摘要
指出了园林植物是城市生态系统的主体,也是海绵城市建设的基本要素之一,因其能够收纳及净化雨水、解决雨水面源污染及水体存储循环问题。为了丰富江门主城区海绵城市建设中城市绿化植物多样性,实地调研了江门市41个具代表性园林绿地中园林植物及乡土植物的种类及配置现状,共记录了380种(含种下单位)维管植物,隶属于107科、269属。其中乡土植物有47种,隶属于39科、42属,仅占总种数的12.36%,揭示了乡土植物在江门主城区园林绿化中的应用频度过低、品种单一、配置简单等现象,因此亟需加强园林工作者对乡土植物的重视,充分开发、利用乡土植物资源。通过实地调查、收集整理相关资料,针对江门地区生长良好、对城市环境适应力相对较强、尚待开发的乡土植物进行了统计,并初步筛选出了观赏价值较高,具一定抗性且符合海绵城市建设理念的乡土植物,为江门市主城区海绵城市建设植物选择提供一定的参考。
Garden plants are the main body of urban ecosystems , and one of the basic elements of sponge city construction, because they can contain and purify rainwater, and solve the rainwater non-point source pollution and water storage cycle. In order to enrich the diversity of urban greening plants in the construction of sponge city in the main urban area of Jiangmen, this article has investigated the types and arrangement of garden plants and native plants in 41 representative garden green spaces in Jiangmen City. A total of 380 vascular species of landscape plants belonging to 107 families and 269 genera were recorded. there are 47 species of native plants belonging to 39 families and 42 genera, only accounted for 12.36%. It reveals that the application of native plants in the landscaping of Jiangmen main urban area is too low, the few variety, and the simple configuration. Therefore, the staffs should attach importance to native plants. The author has carried out statistics on the native plants that have good growth in the Jiang men area, non-developed and relatively strong adaptability in the urban environment through on-scene investigation, collecting and collating relevant data, and initially screened out the ornamental value is high, with certain resistance and conformity. The native plants of the sponge city construction concept provide a reference for the selection of plants in the sponge city of Jiangmen City.
