摘要: 随着生态园林的兴起,观赏草作为一类新型的园艺植物逐渐在园林中得以推广应用。通过资料分析表明,对于观赏草的研究论文数量呈现随时间逐渐增加的趋势,并且其中一些种类如芒属、狼尾草属、蒲苇属等在资源的遗传分析、园林应用、环境适应性和抗逆性以及入侵风险性等方面有较为深入的研究。在园林应用方面,常见应用的观赏草有近百种(包括品种);但其应用范围较窄,局限于大城市以及一些经济发达地区。另外,观赏草在园林应用方面还存在着一些问题,例如培育的本土品种较少、推广应用面积较小、园林应用形式和配置手法单一。但是,观赏草以其广泛的适应性、较强的抗逆性和低廉的养护成本,将在未来的城市绿化及生态改造中发挥越来越大的功用。另外,随着观赏草的推广应用,环境的生态安全问题也日益显现,需要引起相关的注意和重视。

Abstract: With the development of ecological gardens, as horticultural plants, ornamental grasses were becoming increasingly popular and applied to landscape. Data analysis showed that published literatures on ornamental grasses increased with time, and some of the ornamental grasses, such as Miscanthus, Pennisetum and Cortaderia, were well studied on genetic resource, landscape application, environmental adaptability, resistance, and invasion risk. In terms of landscape application, approximately 100 species (including cultivars) of ornamental grasses were frequently applied, but were limited to metropolis cities or some economically developed regions. In addition, there were some problems on the application of ornamental grasses, such as few local cultivated breed, small application areas, relatively bald application forms and configuration methods. It is worth mentioning that ornamental grasses may play an important role in the application of city greening and ecological reconstruction due to their wide adaptability, low- input maintenance costs, and strong resistance. Moreover, environmental risk and ecological securities are increasingly apparent and need special attention during landscape application of ornamental grasses.
