摘要：为探究吉林省查干湖地区植物资源组成及其区系特征,对查干湖地区野生维管植物的资源组成、生活型谱、水分生态类型及区系地理成分进行分析研究。结果表明,吉林查干湖地区共有野生维管植物578种,隶属于79科283属,其中包括蕨类植物2科2属4种,裸子植物2科2属2种,被子植物75科279属572种;其生活型谱可划分为5种类型,以多年生草本植物为主,共364种植物,占物种总数的62.98%;水分生态类型可划分为8种类型,以典型中生植物为主,共267种植物,约占物种总数的46.19%;植物区系地理成分划分为10个一级分布区类型,以东古北极分布种为主,共189种植物,约占物种总数的32.70%;查干湖地区野生维管植物可划分为食用植物、药用植物、饲用植物、纤维植物、观赏植物、生态功能植物、有毒植物、其它资源植物共8种类型,其中药用植物资源最为丰富,约占物种总数的76.12%。研究表明,吉林查干湖地区野生维管植物资源丰富,物种组成、生活型谱、水分生态类型以及地理区系均具有明显的多样性,通过对区域内植物资源的全面梳理和系统分析,为该地区的野生植物资源保护及合理利用提供重要的科学依据。
In order to explore the plant resource composition and floristic characteristics of the Chagan Lake Area in Jilin Province,the resource composition,life form spectrum,water ecotypes and floristic geographic compositions of wild vascular plants in the Chagan Lake Area were analyzed.The results showed that there were 578 species of wild vascular plants belonging to 79 families and 283 genera,including 4 species of ferns belonging to 2 families and 2 genera,2 gymnosperms belonging to 2 families and 2 genera,and 572 species of angiosperms belonging to 75 families and 279 genera.The life form spectrum could be divided into 5 types,mainly perennial herbs,with 364 species,accounting for 62.98%of the total species.Water ecotypes could be divided into 8 types,mainly typical mesophytes,with 267 species,accounting for 46.19%of the total species.The floristic geographic compositions were divided into 10 primary distribution types,mainly the East Palaearctic elements,with 189 plant species,accounting for 32.70%of the total species.Wild vascular plants in Chagan Lake could be divided into 8 types:edible plants,medicinal plants,feeding plants,fiber plants,ornamental plants,ecological functional plants,poisonous plants and other resource plants.Among them,medicinal plants were the most abundant,accounting for 76.12%of the total species.The study showed that the wild vascular plant resources in Chagan Lake Area of Jilin Province were abundant,with obvious diversity in species composition,life form spectrum,water ecotype and geographical flora.Through comprehensive sorting and systematic analysis of plant resources in the region,it provided an important scientific basis for the protection and rational utilization of wild plant resources in the region.
