摘要：濕地公園具有維持區(qū)域生態(tài)平衡、涵養(yǎng)與補償水源等生態(tài)作用，以哈爾濱群力國家城市濕地公園為研究對象，對濕地公園內(nèi)植物資源多樣性進行調(diào)查與分析，旨在為城市濕地生態(tài)恢復(fù)與保護利用提供科學(xué)依據(jù)。采用實地調(diào)查法、樣方法、資料收集法，對濕地植物資源及其生活型、生態(tài)類型、分布類型等進行研究。研究表明，群力國家城市濕地公園內(nèi)共有濕地植物60科129屬160種，其中被子植物56科123屬151種，包含雙子葉植物48科101屬127種，單子葉植物8科22屬24種；蕨類植物2科2屬3種；裸子植物2科4屬6種。科組成以分布10種及以上種的科占優(yōu)勢，優(yōu)勢科有菊科和薔薇科；屬組成以分布4種及以上種的屬占優(yōu)勢，優(yōu)勢屬有蘋果屬、槭屬和蒿屬。生活型分為12種，草本植物占優(yōu)勢，比例為58.13%。生態(tài)類型分濕生、中生和水生植物3類，濕生植物占比重最大，占濕地植物總種數(shù)的56.25%。植物科、屬的分布類型分別為12個和17個，兩者均以北溫帶分類型為主，植物區(qū)系有明顯的溫帶性特點。

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.
