摘要:为了更好地了解晋西不同土地利用方式下的土壤水分特性,利用土壤水分渗透仪测定饱和导水率(Ks),室内测定土壤物理化学性质,分析了饱和导水率与各项土壤物理化学性质指标的相关关系。研究结果表明,土壤饱和导水率随土层深度增加而下降;土壤饱和导水率表现为:林地>地埂>农地;土壤饱和导水率与容重、非毛管孔隙度、>0.25mm水稳性团聚体、土壤有机质含量等土壤理化特性存在显著相关关系。晋西地区应合理配置林地、地埂、农地,减少荒地,改善土壤的通气透水特性,改良土壤结构。
In order to better understand the characteristics of soil water under different land use modes, the physical and chemical properties of the soil was analyzed with the saturated hydraulic conductivity(Ks) tested in laboratory by soil water lysimeter and the correlations between the soil saturated hydraulic conductivity and its physical and chemical properties was achieved. The saturated hydraulic conductivity of the soil was decreased with soil depth while the Ks was in the decreasing order in the forestland, field ridge and farmland. The K, had the significant correlationship with the soil bulk density, non-capillary porosity and water-stable aggregates (〉0.25 mm) and organic content. It is suggested that the forestland, filed ridge, farmland should be deployed rationally with the reduction of the abandoned land to improve the permeability and texture of the soil.
