研究城市人工林的密度与生长的关系,可以为城市绿地科学营造和管护提供依据。选择上海市浦东新区主要道路的24个绿带香樟林群落进行了调查,分析了香樟林密度与胸径、树冠、冠幅、枝下高等群落因子的相关性。结果表明:香樟群落密度与胸径及冠幅均呈显著的负相关关系;随着密度级的增大,香樟的平均高度呈现出下降趋势,但香樟林密度与高度关系不显著;香樟密度与枝下高呈正相关关系,密度越大,香樟枝下高越高;同时,群落密度过大对植株胸径、冠幅、枝下高等生长因子产生不利影响,导致植株生长势下降;而群落密度介于1200~2000株/hm2时,植物生长势较好。

The study on the relationship between urban plantation density and growth can provide a basis for the scientific construction and management of urban green space.In this paper,24 camphor forest communities in the green belt of the main roads in Pudong New Area of Shanghai were investigated,and the correlation between camphor forest density and DBH,crown,crown width and higher community factors under branches was analyzed.The results showed that the density of Cinnamomum camphora community had a significant negative correlation with DBH and crown width;With the increase of density level,the ave...
