| 摘 要： | 在哈尔滨市阿勒锦岛国家湿地公园,采用样线和样方调查法,对野生种子植物进行了野外调查,研究该湿地公园野生种子植物的多样性和区系特征。在该湿地公园共记录野生种子植物58科170属272种(包括2亚种和2变种),都为被子植物。其中,物种数较多的科有禾本科(Gramineae)(48种)、菊科(Compositae)(37种)和莎草科(Cyperaceae)(21种);物种数较多的属有薹草属(Carex)(12种)、蓼属(Polygonum)(8种)和委陵菜属(Potentilla)(6种)。在该湿地公园分布着落叶阔叶林、落叶阔叶灌丛、草甸、草本沼泽和水生植被共5种植被类型,分布的植物区系主要为榆树群系(Form.Ulmus pumila)、柳属群系(Form.Salix)和芦苇群系(Form.Phragmites australis)等,与草本植物群系相比,木本植物群系的多样性水平相对较高。该湿地公园内野生种子植物区系与世界分布类型具有普遍联系,特有程度较低,在科、属、种水平上都表现为典型的温带属性,同时在种的水平上有热带、亚寒带—寒带类型植物物种的渗透。

| Abstract: | In Alejin Island National Wetland Park in Harbin,the wild seed plants were investigated by the transect method and quadrat method to study the diversity and flora characteristics of wild seed plants.The results showed that 58 families,170 genera and 272 species(including 2 subspecies and 2 varieties)of wild seed plants were recorded in this study area.All of them were angiosperm.The families,Gramineae(including 48 species),Compositae(including 37 species),Cyperaceae(including 21 species),and the genera,Carex(including 12 species),Polygonum(including 8 species),Potentilla(including 6 species)were with more species.There were 5 types of vegetation:broadleaved deciduous forest,broadleaved deciduous shrub,meadows,herbaceous marshes,and aquatic vegetation in this wetland park.Form.Ulmus pumila,Form.Salix,Form.Phragmites australis,etc.,formed the main formations.The woody formations were more abundant than the herbaceous formations in species diversity.The flora of wild seed plants in the wetland park had an extensive connection with the cosmopolitan types,and with a low degree of endemism.The main floristic components were temperate distribution type at the family,genus,species level,and there were tropical and subfrigid-frigid types infiltrated at species level. |
