2013年7月至2014年2月对广州城区10个代表性公园水体的水生植物资源及应用现状进行了调查。结果表明:广州城区景观水体的水生植物共有27科56种,包括湿生植物29种、挺水植物19种、浮水植物5种和沉水植物3种;其中出现频次较高的种类有风车草(Cyperus alternifolius ssp.flabelliformis)、埃及莎草(Cyperus haspan)、菖蒲(Acorus calamus)、荷花(Nelumbo nucifera)、梭鱼草(Pontederia cordata)、再力花(Thalia dealbata)、纸莎草(Cyperus papyrus)、落羽杉(Taxiodium distichum)、睡莲(Nymphaea tetragona)等植物。调查发现广州城区景观水体水生植物应用中主要存在水生植物种类较少、造景配置单调、生态功能弱化和养护管理粗放等问题,并针对这些问题提出了相关的建议和对策。

The results showed that there were 27 families and 56 species of aquatic plants in Guangzhou urban landscape water body, including 29 species of wet plants, 19 species of emergent plants, 5 species of floating plants and 3 kinds of submerged plants. Among them, Cyperus alternifolius ssp. Flabelliformis, Cyperus haspan, Acorus calamus, Lotus flower (Nelumbo nucifera), Pontederia cordata, Thalia dealbata, Cyperus papyrus ), Taxodium distichum, Nymphaea tetragona and the like. The survey found that the main aquatic plants in the landscape water bodies in urban areas of Guangzhou City are mainly aquatic plants with few species, monotonous landscape configuration, weak ecological functions and extensive conservation and management.
