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.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.
