泉州市道路绿地植物多样性研究

Study on Plant Diversity in Road Greenbelt in Quanzhou City

通过对泉州市区主要交通道路绿地植物进行详细调查,对泉州市道路绿地的植物种类、物种丰富度、频度及植物多样性进行整理与分析。结果表明:泉州市区道路绿地植物种类共有68科116种,其中木本植物91种,草本植物25种;在91种木本植物中,乔木50种,灌木41种;在50种乔木中,常绿树种34种、落叶树种16种。乔木中使用频度较高的有杧果、盆架树、小叶榕、垂叶榕、刺桐等;灌木中使用频度较高的是金叶假连翘、黄金榕、福建茶、非洲茉莉、红叶石楠等。乔木与灌木的物种丰富度指数分别为3.045、4.105,Simpson指数分别为0.597、0.633,Shannon Wiener指数分别为0.996、1.168,说明道路绿化植物的物种丰富度与种类多样性都有待提高,并对泉州城市道路绿化中的现状及存在的问题提出了相应的建议与对策。

On the basis of surveying the current afforestation situation of main roads in Quanzhou city, we systemized and ana- lyzed the plant kinds, species richness and frequency, and plant diversity in road greenbelt in this city. The results showed that there were 68 families and 116 species of plants in Quanzhou urban afforestation, including 91 species of woody plants and 25 spe- cies of herbaceous plants. Among 91 species of woody plants, there were 50 species of macrophanerophytes and 41 species of shrubs ; in 50 species of macrophanerophytes, there were 34 species of evergreens, 16 species of deciduous trees. The frequently - used macrophanerophytes included mango tree, Winchia calophyUa, Ficus microcarpa, Ficus benjamina, Erythrina indica and so on. The frequently -used shrubs included Duranta repens cv. Dwarf Yellow, Ficus microcarpa cv. Golden Leaves, Fujian tea, Fa- graea ceilanica, Photinia serrulata and so on. The species richness indexes of macrophanerophytes and shrubs were 3. 045, 4. 105 respectively, their Simpson indexes were respectively 0.597, 0.633, and their Shannon Wiener indexes were 0.996, 1. 168 respec- tively. Therefore, the species richness and plant diversity in road greenbelt should be improved. Finally, we provided some sugges- tions and based on the current situation and existing problems of urban road afforestation in Quanzbeu city.
