无纺布人工浮岛是一种无纺布与PVC管组合式植物水上栽培浮床，具有经济、易操作、稳定等优点。分析了3种不同固定方式的无纺布人工浮岛在应用中的优缺点，以及无纺布作为浮床材料的可行性和无纺布人工浮岛对水体的净化能力。结果表明：3种无纺布浮床结构中，条状无纺布框架结构操作最简单且经济；由于无纺布人工浮岛成本低、易操作，如果今后能为废弃无纺布的处置问题找到出路，无纺布人工浮岛在改善富营养化水体水质领域将会大面积推广使用。

The artificial floating island discussed in this paper is made of non-woven fabric and PVC pipes. It is economical, operation-friendly, and stable. The authors analyze the strengths and defects of three different artificial floating islands with non-woven fabric, and discuss the feasibility of non-woven fabric used as artificial floating bed material and its water purification ability. Results show that the floating bed made of strip non-woven fabric is the most convenient and economical structure. If the waste non-woven fabrics can be disposed effectively in the future, artificial floating island with non-woven fabric will be used in wide areas to improve the eutrophic water quality.
