中文摘要：

模拟自然植物群落、恢复地带性植被是解决城市绿地退化问题的重要途径之一。探讨植物群落结构与其美学质量的关系是在城市绿地中模拟自然植物群落成功的关键。运用心理物理学派美景度测定与统计方法之一——美景度评估法,对沈阳地带性植被广泛分布的东陵公园、北陵公园、沈阳市植物园等地进行了森林林内景观美学质量评价,同时在对植物群落结构特征调查的基础上,利用数理统计分析方法将景观美学质量和群落结构特征的各项指标相联系,系统分析了主要群落结构特征指标对景观美学质量的影响。结果显示,森林林内景观美学质量受乔木树种比例、针叶树种比例、平均胸径、灌木数量、灌木频度、灌木盖度、草本盖度等因素影响。为城市森林建设、管理以及进一步研究提供依据。

英文摘要：

Appying the scaling procedure for representing visual preference of scenic beauty,the paper investigated the visual qualities of the natural plant community by using the statistic analysis method based on the investigation of the plant community in Dongling Park,Beiling Park and Arboretum of Shenyang.The impacts of some key plant community structure characteristic indices of the scenic beauty were discussed to establish the relationship between the scenic beauty estimation and the structure characters of the plant community.The results showed that percentage of arbor,percentage of conifer,average of DBH,amount of shrub,frequency of shrub,coverage of shrub and coverage of herbage are the main factors the influence the in-forest scenic beauty.This study provided an empirically tested basis for city forest planning,management and further research in future.
