摘　　要：对不同建植年限的多年生草坪土壤进行了物理性状的研究,结果表明,降雨时多年生草坪土壤的水分主要容纳在0～10cm层土壤中;多年生草坪土壤0～10cm层的孔隙度明显大于10～30cm层土壤,并且随着草坪建植时间的增加,0～10cm层的土壤孔隙度有逐渐下降的趋势;多年生草坪0～10cm层的土壤硬度比10～30cm层的大;建植多年生草坪时土壤应采用壤土为宜。The soil physical properties of perennial turf at different age were studied and the results showed that the soil water was mainly held in 0～10 cm horizon when rainfall; the porosity of 0～10 cm horizon was greater than 0～30 cm.At the same time, the soil porosity of 0～10 cm decreased gradually along with the age of turf.The soil hardness of 0～10 cm horizon was greater than 10～30 cm. The loam soil was the best for turf establishment.
