摘要
为了解广州长隆野生动物世界植物群落结构特征及多样性,在全面踏查的基础上选取园区内有代表性的16个样地开展样方调查。结果表明:(1)园区内共有290种维管植物,共82科204属,植物种类丰富,其中大型科有6科,大型属1属;(2)园区植物群落以“乔-灌-草”为主要群落结构类型,高山榕(Ficus altissima)、小叶榕(Ficus microcarpa)、鹅掌藤(Heptapleurum arboricola)和银纹沿阶草(Ophiopogon intermedius ‘Argenteo-marginatus’)为所在层次的优势种;(3)园区的植物群落结构复杂,物种多样性丰富,在各层次α多样性指数整体特征为灌木层>草本层>乔木层,且游客活动区的植物多样性指数普遍高于动物活动区,只有乔木层的均匀度指数低于动物活动区;(4)园区共有79种乡土植物和211种外来植物,游客活动区和动物活动区的乡土树种占比均约30%,说明虽然园区内植物资源丰富,但总体上乡土树种的应用较少。本研究针对调查结果提出4点建议,以期为今后的园区改造升级提供参考。
To understand the structural characteristics and diversity of the plant communities in Guangzhou Chimelong Safari Park,this study selected 16 representative sample plots in the park to conduct a sample survey based on a comprehensive sur-vey.The results show that:(1)There are 290 species of vascular plants in the park,belonging to 82 families and 204 genera,with an abundant variety of plant species,including six large families and one large genus.(2)The plant community in the park is mainly composed of“tree-shrub-grass”,with Ficus altissima,Ficus microcarpa,Heptapleurum arboricola,and Ophiopogon intermedius‘Argenteo-marginatus’in the park being the dominant species at the respective levels.(3)the plant communities in the park have a complex structure and rich species diversity,and theα-diversity indices at each level are Shrub>Herb>Tree.The plant diversity index in the visitor activity area was generally higher than that in the animal activity area,and only the Pielou index in the tree layer was lower than that in the animal activity area.(4)There are a total of 79 spe-cies of native plants and 211 species of exotic plants in the park,and the proportion of native species in both the visitor activity area and the animal activity area is approximately 30%,indicating that although the park is rich in botanical resources,the application of native species is relatively low in general.Four suggestions are proposed as a reference basis for the subsequent renovation and upgrading of the park.
