摘要：

为定量评价成都市城市园林植物群落的冠层结构，采用WinScanopy冠层分析仪和分析软件WinScanopy For Hemispherical Image Analysis对成都市区30个典型园林植物群落的冠层结构进行了定量化研究。结果表明，各样地植物群落冠层结构有显著差异。表征植物群落冠层结构的指数LAI、总空隙度、总开度、郁闭度变化范围分别在0.07~2.61、13.61%~95.81%、14.32%~88.3%、11.71%~85.68%；平均叶倾角从锐角(14.76°)到近直角(82.44°)分布。以上冠层结构指标数据的取得有助于城市园林植物群落空间结构的定量化评价和奠定城市园林植物群落冠层结构量化研究的基础，同时为园林植物群落的配置与造景设计提供科学依据。

Abstract:

In order to quantitatively evaluate the canopy structure of urban garden plant community, a study on canopy structure of typical landscape plant communities in Chengdu was conducted by using WinScanopy for Hemispherical Image Analysis. The results showed that there was significant difference on the canopy structure of plant communities among all sample plots. The range of LAI, general porosity, total opening and canopy density were 0.07-2.61, 13.61%-95.81%, 14.32%-88.3% and 11.71%-85.68%, respectively. The distribution pattern of average leaf angle changed from acute angle (14.76°) to close to right angle (82.44°). The results would contribute to the quantitative evaluation on the spatial structure of urban garden plant community and provide scientific basis for the community collocation and landscape design in urban garden plant community.
