| 摘 要： | 通过对黄河小浪底库区不同恢复阶段土壤的调查研究,结果表明,库区土壤大部分出现中度退化,很少一部分退化为弱退化,一部分为强度退化.乔木恢复阶段中次生栓皮栎林地土壤退化最轻;库区土壤退化类型有贫养分化、贫微生物化、结构劣化、碱化和严重干旱化.3个恢复阶段的土壤退化程度为,乔木恢复阶段＜灌丛恢复阶段＜草本恢复阶段,其中,人工侧柏林下土壤退化程度较灌丛和魁蒿的重些.

| Abstract: | Investigation on soil degradation in different restoration stages in Xiaolangdi reservoir area of Yellow River showed that the soil in reservoir area appeared mid degradation mostly,a part of it was intensely degraded and a few was light degraded.The soil degradation degree in the woodland of Quercus variabilis was lightest in arbor restoration stage.The main types of soil degradation were of poor nutrients,poor microorganism,bad structure,basification and heavy drought.The order of soil degradation degree for three different restoration stages was arbor restoration stage
