摘  要：
为了探讨植被恢复对土壤养分的影响,研究了科尔沁沙地南缘沙化土地治理区有林地的土壤养分特征。结果表明:治理区有林地与未治理沙化土地土壤有机质、全氮、有效氮、速效磷存在明显差异,在土壤养分改善过程中,呈现有机质、全氮、速效氮、全磷和速效钾养分指标同步上升的规律,表明人工的治理措施以及植被对土壤的改良作用较强;有林地与对照样地PH值差异相对较小,表明人工的治理措施以及植被对土壤的改良作用在土壤的酸碱性上较弱。

摘  要：
In order to explore the influence of vegetation restoration on soil nutrients,the soil nutrient characteristics of the forest land in the restoration area in the south of Horqin desertificated land were studied. The results showed that the soil of forestland in the restoration area and that in the desertificated land had significant differences in the soil organic matter, total nitrogen, effective nitrogen, and rapidly available phosphorus. In the process of soil nutrient improvement all these nutrient indexes have synchronous rise, which indicated greater effects of artificial control measures and vegetation on the amelioration of soil; The difference of p H value between the forest land and contrastive plots was relatively small, which indicated the artificial control measures and the improvement of vegetation on soil are weak in acidity-alkalinity of Soil.
