摘　　要：香樟是亚热带地区的重要城市绿化树种,由于追求快速成型,人工香樟林普遍存在种类单一、密度过大、种内竞争激烈等群落结构缺陷,影响了香樟群落的稳定性和健康生长。文章选择上海滨江森林公园香樟人工林作为案例,在抽稀调整的基础上,借鉴结构化森林经营的理念和原则,提出树冠连续覆盖调整法,探讨群落结构调整与景观外貌延续有机结合的优化技术,分析调整3年后的香樟群落结构变化,为城市人工林结构调整提供参考。Cinnamomum camphora is an important urban landscape tree species in the subtropical region.Due to the pursuit of rapid shaping,the camphor plantation is characterized by a single species,large density and fierce competition among species,which have affected the stability and healthy growth of camphor.This paper chose the camphor plantation in Binjiang Forest Park in Shanghai as a case,and proposed canopy coverage adjustment method on the basis of the dilute adjustment and the concept and principles of forest management,to discuss the optimization techniques for community structure adjustment and the continuity of landscape appearance.The paper also analyzed the structural changes of camphor community 3 years later,so as to provide references for the structural adjustment of urban plantation.
