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。
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.
