藏茵陈生态适宜性分析与区划

Ecological Suitability Evaluation and Regionalization of Swertiam mussotii Franch

[目的]探讨藏茵陈的适宜生态因子,并分析藏茵陈在我国的适宜生长区域,为藏茵陈规范化种植科学选址以及合理规划生产布局提供参考。[方法]以实地调查、标本查阅和文献研究为基础,采用《中药材产地适宜性分析地理信息系统》(TCMGIS)提取藏茵陈主产区的生态因子范围,并以此为依据对藏茵陈在全国的生态适宜性进行分析。[结果]获得藏茵陈主产区主要生态因子值,系统分析结果表明与藏茵陈主产区相似度高的适宜区主要位于西藏、四川、甘肃、青海等省区。藏茵陈集中生态适宜区可划分为川西高原、藏东高山-三江中段、藏南山原谷地3个亚区。[结论]利用TCMGIS-II技术开拓性地对藏茵陈的产地适宜性分析是对中药生产数值区划新的有益尝试,是将数值化定量评价引入整个传统植物区划研究领域的示范研究。

[Objective] Suitable ecological factors of Swertiam mussotii Franch were discussed,suitable growth regions of Swertiam mussotii Franch in China were analyzed,which provided a reference for standardizing planting site,as well as science and rational planning of production layout of Swertiam mussotii Franch. [Method] Based on the field survey,specimens inspection and literature review,ranges of ecological factors of main producing areas of Swertiam mussotii nationwide were extracted by using Traditional Chinese Medicine Geographic Information System （TCMGIS）,and according to this,the ecological suitability of Swertiam mussotii Franch in China were analyzed. [Result] The comprehensive ecological factors of main producing areas for S.mussotii were determined.Analysis results showed that the suitable areas with high similarities of main producing areas of Swertiam mussotii Franch were mainly located in Tibet,Sichuan,Gansu and Qinghai Provinces.Tibetan capillaris area focused on the ecological suitability can be divided into three sub-regions,including western Sichuan plateau,mountains in eastern Tibet-Sanjiang middle,Tibetan Nanshan-valley.[Conclusion] The origin suitability of Swertiam mussotii Franch was ground-breaking analyzed by TCMGIS-II technology,which was a new useful attempt for value division of Chinese medicine production,as well as a demonstration study to introduce the numerical quantitative evaluation to the division study areas of the whole traditional plants.
