摘 要:
利用样方法调查了沈阳市5种城市森林类型200个样方的木本植物分布，对其物种多样性进行分析，结果表明：沈阳城区的物种多样性以风景游憩林最高，并且与其他类型相比存在极显著差异；附属林的多样性表现次之，与其他类型相比存在显著差异；道路林、生态公益林和生产经营林之间的物种多样性之间没有极显著差异，但存在部分显著差异，其中生态公益林的物种多样性最低。沈阳城市森林各类型之间树木分布较为均匀，各类型间存在的差异主要取决于物种的丰富度。[著者文摘]

Abstract:
Surveys on distribution of woody plants of 5 urban forest types in 200 plots by sample methods in Shenyang were conducted, and analysis of its species diversity was also carried out. The results indicated that： in Shenyang urban areas, the species diversity of Landscape and Relaxation Forest. （L） was the highest and was different significantly compared with other types; the species diversity of Subordinated Forest（S） was higher and was different significantly compared with other types. The differences among Road Forest（R）, Production and Management Forest（P） and Ecological ＆ Public Welfare Forest（E） were not significant but partial difference existed. Ecological ＆ Public Welfare Forest （E） had the lowest diversity. The trees of urban forest types distributed well- proportioned and species diversity difference was mainly due to species richness.[著者文摘]
