摘要：湿地公园具有维持区域生态平衡、涵养与补偿水源等生态作用，以哈尔滨群力国家城市湿地公园为研究对象，对湿地公园内植物资源多样性进行调查与分析，旨在为城市湿地生态恢复与保护利用提供科学依据。采用实地调查法、样方法、资料收集法，对湿地植物资源及其生活型、生态类型、分布类型等进行研究。研究表明，群力国家城市湿地公园内共有湿地植物60科129属160种，其中被子植物56科123属151种，包含双子叶植物48科101属127种，单子叶植物8科22属24种；蕨类植物2科2属3种；裸子植物2科4属6种。科组成以分布10种及以上种的科占优势，优势科有菊科和蔷薇科；属组成以分布4种及以上种的属占优势，优势属有苹果属、槭属和蒿属。生活型分为12种，草本植物占优势，比例为58.13%。生态类型分湿生、中生和水生植物3类，湿生植物占比重最大，占湿地植物总种数的56.25%。植物科、属的分布类型分别为12个和17个，两者均以北温带分类型为主，植物区系有明显的温带性特点。

Abstract: Wetland parks have ecological functions such as maintaining regional ecological balance, conservation and compensation water source, taking Harbin Qunli National Urban Wetland Park as the research object, and investigating and analyzing the diversity of plant resources in wetland parks, aiming to restore and protect the urban wetland ecology for providing a scientific basis. The field investigation method, sample method and data collection method are used to study the wetland plant resources and their living types, ecological types, and distribution types. Studies have shown that there are 160 species of wetland plants in 129 genera and 60 families in Qunli National Urban Wetland Park, including 151 species of angiosperms belonging to 123 genera, 56 families, including 127 species of dicotyledons, 48 families, 101 genera, and 8 families, 22 genera and 24 species of monocotyledons; 2 families, 2 genera, 3 species of ferns and 2 families, 4 genera and 6 species of gymnosperms. Family composition is dominated by distribution of 10 or more species, the dominant families are Asteraceae and Rosaceae. Genus composition is dominated by distribution of 4 or more species,the dominant genera are Malus, Acer and Sagebrush. There are 12 types of living types, with herbaceous plants predominant, accounting for 58.13%. Ecological types include hygrophytes, mesophytes and aquatic plants, the largest proportion of wet plants, accounting for 56.25% of the total number. The distribution types of plant family and genus are 12 and 17 respectively, both of which are mainly divided into the northern temperate types, and the flora has obvious temperate characteristics.
