摘　　要：为给苏铁蕨(Brainea insignis)资源的保护和可持续利用提供依据,采用样线法对广东省内的苏铁蕨种群进行较全面的野外调查,测定稳定碳和氮同位素比值及碳和氮含量,对其中药饮片进行初步溯源。结果表明,苏铁蕨在广东主要分布在北江以东的惠州市、河源市、梅州市和深圳市;在北江以西分布较少;苏铁蕨分布点纬度为22°36'~24°39'N,经度为112°35'~116°48'E,海拔高度为26~706 m。2批次中药饮片的初步溯源结果显示,这些中药饮片可能源自广东罗浮山省级自然保护区、广东惠东莲花山白盆珠省级自然保护区和广东和平黄石坳省级自然保护区。In order to provide basis for conservation and sustainable use of Brainea insignis resources,more comprehensive field survey of B.insignis populations in Guangdong was carried out using sample line method.Stable carbon and nitrogen isotope ratios and contents of carbon and nitrogen were determined to preliminary trace sources of traditional Chinese medicine decoction pieces.Results showed that B.insignis mainly distributed in Huizhou,Heyuan,Meizhou and Shenzhen which were belonging to east of Beijiang River,and less distributed in west of Beijiang River.Latitude of B.insignis distribution sites ranged from 22°36'-24°39'N,longitude ranged from 112°35'-116°48'E,and altitude ranged from 26 to 706 m.Results of preliminary traceabilities of two batches of traditional Chinese medicine decoction pieces showed that they might originate from Guangdong Luofushan Provincial Nature Reserve,Guangdong Huidong Lianhuashan Baipenzhu Provincial Nature Reserve and Guangdong Heping Huangshi'au Provincial Nature Reserve.
