摘　　要：使用椰壳植物纤维改良受建筑废弃物混凝土、水泥、石灰渣石污染的城市绿化土壤 ,试验表明 :用椰壳植物纤维和土壤重量比在 1∶10～ 15 ,可以显著改善被污染土壤理化性能 ,减少容重 ,缓解土壤板结状况 ,提高土壤保水能力和水的利用率 ,节约浇灌用水 ;增加土壤微生物种类和数量 ,使土壤较适合城市绿化植物的生长。The experiment showed that with the ratio of the coir fibre weight to the soil weight,1∶10～15,the polluted soil physics and chemistry performance might be improved evidently,bulk density was reduced,the soil surface crusting condition was alleviated the soil water retaining capacity and water utilization percent were raised,and water used for pouring was saved;the soil microbe kind and quality were increased in order to make the soil adapt to the urban green plant growth relatively.
