【摘要】:节约型园林是资源节约型、环境友好型社会建设的重要组成部分,是未来城市园林的发展方向。植物群落作为园林绿地景观中唯一的生命体,在园林绿化中占有重要的地位。植物群落的优化模式构建不仅可以为人们创建生态、和谐的生活环境,同时也有利于节约型社会的发展。本论文的主要研究结果如下: 本研究主要以华东沿海地区的宁波和西南内陆地区的泸州为代表,两地同属于中亚热带地区,但各具特色,选取了宁波月湖公园、鄞州公园、日湖公园、姚江公园和泸州忠山公园、滨江公园、龙透关公园为研究区域,对其中60个典型植物群落内的物种组成、树种重要值、群落类型和物种多样性进行调查分析。结果表明:宁波调查的30个样地中共有种子植物126种,隶属于55科97属;泸州调查的30个样地中共有种子植物136种,隶属于62科110属。物种组成上多以乡土植物为主,但是重要值较高的植物种类只占小部分比例,说明两地植物种类单一且贫乏。群落类型以常绿落叶阔叶混交林为主,群落结构层次简单。 通过实地调研分析,建立合理的评价体系,对60个典型植物群落从生态度、景观度和节约度三个要素上选用12个评价因子采用层次分析法进行综合评价。评价结果显示:宁波、泸州共60个植物群落综合评价等级主要集中在第Ⅱ个等级,第Ⅰ级的只有极少数几个,说明这两城市公园内优质特色群落较少,节约型城市公园植物群落仍存在较大的发展空间。在第Ⅰ级的植物群落中选择不同类型的6个典型群落作为参考模板进行了详细分析。 在上述调研和评价结果的基础上,针对目前中亚热带节约型城市公园存在的问题,提出:在植物选择上,应以乡土、节水性植物为主,,加强苗木产业开发;在群落设计上,要模拟地带性植物群落特征;在种植技术上,考虑苗木的间距和栽植季节;在养护管理上,大力发展节约型植物景观,实现园林绿化垃圾的循环利用。同时,总结提炼出节地型植物群落、节水型植物群落和节材型植物群落的优化配置模式,为中亚热带节约型城市公园绿地植物群落构建提供科学依据和技术支撑。
[Abstract]:Conservation garden is an important part of the construction of resource-conserving and environment-friendly society, and it is the development direction of urban garden in the future. Plant community, as the only living body in the landscape of green space, plays an important role in the landscape. The optimal construction of plant community can not only create ecological and harmonious living environment for people, but also benefit the development of conservation-oriented society. The main results of this paper are as follows: this study is mainly represented by Ningbo in the eastern coastal area of China and Luzhou in the inland southwest of China, both of which belong to the central subtropical region, but each has its own characteristics. Yinzhou Park, Rihu Park, Yao River Park and Luzhou Zhongshan Park, Binjiang Park and Longduguan Park were studied. Community types and species diversity were investigated and analyzed. The results showed that there were 126 species of seed plants in 30 sample plots in Ningbo, belonging to 97 genera of 55 families, and 136 species of seed plants belonging to 110 genera of 62 families in 30 sample plots of Luzhou. The species composition is mainly native plants, but the higher important value of plant species accounts for only a small proportion, indicating that the plant species in the two places are single and poor. The main type of community is evergreen deciduous broadleaf mixed forest, and the structure of community is simple. Through field investigation and analysis, a reasonable evaluation system was established, and 12 evaluation factors were selected to evaluate 60 typical plant communities by analytic hierarchy process (AHP). The evaluation results showed that the comprehensive evaluation grades of 60 plant communities in Ningbo and Luzhou were mainly concentrated in the second grade, and only a few in the first grade, which indicated that there were few high quality communities in the parks of these two cities. There is still a large space for the development of the plant community in the conservation urban park. Six typical communities of different types were selected as reference templates in class 鈪
