绿废有机基质对城市绿地土壤养分含量的影响

Effect of Green Waste Organic Matrix on the Soil Nutrient Content of Urban Greenbelt

在山西省太原市选择3处具有典型特征的绿地,采取4种不同的处理方式,研究了绿废有机基质对城市绿地土壤养分含量的影响。结果表明,对于人为污染较重或养护管理水平较差的绿地土壤,宜采用搅拌覆盖绿废有机基质的方式,以起到最佳的土壤改良效果;对于正常养护管理条件下的绿地,采用填埋覆盖绿废有机基质的方式可最大限度提升土壤质量。

3 typical green spaces were selected in Taiyuan City of Shanxi Province,and 4 different treatment methods were adopted to study the effect of green waste organic matrix on the soil nutrient content of urban greenbelt.The results indicated that for the greenbelt which soils heavily polluted by human activities or the soil with poor maintenance and management level,it was advisable to use mixing and covering with green waste organic matrix to achieve the best soil improvement effect.For greenbelt under normal maintenance and management conditions,using landfill to cover green waste organic matrix could maximize soil quality.
