摘要
森林公园因有较高的生态效益,是城市绿地中发挥森林功能,特别是发挥森林生态服务功能主要的载体。为深入了解南宁市植物种类资源与景观现状,对地处南宁市五象新区的五象岭森林公园进行全面的植物种类调查、统计与分析,并对其景观营造效果进行评价。结果显示:南宁市五象岭森林公园共有维管束植物341种,隶属于103科,266属,其中,豆科(Fabaceae)、禾本科(Gramineae)、菊科(Asteraceae)、大戟科(Euphorbiaceae)、桑科(Moraceae)、锦葵科(Malvaceae)、叶下珠科(Phyllanthaceae)和樟科(Lauraceae)为优势科;公园内植物的生活型丰富,乔灌草藤均有;可用观赏植物种类丰富,占所有植物种类总数的47.8%;所有植物种中乡土植物共有62种,外来植物共有279种,分别占植物总数的18.18%和81.82%。但南宁市五象岭森林公园也存在一些问题,如园内主要树木类型为马尾松、湿地松及桉树林等人工林,导致公园景观结构不合理;同时园内乡土植物仅有62种,占比偏低,地域特征不明显;落叶植物种类不足,秋冬季可观景色缺乏等。针对上述不足,建议采取合理增加本土观赏植物应用比例、间伐等措施改善人工林林分结构,构建层次丰富的植物群落,同时通过加大垂直绿化植物的应用等措施进行改善。
Forest parks have good eco-efficiency.It is the prime carrier to give full play to the forest ecological services in urban areas.WuXiangLing Forest Park is located in the Wuxiang New Area of Nanning City.This study conducted a compre-hensive survey,statistics,and analysis of plant species and evaluated their landscape to determine their plant species resources and landscape status.The results show 341 species of vascular plants belonging to 103 families and 266 genera in the park.Among these plants,Fabaceae,Gramineae,Asteraceae,Euphorbiaceae,Moraceae,Malvaceae,Phyllanthaceae,and Lauraceae are the dominant families.The park has a complete range of plant life types,with four types of life types:trees,shrubs,herbs,and vine plants.There are abundant available ornamental plants,accounting for 47.8%of all plant species.Among all species,62 are native plants,and 279 are exotic plants,accounting for 18.18%and 81.82%of the total number of plants,respectively.However,some existing problems cannot be ignored.For example,the landscape structure is unreasonable because the main tree types in the park are artificial forests such as horsetail pine,wetland pine,and eucalyptus forest.At the same time,there were 62 species of native plants in the garden,and the proportion of native plants low,and the regional characteristics were not distinct.The species of deciduous plants are insufficient,and the scenery in autumn and winter is poor.Given the above deficiencies,it is suggested that the proportion of local ornamental plants should be increased,and the structure of the plantation should be optimized through thinning and other measures to build a plant community with a rich hierarchical structure.
