摘　　要：采用样方法,对吉林市松花江沿江绿地木本植物群落进行了调查研究。结果表明:共调查木本植物998棵,隶属于20科、34属、56种。裸子植物门中松科物种最多,被子植物门中蔷薇科物种最多。在绿化带群落乔木、灌木中东北杏、玫瑰分别具有最大的重要值,在游园群落乔木、灌木中家榆、接骨木分别具有最大的重要值,在亲水群落乔木、灌木中旱柳、茶条槭分别具有最大的重要值。Menhinick、Margalef、Shannon-Wiener和Simpson指数均表现为绿化带群落>亲水群落>游园群落,而修正的Hill指数和Pielou指数表现为亲水群落>绿化带群落>游园群落。The author investigated the species composition and alpha diversity of woody plant community in green space along the Songhua River in Jilin city through using quadrat method. The results indicated that a total of 998 woody plants were investigated, and they belonged to 56 species, 34 genera and 20 families. In gymnosperm, Pinaceae had the most species. In angiosperm, Rosaceae had the most species. Armeniaca mandshurica and Rosa rugosa had the highest importance value in green belt community; Ulmus pumila and Sambucus williamsii had the highest importance value in garden community; Salix matsudana and Acer ginnalahad the highest importance value in waterfront community. The Menhinick index, Margalef index, Shannon-Wiener index and Simpson index of various woody plant communities all showed the following sequence ： green belt community〉 waterfront community〉 garden community, while the modified Hill index and the Pielou index revealed the following order： waterfront community〉 green belt community〉 garden community.
