摘要
利用野外调查法,对哈尔滨城市湿地的植物资源概况进行了调查和统计。湿地共有种子植物62个科199个属397个种,占黑龙江省种子植物的30%左右。从科属种的组成上看,城市湿地表现出了松嫩湿地的特点。从种子植物的分布类型看,哈尔滨城市湿地具有温带湿地的性质。哈尔滨城市湿地的植物区系成分丰富,多区系成分种重叠混杂。湿地植被大体上分为2个植被型组,6个植被型,16个群系,25个群丛。湿地中的中药用、食用、蜜源和纤维等资源植物丰富,具有较高的经济价值。湿地共有国家级珍稀濒危保护植物3种:野大豆(Glycine soja)、浮叶慈菇(Sagitans natans)和浮叶慈菇(Sagitans natans)。
A survey was conducted on plant resources of urban wetlands in Harbin by field survey method. A total of 397 species of seed plants belonging to 199 genera of 62 families were recorded in the urban wetlands of Harbin,accounting for about 30% of the total seed plants in Heilongjiang Province. The urban wetlands exhibit the characteristics of Songnen wetland in terms of the composition of species,genera,and families. In the sight of the areal-types of seed plants,the urban wetlands in Harbin have the characteristics of wetlands in temperate zones. The floristic compositions are abundant,and the species of different floristic components are overlapped. The wetland vegetation can be generally classified into two vegetation type groups,six vegetation types,16 formations,and 25 associations. Abundant medicinal plants,edible plants,nectar plants,and fiber-rich plants with high economic value were observed in the wetlands. There are three species of rare and endangered plants in the wetlands,including Glycine soja,Sagittaria natans,and Nelumbo nucifera.
