| 摘 要： | 为全面了解不同植被建设措施对沙化土地理化性质的影响,在黄羊滩地区选取不同树种、不同配置结构中具有代表性的植被建设措施,按随机抽样布点,分层取土样。制成混合土样后测定其各项理化性质数据,并对不同治理措施内的沙地土壤理化性质进行对比分析。结果表明:纯林地土壤肥力以小叶锦鸡儿最佳;乔灌混交林改良土壤的效果好于乔木纯林。该成果为采用植被建设措施改良沙化土地提供了科学依据。

| Abstract: | In order to know the effect of different vegetation resume measure on soil physicochemical properties of desertification land,representational vegetation resume measures were chosen such as different plant condition,different mixed forest in Huang Yangtan.Random sample,soil physicochemical properties of different vegetation resume measure were compared .Indicate that Caragana microphylla of artificial vegetable condition is the best measure to resume the soil nutrient,mixed forest is better than pure forest.And the direction was provided for the vegetation resume measure . |
