【摘要】：城市公园绿地为城市居民提供良好生活环境,也为城市生物提供适宜生境。城市绿地系统能够显著增强城市景观的自然维持能力,是城市建设的核心内容。城市公园绿地能促进城市居民与自然生物的和谐共生,提高城市生态系统的稳定性。鉴于此,城市公园绿地植物配置的研究显得尤为重要。本文选取了常德市五个公园为研究对象,就常德市公园绿地的植物配置现状进行调查分析,探索了常德市公园绿地植物群落的物种组成、植物区系分布、植物配比等方面的特点,分析了常德市公园绿地植物配置结构特点及存在的问题,同时从生态学和景观美学角度出发,提炼出了结构较为合理、功能相对完善、兼顾科学性和艺术性的植物配置优化建议,以期为常德市生态城市建设提供参考依据。本文主要研究成果如下：(1)调查表明常德市城市公园应用的园林植物种类主要有156种,属于67科124属,植物主要集中的科有樟科、木犀科、豆科、蔷薇科、木兰科、禾本科、菊科。(2)分析了五个公园的植物配置情况,并总结了每个公园的植物配置特点。(3)研究表明常德市公园绿地较稳定的乔灌木数量比为1：5,藤本植物的应用在常德市公园绿地中较为欠缺,在以后的植物选择中可适量增加。在滨水公园绿地中水生植物的应用最丰富的是白马湖文化公园。(4)常德市公园绿地中树木丰富度指数最高的是柳叶湖生态游乐园,为6.6310；多样性指数最高的公园是屈原公园,为0.8475；树木丰富度指数与多样性指数最低的均为白马湖文化公园。(5)常德市公园绿地中乡土树种与引进树种的平均数量比为1：0.64,主要应用的乡土树种有香樟、桂花、茶花、紫薇等,引进树种长势较好的有日本晚樱、黄花决明等。调查样地中观叶树种20种,观花树种26种,观果植物11种,其中常绿树种占60%。(6)常德市公园绿地植物配置模式以乔-灌-草为主,滨湖公园还适当应用了乔-灌模式,白马湖文化公园配置模式较多样化,主要以乔-灌-草和乔-草为主。
[Abstract]:Urban park green space provides a good living environment for urban residents and a suitable habitat for urban organisms. Urban green space system can significantly enhance the natural maintenance ability of urban landscape, which is the core content of urban construction. Urban park green space can promote the harmonious symbiosis between urban residents and natural organisms and improve the stability of urban ecosystem. In view of this, the study of urban park green space plant allocation is particularly important. In this paper, five parks in Changde City were selected as the research objects, and the present situation of plant allocation in the park green space in Changde City was investigated and analyzed, and the species composition and flora distribution of the plant community in the park green space in Changde City were explored. Based on the characteristics of plant matching and other aspects, this paper analyzes the characteristics and problems of plant configuration structure in Changde park green space. At the same time, from the point of view of ecology and landscape aesthetics, the reasonable structure and relatively perfect function are abstracted from the point of view of ecology and landscape aesthetics. In order to provide reference for the construction of the ecological city of Changde, the suggestions of plant allocation optimization of scientific and artistic nature should be taken into account. The main research results are as follows: (1) the investigation shows that there are 156 species of garden plants in Changde City Park, which belong to 124 genera of 67 families. The main families of plants are camphoraceae, Oleaceae, Leguminosae, Rosaceae, Magnoliaceae, Gramineae. Compositae) analyzed the plant configuration of the five parks. The results showed that the number of trees and shrubs in Changde Park was 1: 5, and the application of lianas in Changde Park Green Space was less than that in Changde Park Green Space, which could be increased in the future plant selection. The most abundant application of aquatic plants in waterfront park green space is Baima Lake Culture Park. 4) the highest tree richness index in Changde park green space is the Lancet ecological amusement park, which is 6.6310; the park with the highest diversity index is Quyuan Park. The average number ratio of native tree species to imported tree species in Changde Park was 1: 0.64. The main local tree species used were camphor, Osmanthus osmanthus, camellia, lilac, etc. Introduction of better growth tree species are Japanese late cherry, yellow flower cassia, and so on. Twenty mesoscopic leaf species, 26 flowering species and 11 fruit-watching plants were investigated. Among them, evergreen tree species accounted for 60.YU6) Arbor shrub grass was the main plant allocation pattern in Changde Park, and Arbor Irrigation pattern was appropriately applied in Binhu Park. The allocation mode of Baima Lake Cultural Park is diversified, mainly Arbor-Irrigation-Grass and Arbor-Grass.
