摘　　要：通过对空心莲子草和三棱草进行漂浮栽植,分别研究了他们在单独种植和混合种植方式下对低、中、高3种盐度的海岛含盐河道水质的生长状况和净化效果。结果表明:2种种植方式下的植物都在3种盐度中正常生长,且在低、中盐度水中的生长状况均优于高盐度的。2种种植方式下2种植物都能有效净化海岛高含盐水质,其中对NH4+-N、TIN和PO43--P的去除率均以单独种植空心莲子草的去除效果最好,最高去除率分别可达到32.86%、31.20%和37.50%。The purification effects of NH4^＋-N,TIN and PO4%3--P and growth conditions of A lternanthera philoxeroides（Mart.） Griseb and Carex phctcota Spr. in three types of high salt of river in Zhoushan islands （low, medium and high salinity） were studied experimentally by water culture of monocuhure and mixture. The results indicated that plants grow normally both in Monoculture and Mixture, and grow better in the low and medium salinity river water than that in the high salinity. The high salt of river in island could be purified well by the two kinds of plants, the purification effects of NH4^＋-N ,TIN and PO4^3-P were the best by A.philoxeroides of monocuhure, which were 32.86%, 31.20% and 37.50%.
