| 摘 要： | 以广州市3个地点合计3 hm2的风景林样地调查数据为基础,对林隙光照与林下植物分布的关系进行了研究.多响应置换过程(MRPP)分析揭示了林下植物与林冠开度、林下直射光、林下散射光和林下总光照4种林隙光照都密切相关(P＜0.01).指示种分析(ISA)表明了林冠开度的指示种为15种,林下总光照的指示种为9种,林下直射光和...

| Abstract: | The relationships between gap light factors and understory plant species were investigated based on field survey data collected from three sample plots in urban scenic forests of Guangzhou,with a total area of 3 hm2.Multi-response permutation procedures(MRPP) revealed that understory plant species were significantly influenced(P<0.01) by four gap light factors,i.e.,canopy openness,understory direct radiation,understory diffuse radiation and understory total radiation.Indicator species analysis(ISA) detected... |
