摘　　要：选用灌木、草坪草、灌草结合3种植被配置方式进行盆栽试验,以无植物盆栽作为对照,研究了植被配置条件下土壤总磷的动态变化。结果表明,有植被配置处理的土壤残留总磷含量总体上都小于对照处理,差异均达到了显著水平;对于磷素的吸收,草坪草处理效果好于灌木,草坪草能更有效地吸收土壤磷素;灌木和草的交互作用显著。数据分析表明,对土壤总磷的削减效应依次为灌草结合>草坪草>灌木>对照,因此对磷的削减效应最佳的植被配置方式为灌草结合。The pot experiment of different vegetation configuration（frutex,lawn and shrub-grass） was conducted in comparison with control group（non-plant）（CK）,on this condition,the dynamic of soil total phosphorus was studied.The result shows that：①The difference between experimental group and control group was visible on total phosphorus,and the experimental group was significantly lower than control group.②The sorb effect on total phosphorus of lawn was better than that of frutex.③Statistics data indicate that the interaction of frutex and grass was evident,and as far as the decrease effect on phosphorus,the configuration of shrub-grass was the best.
