观赏草作为园林绿化常用材料,具备良好的耐盐耐碱特性,在滨海盐碱地生态修复与综合利用中具有重要应用价值。本文聚焦耐盐观赏草在滨海盐碱地的应用,系统梳理了耐盐观赏草的种类与耐盐能力,明确其涵盖狗尾草、荻和芦苇等乡土野生品种,以及蓝滨麦、芨芨草等人工选育品种,其中芨芨草、二色补血草等可适应含盐量>6%的盐碱区域,苜蓿、星星草等可作为滩涂植被重建先锋物种;分析了其生态修复效应,包括通过生理代谢改良土壤理化性质(如柳枝稷可使土壤有机质含量提升、土壤盐分含量降低)、固土护坡及提升生物多样性等;探讨了其综合利用场景,涵盖景观绿化(应用于滨海公园等场景)、生态产业融合(生态观光等产业链)、生态工程应用(滩涂治理等)多个层面;最后对耐盐碱观赏草品种选育、滨海盐碱地利用方式转变等研究方向进行展望。本文为观赏草资源化利用提供参考。

Ornamental grasses, as common materials for landscape greening, exhibited desirable salt and alkali tolerance and had important application values in the ecological restoration and comprehensive utilization of coastal saline‑alkali land. This study focused on the application of salt‑tolerant ornamental grasses in coastal saline‑alkali areas, systematically sorted out their species and salt tolerance levels, and identified that they contained native wild, such as Setaria viridis, Triarrhena sacchariflora, and Phragmites australis, and artificially bred varieties, such as Leymus arenarius and Achnatherum splendens. Among them, Achnatherum splendens and Limonium bicolor adapted to saline‑alkali areas with a salt content higher than 6%, while Medicago sativa and Puccinellia tenuiflora acted as pioneer species for vegetation reconstruction in tidal flats. The ecological restoration effects were analyzed, including the improvement of soil physical and chemical properties through physiological metabolism. For example, Panicum virgatum increased soil organic matter content and reduced soil salinity. These plants also realized soil consolidation, slope protection and biodiversity enhancement. This paper explored their comprehensive utilization scenarios involving multiple dimensions, including landscape greening in coastal parks and similar sites, ecological industry integration represented by eco‑tourism industrial chains, and ecological engineering applications such as tidal flat management. Finally, the research prospects were proposed, covering the selective breeding of salt‑alkali tolerant ornamental grasses and the transformation of utilization modes for coastal saline‑alkali land. The relevant results provided a reference for the resource utilization of ornamental grasses.
