摘　　要：通过对宁夏南部半干旱退化山区不同土地利用方式土壤物理性质的定位监测,结果表明:半干旱退化山区采取不同土地利用方式,改善了土壤结构和肥力,增加了土壤的通透性,改变了土壤水肥气热状况。但不同措施对土壤理化性质的改善具有一定的差异性,"88542"水平沟整地(林地)对土壤的改良效果最好。Characteristic on soil physical properties of different land use patterns in semiarid degraded mountain area were located monitored. Result shows that： different land use patterns were adopted in semiarid degraded mountain area; soil structure ＆ fertilizer were improved, permeability of soil were increased, condition of water, fertilizer, air and heat of soil were changed. But different measures have certain differences on the improvement of soil physical properties ; ＂88542＂ horizontal ditch（forest land）have the best improvement effect on soil.
