| 摘要: |
| 以上海“城-郊”样带上不同用地类型的香樟为研究对象,通过固定样方调查香樟的受光面,以及反映香樟生长状况的生物学特征.结合数理统计方法,分析香樟树冠受光面对其生长的影响.结果显示：公共绿地类型香樟受光面等级较多集中于1级和5级,建设绿地受光面等级多集中在3级；香樟是一种重要的经济和生态植物,公共绿地中的香樟树冠比较广阔,建设绿地中的香樟树木密度相对更高；不同等级受光面对植物生长特性影响是显著的,与树高之间的相关性最高. |

| Abstract: |
| In this paper,the effect of crown light exposure on the growth of Cinnamomum camphora in different land types in the “urban-suburban” sample zone in Shanghai was investigated,for which the biological characteristics was analyzed through fixed samples,combined with mathematical and statistical method. The results showed that： the crown light exposure classes of Cinnamomum camphora in public green space types were more concentrated in 1 and 5,while the crown light exposure classes of Cinnamomum camphora in construction green space were more concentrated in 3； Cinnamomum camphora was an important economic and ecological plant,and the canopy of it in public green space was more extensive,while the tree density in construction green space was relatively high； the influence of different classes of crown light exposure on plant growth characteristics was significant,and the tree height became the most correlative factor for the crown light exposure. |
