and Gansu as well as Qinghai provinces. The total area was 675 354.9 km2 and distributed mainly in Aalashan of Inner Mongolia, eastern part of North Xinjiang, northern part of Gansu and in the middle of Ningxia. CONCLUSION: The suitable producing areas based on TCMGIS-I covered all areas registered in the 3rd national investigation of Chinese traditional medicine resource. And the results were also corresponding to the traditional producing area of C. desertiola recorded in ancient literature and the successful cultivation areas nowadays. It suggested the rationality and reliability of TCMGIS-I.
