摘　　要：为了筛选出护坡效果良好,且具有较好生态效益的河道植被,在模拟农村驳岸上种植马蹄金、美人蕉、杞柳3种植被,对其坡面界面伴生植物、节肢动物、土壤微生物的种群多样性和稳定性等进行生态效应研究。结果表明:除秋季伴生植物外,春秋2季3种植物的生物量,伴生植物和节肢动物的Shannon-Weiner指数和均匀度指数均为:马蹄金<美人蕉<杞柳;Simpson多样性指数:马蹄金>美人蕉>杞柳。且杞柳土壤微生物的细菌总数最多,达到7.7×108cfu/g土,硝化菌和反硝化菌达到3.2×106cfu/g土以上。秋季马蹄金被加拿大一枝黄花等伴生植物所取代。可见,杞柳驳岸是生态效应最佳的植被驳岸,其次是美人蕉驳岸,而马蹄金驳岸不适合作植被驳岸。In order to select out the effective riverbanks vegetation,ecological effect analysis of diversity and stability which of accompanying plants,arthropoda,soil microbe had been studied on the three vegetation riverbanks,where Dichonda repens,Canna indica and Salix integra were planted.The results showed that,despite of accompanying plants in autumn,biomass of plants,Shannon-Weiner index and evenness index of accompanying plants and arthropoda of 3 vegetation riverbanks were Dichonda repens Canna indica Salix integra;Simpson index was Dichonda repens Canna indica Salix integra.Bacteria amount in Salix integra soil was most,which was 7.7×10 8 cfu/g soil,nitrifier and denitrifying bacterium were more than 3.2×10 6 cfu/g soil.In autumn,Solidgo canadensis and other accompanying plants replaced Dichonda repens.At all,Salix integra riverbank was the best vegetation riverbank according to ecological effect,following with Canna indica and Dichonda repens was unsuitable for riverbank vegetation.
