    重庆主城区屋顶绿化乡土植物资源调查及其应用分析

    Resource investigation of roof greening native plant of Chongqing main city and its landscape application analysis

    • 摘要: 植物多样性是生物多样性的组成部分, 而园林植物则是城市生态系统的主体, 城市生物多样性的维持依赖于多样化的城市植物, 乡土植物恰恰是城市植物的重要组成部分, 更是城市植物景观特色构建的必要条件。为了丰富重庆主城区屋顶植物多样性, 本文采用抽样调查的方法, 以重庆主城区31处不同屋顶绿化作为样方, 进行实地调查并从植物类型、配置方式、观赏特性3个层面进行研究分析, 从而判断导致重庆地区屋顶绿化中乡土植物应用频度低的薄弱环节。调查显示样方中应用的植物共有110种, 隶属47科76属, 但乡土植物仅占13.64%, 隶属14科15属。从以上3个层面进行数据统计, 均存在乡土植物种类少、应用频度低的现象。因此加强园林工作者对乡土植物的重视, 开发利用这些乡土植物是当务之急。结合以上研究及对相关资料的收集、整理, 针对在重庆野外均生长良好、对城市环境适应力相对较强、可供近期开发的乡土植物进行了统计, 并初步筛选出观赏价值较高, 且适合应用于重庆地区屋顶绿化的乡土植物, 其中着重增加了草本及观果、观花乡土植物, 在准确掌握其生物学特性及观赏特点、生态习性及适生范围等方面的前提下, 可以逐步应用于屋顶绿化, 从而为重庆地区屋顶绿化及乡土植物发展提供科学依据。

       

      Abstract: Plant diversity is important component of biodiversity, and garden plants are the main parts of urban ecological system. The maintenance of urban biodiversity depends on the diversity of urban plants, native plants are important part of urban plants, even the necessary condition of making characteristics of urban plant landscape. As for the abundant resources of native plants in Chongqing of southwestern China, aim at weakness in the application of native plants in roof greening, we did survey of 31green roofs of central districts of Chongqing by sample survey. We got that there were 110 species of plants. Then we summarized and analyzed the characteristics of roof plants in application and configuration, frequency, ornamental value and so on. But native plants only accounted for about 13.64%. After summarized datum in the 3 levels, we got a phanomenon that the species and application frequency of native plants are relatively few. Therefore, the staffs should attach importance to native plants. It is imperative to exploit native plants. Based on the results, a list of native plants for developing and popularizing were suggested. We should be aware of their characteristics and gradually being applied to roof greening. Finally, the strategy and suggestion are proposed on the protection and exploitation of native plant resources, and the construction of urban green space using these resources in Chongqing City.
