摘　　要：目的：明确影响沙棘的重要生态因子，分析其在我国的适宜生长地区，为民族药沙棘的引种栽培以及科学区划提供参考。方法：结合文献研究、标本查阅和野外实地采样结果，应用ArcGIS和气候数据库提取各采样点生态因子，得出沙棘适宜的生态因子范围，并以此为依据应用中药材产地适宜性分析平台（TCMGIS-域）对沙棘的生态适宜区进行分析。结果：沙棘生态相似度95%-100%的地区主要分布于西藏、四川、山西、陕西、甘肃、青海、新疆等15个省（区）387个县（市），适宜总面积为737994.71 km2。其中西藏适宜总面积之和占县（市）的比例最大，包括察隅县、江达县、波密县、八宿县、芒康县等69个县（市）（适宜面积313857.73 km2，占县（市）比例42.53%，下同）；其次为四川（223987.02 km2，30.35%）、甘肃（66314.43 km2，8.99%）、山西（4237.79 km2，0.57%）。此外，辽宁、北京、重庆和湖北等省（市）也有一定面积的适宜区分布。结论：本系统分析出了很多新的适宜区域，通过野外实地考察和田间试验，这些区域非常有可能开发成为沙棘潜在的适生区，这对沙棘的引种栽培、科学区划以及沙棘资源的可持续利用都具有重要的意义。This study was aimed to investigate the comprehensive ecological factors of Hippophae rhamnoides L. and their regional suitability in China. Based on field survey, specimen examination and literature investigation, ecologi-cal factors and appropriate production areas were analyzed by Traditional Chinese Medicine Geographic Information System （TCMGIS-II）. The results showed that the proper region （with similarity of 95%-100%） of H. rhamnoides L. accounts for 737 994.71 km2, including 15 provinces/municipalities and 387 counties/cities. The largest area among them is Tibet autonomous region with area of 313 857.73 km2 （42.53%）, followed by Sichuan province （223 987.02 km2, 30.35%）, Gansu province （66 314.43 km2, 8.99%） and Shanxi province （4 237.79 km2, 0.57%）. There are also＆amp;nbsp;certain appropriate production areas distributed in Liaoning province, Beijing, Chongqing and Hubei province. It was concluded that this system is much valuable to the recognition of the formation of the producing area, the division of adaptive area, introduction and acclimatization of medicinal materials. It also provided a scientific reference for the introduction and cultivation of H. rhamnoides L. Through further field study and experiments, these new areas have the potential to be developed into suitable production region of H. rhamnoides L. in the future.
