太白贝母生产数值区划研究

Regionalization for Growing Fritillaria taipaiensis P.Y.Li by TCMGIS-Ⅱ

本文在太白贝母的应用历史及现状调查的基础上,对其生态习性进行了文献调研和实地考察,以太白贝母分布区55个样点为分析基点,选取≥10℃积温、年平均气温、1月平均气温、1月最低气温、7月平均气温、7月最高气温、相对湿度、年均日照时间、年降水量、土壤类型等影响太白贝母生长发育的关键生态因子,再应用《中药材产地适宜性分析地理信息系统》(TCMGIS-Ⅱ)对太白贝母(Fritillaria taipaiensis P.Y.Li)在全国的生态适宜区进行分析。研究结果表明,适宜产地主要分布于陕西、湖北、甘肃、重庆、四川、云南等省区。研究结果有助于太白贝母GAP规范化种植基地选择及川贝母资源的可持续利用。

We used the suitability evaluation geographic information system of traditional Chinese medicine producing areas （TCMGIS-Ⅱ） to study the regionalization for growing Fritillaria taipaiensis P. Y. Li. 55 of distribution areas were selected as the targets for the investigation. Ten major ecological factors were chosen to determine the optimum producing area in China, including the accumulated temperature above 10 ℃, the average temperature in January, the lowest temperature in January, the average temperature, the highest temperature in July, the annual average temperature, the annual sunshine time, the annual precipitation and the soil type. The optimal districts of F. taipaiensis have been determined to be located in Shanxi, Hubei, Gansu, Sichuan and Yunnan provinces and Chongqing city. The results will be helpful to the establishment of Good Agricultural Practices and sustainable utilization for F. taipaiensis.
