摘　　要：随着城市绿地与人争水的问题日益突出,再生水作为替代水资源在草坪草上的应用日益广泛。本试验于2003-2005年用3种类型灌溉水(清水、“清水+再生水”、再生水)处理5种草坪草(草地早熟禾、高羊茅、结缕草、野牛草和山麦冬),从观赏品质和生长指标方面进行耐污性评价,并分析再生水对土壤的影响。结果表明:本研究使用的再生水对所供测试绿化草种的颜色、覆盖度、质地和均匀性无不良影响,再生水灌溉条件下,高羊茅表现出了最强的综合耐污能力,其次是结缕草和野牛草。灌溉水类型对于草坪草的生长指标的影响具有种的特异性。再生水灌溉和“清水+再生水”交替灌溉提高了土壤的阳离子交换量(CEC)和总孔隙度,有利于土壤物理性状的改善。As the shortage of water resource is seriously, reclaimed water has been used on turf as substitute of fresh water. 3 types of water （fresh water, fresh ＋ reclaimed water, and reclaimed water）were used to irrigate 5 common turfgrasses （ Poa pratensis , Festuca arundinacea , Zoysia japonica, Buchloe dactyloides , Radix liriopes ） during 2003-2005; the growth characters and sensory quality of turf grasses and soil responses were investigated. The research result showed that （ 1 ） The reclaimed water used didn＇ t influence the sensory quality of a given turf grass tested; under irrigation of reclaimed water , Festuca arundinacea are the best, followed by Buchloe dactyloides and Zoysia japonica; （2） The influence of different types of irrigation water on growth characters of turfgrass is speciesdependence; （3） Irrigation by reclaimed water and fresh ＋ reclaimed water increases Na^＋ , CEC, and total porosity of the tuff soil in comparison to fresh water, and improves soil quality.
