摘　　要：对科尔沁沙地西南部种植时间为2000年、2004年及2007年的不同林龄黄柳灌丛0~60cm土壤9项指标进行测定。结果表明：3种林龄黄柳灌丛各土层土壤全磷、全钾含量均表现为10a生含量最高,7a生次之,14a生最低;土壤p H表现为随林龄增加而降低;3种黄柳灌丛0~60cm土层全氮、速效钾、土壤有机质、土壤p H表现为随林龄增加而降低;全磷、全钾、速效磷及水分表现为10a生最高,7a生次之,14a生最低;碱解氮表现为7a生〉14a生〉10a生;土壤有机质与全氮达到了0.87的高度正相关。Determination of 9 soil index in the soil layer（0 -60cm）of Salix planted in 2000,2004 and 2007 was done in southwestern Horqin sandy land. The results showed that total P and K in each soil layer of the 3 Salix shrubs of 10 years old 〉 7 years old 〉 14 years old, the pH 7 years 〉 10 years 〉 14 years. 7 years 〉 10 years 〉 14 years in soil layer（0 ~ 60era）of the 3 Salix total N. available K, soil organic mat- ter and pH. Total P,K available P and H20 is 10 years 〉7 years 〉 14 years. Available N is 7 years 〉 14 years 〉 10 years. Correlation analysis showed that there was a positive correlation between soil organic matter and total N that was 0. 87.
