【摘要】 随着城市的发展,城市环境建设越来越受到人们的重视,城市园林绿地在其中的地位也进一步提升。无锡市是太湖流域的交通枢纽,被誉为“太湖明珠”,风景秀丽,历史悠长。无锡市致力于建设国家生态园林城市,并以城市绿地建设作为重要任务。借助《城市园林绿化评价标准》颁布之际,无锡市园林局敏锐的把本地木本植物作为重点建设项目,并进行了实质性的研究。评价标准中提出了对本地木本植物的一系列要求,本文以此为契机,系统地探讨了本地木本植物在城市绿地中的应用。本文根据《中华人民共和国城市绿地分类标准》(CJJ/T85-2002)选取了城市绿地中公园绿地、附属绿地、其他绿地等三类绿地中的18个样地54个样方进行了木本植物的调查。并从木本植物的种类组成出发,对本地木本植物的群落特征、指数情况和本地性进行了详细分析。主要结论如下：(1)本地木本植物种类及应用数量研究。18个样地中出现的本地木本植物186种,隶属于56科118属。乡土植物102种,归化种有14种,驯化种70种,整体呈现出乡土植物为主,驯化种为辅的现象。无锡市城市绿地中的木本植物,主要是由香樟、朴树、桂花、鸡爪槭、毛鹃、小叶女贞等组成,这些物种在多度、频度或综合优势度比中都占很大优势,尤其是香樟和桂花,应控制性的运用。(2)本地木本植物指数研究。无锡市城市绿地的本地木本植物指数为0.92,达到了城市园林绿化评价标准中城市园林绿化Ⅰ级评价标准。分析表明,大类绿地中G4类绿地的指数较小,尤其是其中的G41类绿地；行政区中新区的本地木本植物指教较小。同时发现无锡市城市绿地中本地木本植物的重复现象严重,归化种种类较少。(3)无锡市城市绿地本地木本植物应用优化建议。针对无锡市城市绿地中本地木本植物种类、应用数量及本地木本植物指数的研究,对无锡市城市绿地的构建提出了优化建议。其中增加城市绿地中的乡土植物是根本途径,指导性并有控制性的使用外来植物是重要措施。此外,建议建立本地木本植物监测与养护管理体系,为更好的使用本地木本植物提供保障。更多还原

【Abstract】 With the development of the city, the urban environment has aroused widespread attention, and the positiong of the urban green land is more and more important. Wuxi city is a hub of communications in the Taihu lake basin, and is known as "the pearl of Taihu lake". Wuxi has beautiful scenery and long history.Wuxi is committed to building national ecological garden city, and takes the construction of urban green space as an important task. Along with the urban landscape evaluation standards promulgated, Wuxi sharped developed local woody plant project. This paper takes this opportunity to systematically discuss the application of local woody plants in urban green space.According to the law of Standard for classification of urban green space, this article selects the park green space, attached green space and other green space. The investigative areas include18sample plots and54quadrats. Based on the composition of local woody plant, detailly analyze the phytocoenology and local woody plant index. The main results are as follows:(1) The composition and community characteristic of local woody plant. There are186types of woody plants which belong to56families and118apecies. The local plants are102species, naturalized species are14types, and domesticated species are70types. It presents the local plant is priority and domesticated specie is secondary. The Wuxi urban green space is consisted of Cinnamomum camphora, Celtis sinensis, Osmanthus fragrans, Acer palmatum, Rhododendron pulchrum and Ligustrum quihoui, which are advantage in abundance, frequency and summed dominance ratio. The Cinnamomum camphora and Osmanthus fragrans should be controlled.(2) The study of local woody plant index. The local woody plant index of Wuxi is0.92, which is up to the standard. The analysis result indicates the the local woody plant index of G4green space is the least, especially the G41green space. In the four administrative areas, the index of Xinqu is least. It also finds that the recurrence phenomenon of local woody plants is serious, and the type of naturalized specie is poor.(3) The suggestions of improving Wuxi urban green space. The basic solution is increases the species of local plants, and the important solution is controlled use the exotic plants. In addition, in order to offer better guarantee, it is suggested that build monitor and maintennace management system for locan woody plants.更多还原
