乌龙江公园植物多样性调查研究
Investigation and research on plant diversity in Wulongjiang Park
摘要
Abstract
[Objective]This study aims to clarify the plant resource characteristics of Wulongjiang Park,evaluate its landscape composition,and propose scientific optimization strategies to address existing issues.[Method]Field surveys and line-transect methods were adopted to record information on plant species names,quantities,life forms,etc.Statistical analyses were conducted on the composition of families,genera,and species,along with an assessment of their diverse ornamental characteristics.[Result]The results show that Wulongjiang Park hosts 226 landscape plant species,belonging to 166 genera and 73 families.Angiosperms dominate,comprising 69 families,161 genera,and 220 species,while gymnosperms include 3 families,4 genera,and 5 species,and ferns consist of 1 family,1 genus,and 1 species.Life-form analysis indicates that trees are predominant.The family and genus distribution patterns are relatively scattered,with single-species families and genera being most common,reflecting high diversity.In terms of plant origin,introduced species prevail.Regarding ornamental value,landscape plants are ranked in the following order:multi-purpose ornamental plant＞foliage plants>flowering plants>form plants>fruit plants.In terms of invasive status,a total of 7 alien invasive plant species were identified,belonging to 4 families,with Verbenaceae accounting for 3 species(42.86%).From the perspective of geographical origin,there are 3 types.Among them,species from tropical America are the most abundant,with 6 species,accounting for 85.71%.According to the hazard classification,there are 2 species classified as Level Ⅰ,2 as Level Ⅱ,1 as Level Ⅲ,and 2 as Level Ⅴ.[Conclusion]Wulongjiang Park exhibits rich plant diversity and high ornamental value.The findings of this study can provide scientific references and baseline data for the planning,construction,and ecological management of similar wetland parks.关键词
