摘要
选取黑龙江省洪河国家级自然保护区作为调查区域,探究同江市湿地植物资源与区系特征。本次调查共包括102个物种,分属46科74属,莎草科植物最多,共有3属13种,而苔草属为最大属,共有物种11种。植物区系特征表明,这些植物中,北温带分布类型最为丰富,占总属数的66.67%(不包括世界分布属)。同江市湿地植物区系除受东北植物区系主导外,同时受大兴安岭、蒙古、华北区系影响。研究结果增强了人们对同江市湿地高等植物的认识,为湿地植物资源保护提供了科学依据,也为湿地植被恢复提供了数据支撑。
In this study,Honghe National Nature Reserve in Heilongjiang Province is selected as the investigation area to explore the wetland plant resources and floristic characteristics in Tongjiang City.There are a total of 46 families,74 genera,and 102 species in this survey.Cyperaceae is the largest family,with 3 genera and 13 species,and Carex is the largest genus,with 11 species.The floristic characteristics suggest that the north temperate distribution type is the most abundant,accounting for 66.67%of the total(not including world distribution).The wetland plants in Tongjiang City are dominated by Northeast China flora,and also influence by Great Khingan Mountains flora,Moongolia flora,and North China flora.This study enhances our understanding on wetland vascular plants in Tongjiang City,provides a scientific basis for protecting wetland plant resources,and also provides data support for wetland vegetation restoration.
