摘要

通过对青海省沙珠玉治沙站人工植被恢复不同土壤发育阶段土壤理化性状的研究

结果表明

人工植被恢复对荒漠化土壤具有很好的改善作用

随着流动沙丘被固定

机械组成中砂粒逐渐降低

粘粒和粉粒含量逐渐提高

土壤有机质和养分含量及CEC逐渐提高

土壤pH值变化不大

碳酸钙只是在表层升高。已经发生荒漠化的地区恢复到正常土壤需要的时间相当长

因此人们应减少人为因素对荒漠化的影响。

Abstract

In this study

soil physical and chemical characteristics in different develop stage after artificial vegetation restoration have been researched in Shazhuyu desert control site.The result showed that artificial vegetation restoration have better impact to sandificational soil.With the sand dunes have been fixed

the content of sands reduced gradually

but silt and clay rose;soil organic matter

nutrient and CEC gradually rose;soil pH value had no larger change;calcium carbonate content only rose on top layer.It need a long time for sandificational land evolve into natural soil

so people should deduce artificial influence to sandificational land.
