  • 摘要: 以西藏雅鲁藏布江流域沙化土壤为研究对象，采用拉萨污水处理厂脱水污泥进行添加处理，测定了不同污泥掺混量下土壤基本理化性质变化趋势，并与当地农田、草地生态系统土壤进行了比较。结果表明：随着污泥掺混量的增加，沙化土壤的孔隙度逐渐提升（P<0.001），土壤密度及容重逐渐降低，在掺混量大于10%时，改良效果趋于减缓；土壤氮、磷、有机质含量呈增加趋势，在掺混量为10%~15%时与对照土壤氮、磷含量相近，在掺混量为20%~30%时，有机质含量与对照相近；土壤最大持水量呈增加趋势，在掺混量为5%~10%时即与对照土壤相近；拉萨污水处理厂污泥重金属含量远低于国家农田土壤标准，且含有一定的植物生长必需元素，是一种理想的沙化土壤改良剂。
    Abstract: The rational disposal of urban sludge is of great significance to the ecological environment protection in the Tibet plateau. In this study, sandy soils in the Brahmaputrain Tibet were selected and the different amounts of dewatering sludge in Lhasa sewage treatment plant were added,then soil physical and chemical properties were determined to confirm the change tendency of under different sludge mixing rates, and soils in local farmland and grassland were selected as control. Results showed that the porosity of desertified soil was gradually increased (P<0.001) and the density of soil particles and soil bulk density were decreased (P<0.001)gradually with the increase of sludge percentage. When the adding amount was more than 10%, the improvement effect tended to slow down. Soil nitrogen, phosphorus and organic matter showed an increasing trend. The contents of nitrogen and phosphorus in improved soil were closed to the comparative soil when the sludge amount was between 10% and15%. When the sludge amount was between 20% and 30%, the organic matter content was closed to the control. Maximum water holding capacity in improved soil showed an increasing trend,which was close to the control soil when the mixing amount was among 5% and 10%.At the same time, this study also shows that the content of heavy metals in Lhasa sludge is much lower than the national farmland soil standards, and contains certain essential elements for plant growth, which is an ideal soil amendment for desertification.
