摘　　要：通过测定黄土高原广泛分布且具有代表性的黄绵土、黑垆土及Lou土的颗粒组成、结构性、孔性、物理机械性等土壤物理性质，研究了黄土高原呈地带性分布的3种土壤其物理特性之间存在的差异及呈现的规律性。同时，还着重分析了重壤带的Lou土在不同肥力水平下其物理性质的变化规律。这些研究进一步丰富了对这些土壤相关知识的认识，并为农业生产中合理利用土地提供了基本依据。This research measured particle composition,structural property,poral property and physical mechanical property of loessal soil,Heilu soil and Lou soil which distributed extensively and representatively in loess plateau.The discrepancy and regularity of the three zonal soil physical properties were studied.In the mean time,we also analysed changing laws of Lou soils physical properties in heavy loam soil region under different fertility level.The content of these research enriched relative knowledge of these soils furtherly and provided basic foundations for utilized land rationally during agricultural production.
