武汉市水生植物资源调查及其应用现状

抽取武汉市几个典型的城市湿地,对其主要水生植物的种类、分布、应用进行了调查和分析。结果表明:武汉市水生植物种类主要为挺水植物、浮水植物(包括浮叶和漂浮)、沉水植物,就其植物种类而言,沉水植物最多,共有44种,挺水植物其次,共有41种,而浮水植物最少,只有25种。调查发现在武汉市水生植物应用中存在的主要问题是水生植物应用种类及范围不够、配置单调、管理缺乏、生态问题研究不够、设计人员认识不足等,针对这些问题提出了建议和对策。

Resources Investigation and Current Situation of Application of Aquatic Plant in Wuhan City

Several typical urban wetlands in Wuhan have been selected,and the investigation and analysis on the species resource,distribution and application of aquatic plant have been carried out.The results showed that the main aquatic plant type in Wuhan were emergent plants,floating plants(including floating leaves and floating drift)and submerged plants,in which submerged plants had 44 types,emergent plants had 41 types,and floating plants had only 25 types.There were some prominent problems in application of aquatic plant,such as less species,limited applica tion scope,monotonous configuration,lack of management,not enough research on ecological prob lems,insufficient knowledge of designers,and so on.Put forward some suggestions and countermea sures in accordance with these problems.
