黑龙江省野生维管植物名录

Checklist of tracheophyte in Heilongjiang Province

黑龙江省位于中国的东北端,省下辖区划分复杂而繁多,植被可分为3大区域:寒温带针叶林区域、温带针阔混交林区域、温带草原区域。本名录主要参考《中国生物物种名录(2021版)》《东北植物志》《东北植物检索表》《黑龙江省植物志》《黑龙江省树木志》《东北植物分布图集》《东北草本植物志》等著作、近年来发表的论文和来自国家标本资源共享平台(NSII)、全球生物多样性信息网络(GBIF)、东北林业大学植物标本室(NEFI)、东北农业大学生命科学学院植物标本室(NEAU)、中国科学院沈阳应用生态研究所东北生物标本馆(IFP)的标本资料以及最近发表的文献资料。由于“无分布”比“有分布”的信息相对较难确定,我们在整理数据时,轻易不删除重要著作中已经有收录的物种,除非有较可信的证据,这可能使得本数据集的物种数量稍偏多。本名录中物种分布精确到县级,共收录黑龙江省野生维管植物132科651属2,276种(亚种、变种),有凭证标本的本土植物2,122种(亚种、变种),广泛入侵的44种,无凭证标本但是有较可靠资料的154种。其中石松类2科6属17种,蕨类植物16科34属81种,裸子植物3科6属20种,被子植物111科605属2,158种。收录国家级重点保护植物22科25属39种。黑龙江野生维管植物中,菊科(67属258种)、禾本科(61属187种)、莎草科(14属174种)、毛茛科(18属124种)和蔷薇科(24属112种)所含种数较多。统计发现,黑龙江省物种县域分布差异较大,131个县级行政单位中,物种数超过1,000的约占1/6,且县级分布数据严重不均衡。本名录中,省级名录的可信度相对较高,县级分布数据质量还需要大大提升。

Background&Aim:A high-quality checklist is of great significance to plant taxonomy,ecology,geography,and the utilization of plant resources.Unfortunately,since the 1980s,the checklist of Heilongjiang Province has not been fully updated for a long time,which has seriously hindered related research.This paper attempts to obtain a credible province-wide checklist and county-level plant distribution data.Method:The TNRS(Taxonomic Name Resolution)was used to correct the spelling of scientific names.And the scientific name adopts the viewpoints in the Catalogue of Life China(2021).The checklist mainly refers to documents,i.e.Catalogue of Life China(2021),Key of Plants of Northeastern China(2nd edn),Flora of Heilongjiang,Ligneous Flora of Heilongjiang,Distribution Atlas of Northeast China Plant,Flora Plantarum Herbacearum Chinae Boreali-Orientalis,some articles and specimen data(from NSII,GBIF,NEFI,NEAU,IFP)to locate the species distribution in county-level divisions.Results:A total of 2,276 species(subspecies and varieties)belonging to 651 genera and 132 families of tracheophyte in Heilongjiang Province were counted,including 17 species belonging to 6 genera and 2 families of lycopods,81species belonging to 34 genera,and 16 families of pteridophytes,20 species belonging to 6 genera and 3 families of gymnosperms,and 2,158 species belonging to 605 genera and 111 families of angiosperms.Among them the families of Asteraceae(67 genera,258 species),Poaceae(61 genera,187 species),Cyperaceae(14 genera,174 species),Ranunculaceae(18 genera,124 species)and Rosaceae(24 genera,112 species)contain a large number of species.This checklist shows remarkable differences in species distribution among counties in Heilongjiang Province.About 17percent of 131 counties have more than 1,000 species,and the county-level distribution data are seriously unbalanced.Conclusions:The provincial checklist is reliable,but the quality of county-level distribution data needs to be significantly improved.
