摘　　要：选择宁南半干旱退化山区彭阳中庄小流域为典型示范区，采用生态工程技术对各种退化生态系统恢复与重建模式进行了试验研究。结果表明，通过实施水土保持工程治理措施和生物措施相结合法对小流域的综合治理，在0～100cm土层，不同生态恢复与重建地土壤理化性质包括土壤机械成分、团聚体、容重、水分、持水量和肥力状况等有了一定程度的改善。这就要求在以后的生态恢复与重建中，要深入了解当地的环境特征，做到因地制宜，适地适树，合理规划和利用土地。Choosing the typical model district of small watershed of Pengyang Zhongzhuang in semi-arid degeneration mountainous area of Southern Ningxia, the experimental study on each kind of degeneration ecosystem is conducted with the reconstruction pattern by the ecological engineering technology. The results showed, through implying conservation of water and soil project government measure and the biological measure to administer comprehensively the small watershed, in the 0-100 era soil layer, the different ecology restoration with the reconstruction land soil physical land chemical properties including the soil mechanical component, reuriites the body, soil bulk, the moisture content, the soil capacity and the fertility condition and so on had the certain degree improvement, This request us in the later ecology restoration with the reconstruction, it is a must to thoroughly understand local environment eharacteristic, choose suitable tree, plan and use land reasonable.
