摘  要:
以野外地形、土壤实地调查资料为数据源,利用GIS软件建立DEM并进行高程分带和空间叠置分析等,研究了家庭牧场尺度上土壤空间分异与其理化性质相互关系,阐明了该牧场土壤不同海拔高度的肥力状况。结果表明:土壤理化性质的空间分异差异性较大,土壤全氮、全磷、速效氮、速效磷、有机质、细粉粒表现为在海拔最高处含量最高;土壤pH值、盐分与海拔高度没有明显关系。

摘  要:
The spatial distribution and physical and chemical characters of the soil in the household pasture scale were analyzed based on the data from field terrain and investigated soil,using the GIS software to set up DEM to analyze elevation classification and spatial superposition.Its aim was to explain fertility character of soil in the different elevation.The results indicated that the spatial distribution of soil physical and chemical characters varied largely,and the contents of total N,total P,free available N,free available P,organic matter,fine silt in the soil were high at the high elevation,whereas the contents of salt and pH value in the soil were not significant correlation with the elevation.
