- 分享到:
摘要：
以荆州古城分布的主要公园绿地为调查对象,共选取样方数86个,利用植物物种丰富度指数、均匀度指数、重要值以及多样性指数等指标对荆州古城公园绿地植被群落进行调查分析.结果表明,调查区内有301种维管植物和人工栽培植物165种,隶属于71科107属;野生植物136种,隶属于56科113属.植物种类主要由本地乡土树种组成,其中223种为当地树种,占被调查的绿地植物总数的74.1%.樟树、构树、红檵木、红叶石楠、狗牙根和马尼拉为优势种.植物多样性由高到低表现为草本层、乔木层、灌木层.综合公园丰富度指数、多样性指数和均匀度指数均高于其他类型公园绿地,植物群落结构丰富.荆州古城绿地植物重复使用频率较高,分布区域不均衡,地域特色不明显.
The main park greenbelts distributed in ancient city Jingzhou were taken as the survey object.A total of 86 sample areas were selected out of the main parklands,and the plant species richness index,important value,diversity index and evenness index were used to investigate and analyze the vegetation communities in the ancient city park of ancient Jingzhou.The results showed that there were 301 species of vascular plants in the survey area,165 species of cultivated plants,under 107genera of 71 families.The wild plants are 136 species belonging to 113 genera of 56 families.The plant species are mainly composed of local indigenous trees,of which 223 species are local trees,which are accounting for 74.1%of the total surveyed green space plants.There are 6 dominant species in the survey,such as Cinnamomum camphora,Broussonetia papyrifera,Loropetalum chinense,Photinia fraseri,Cynodon dactylon and Zoysia matrella.The species richness of the urban green spaces were characterized from high to low in the order of herbaceous layer,treelayer,shrublayer.The richness index,diversity index and evenness index of the comprehensive parks are all higher than other types of park greenbelts,and the plant community is rich in structure.The vegetation in the ancient city of ancient Jingzhou has a high frequency of repeated use,uneven distribution area and non-obvious regional features.
