[Objective]The distribution of common wild plant germplasm resources and their life form characteristics in Hinggan League were investigated and analyzed to provide a reference for the protection,rational development and utilization of wild plant resources.[Method]The geographical distribution range,habitat characteristics,species and life form characteristics of common wild plant germplasm resources in Hinggan League were investigated and analyzed by the field survey method and indoor identification.[Result]A total of 240 common wild plant germplasm resources were collected in Hinggan League area,of which 173 were non-repetitive species,belonging to 40 families and 121 genera.The collection comprised 47 copies of perennial grass germplasm resources,26 copies of shrubs,sub-shrubs and small trees,115 copies of perennial miscellaneous grasses,and 52 copies of 1-2 year-old herbs.The seeds of perennial miscellaneous grasses constituted the most abundant category,representing 46.96% of the total collected seeds,followed by the seeds of 1-2 year-old herbs,accounting for 21.67% .The seeds of perennial grasses and shrubs,sub-shrubs and small trees were less abundant,representing 19.58% and 10.83%,respectively.[Conclusion]With regard to geographical distribution,perennial grasses are predominantly found in Ulaanhot City,shrubs,sub-shrubs and small trees are primarily located in Jalaid Banner and Arxan City,and perennial miscellaneous grasses and 1-2 year-old herbs are mainly distributed in Jalaid Banner,Arxan City,Horqin Right Wing Front Banner and Horqin Right Wing Middle Banner.
