京西山地土壤理化性质的分布

采用ＦＯＸＰＲＯ数据库和Ｃ语言编制成《土壤理化性质分析与图形制作》通用计算机软件，可对调查数据进行分析处理，直观地输出土壤理化性质随土壤深度的分布图和数据文本．应用该软件，对京西山地不同海拔高度、不同土壤种类试验地的土壤质地、土壤容重、比重和孔隙度以及有机质含量、阳离子交换量、盐基饱和度、ｐＨ值、全氮量、速效磷、速效钾等理化性质随土壤深度的分布规律进行了分析研究

Analysis of Soil Physi-Chemical Properties of Beijing Xishan Mountain

A program of the module of the soil physical and chemical properties has been made on the basis of C language and Foxpro. The investigation data can be processed by using the software, what's more, a distribution map of the soil physical and chemical properties change with the soil depth as well as the data text can be produced directly. In this article, soil texture, soil bulk density, soil specific gravity and soil porosity in different experimental sites and different elevation and organic matter content, cation exchange capacity, degree of base saturation, pH value, N, P and K distribution with the soil depth are researched on the basis of the software.
