摘　　要：以梧州园博园城市展园为对象,采用样方法对14个城市展园人工植物群落进行调查,并从群落学的角度,对样地内人工植物群落的现状进行种类组成、群落数量特征、层次结构以及生物多样性的探讨。结果表明:梧州园博园城市展园人工植物群落以常绿阔叶树为一般外貌特征,落叶树种应用数量较少;外来引种特征明显,植物地域性不强;群落结构完善,层次分明;层间植物种类单一;生物多样性指数偏低。根据调查结果,提出调整乡土植物与外来植物的种类比例、加强后期养护管理、对人工植物群落进行定期检测和长期观察的建议。Taking the city exhibition garden of the 6th(Wuzhou)Guangxi Garden&Horticulture Expo as object,this paper investigated the artificial plant communities in 14 city exhibition gardens by sampling methods and discussed the composition of plant species,quantitative characteristics of communities,hierarchical structure and biodiversity from the perspective of community science.The results showed that the artificial plant community in the city exhibition garden was characterized by evergreen broad-leaved trees,and the number of deciduous trees was less.The characteristics of introduction of exotic tree was obvious,and the regional characteristics of plants was not strong.The community structure was perfect and the level was clear;The species in interlayer plants were simple,the biodiversity index was low.According to the survey results,some suggestions were put forward such as adjusting the species proportion of native plants and exotic plants,strengthening later maintenance and management,regular detection and long-term observation of artificial plant community.
