摘　　要：以定植两年的四翅滨藜(Atriplex canescens(Pursh)Nutt)土壤为研究对象,测定了总盐量、pH值、有机质、速效氮、速效磷、速效钾与酶活性指标,结果显示,随四翅滨黎种植年限的增加,土壤的总盐量、pH值均有所降低,降幅分别达83.03%和16.82%,有机质、速效氮、速效磷、速效钾与土壤酶活性均有明显增长,增幅分别达38.03%,50.32%,29.05%,14.41%。The soil quality of planted atriplex canescens for two years was studied in this paper,the indexes included the total salt content,pH,organic matter,available nitrogen,available phosphorus,potassium and activity indicators.The results showed that after planting atriplex canescens,with the years of increase,the salinity and pH value decreased in soil by 83.03% and 16.82%,organic matter,available nitrogen,available phosphorus,available potassium and soil enzyme activity had significant growth,increased by 38.03%,50.32%,29.05%,14.41%.
