对福州市辖区内自1995年建成的36个居住区景观树木构成和物种多样性进行调查，并根据建成年代和相对城市环线位置进行分析。结果表明，36个居住区共有155种12 694株景观树木，隶属于42科和97属。在树种构成分析中，将树种按常见程度分为6个组，标志组有20种，共7560株，优势组、常见组、少见组、稀有组以及孤生组分别有17、19、49、38、12种和2383、1297、1269、173、12株。多样性分析表明，福州市居住区景观树木多样性与发达城市比较还存在差距，尤其是旧居住区的景观树木物种多样性更低，树种选择也更为单一。此外，取样居住区中部分安置房居住区的景观树种多样性低于同时期非安置房居住区。
This study evaluated species composition and floristic diversity of landscape trees in 36 housing estates in Fuzhou. There were 12 694 trees belonged to 155 species, 97 genera and 42 families. The species were divided into 6 frequency groups. 20 species with 7560 trees were in the Signature group. The Dominant, Common, Occasional, Rare and Solitary groups contained 17, 19, 49, 38 and 12 species with 2383, 1297, 1269, 173 and 12 trees respectively. The landscape trees in Fuzhou showed lower biodiversity indexes, especially species richness, compared to developed cities. The landscape trees in aged estates and relocation estates were with lower biodiversity than those in other new estates.
