【摘要】 蓼属植物抗逆性强、适应范围广,具有重要的生态价值。通过实地调查与文献查阅相结合的方法,研究了渭河河道蓼属植物资源的种类组成、观赏特性和生态特性等。结果表明:渭河河道蓼属植物资源较为丰富。调查到的蓼属植物共有12种(含变种),半直立或平卧型种类最多(50.0%),以一年生草本为主(83.3%)。依据生态类型,渭河蓼属植物可分为陆生型(66.7%)、湿生型(25.0%)以及水生型(8.3%)。研究分析其园林应用价值、生态价值、药用价值,并提出在资源保护、生态修复和园林应用三个方面的合理利用建议,为渭河河道蓼属植物资源的开发利用提供参考。更多还原

【Abstract】 Polygonum spp. were widely distributed in Weihe River and owned highly resistant property and important ecological value. Through the field investigation and literature review, the species richness, ornamental characteristics and ecological characteristics of Polygonum spp. along Weihe River were studied. The results showed that Weihe River had rich resources of Polygonum spp.. There were 12 species(including variants) of Polygonum in the survey, which were mainly semi-upright or horizontal type(50.0%), and consist mostly of annual herbs(83.3%). According to the ecological type, Polygonum in Weihe River could be divided into terrestrial(66.7%), wet(25.0%) and aquatic(8.3%) plants. Their Landscape application value, ecological value and medicinal value were listed and discussed. Finally, suggestions on reasonable utilization in three aspects were put forward, including resource protection, ecological restoration and garden application, in order to provide reference for the development and utilization of the wild plants resources of Polygonum spp. along Weihe River.更多还原
