| 摘 要： | 土壤资源是人类生存和可持续发展的基础。土壤空间分布规律的分析一直是土壤学研究的重要课题。研究应用GIS的复合叠置分析、聚类聚合分析、统计学分析等方法,探索了中尺度土壤分布规律及土壤理化性质随海拔高度、坡向变化而变化的规律。研究发现:地理信息科学方法和技术应用于土壤学研究是可行的,有传统分析方法所无法比拟的优越性;西安市土壤有明显的空间分布规律(垂直地带性明显,随地形因子变化土壤理化性质发生相应变化)。

| Abstract: | Soil resource is the basis for human existence and sustainable development.The analysis of soil spatial distribution pattern is constantly an important research aspect in soil science.GIS spatial analysis methods,such as overlay,complex and cluster,and statistical analysis method were employed to the research on middle-scale soil distribution pattern and soil physical and chemical properties varying pattern.Experiments show all these factors have a close relationship with the elevation and aspect.The results of this research show that the applica- tion of GIS method to soil science research is feasible.Xi'an area's soil possesses distinct spatial distribution pat- tern,for instance,soil distribution possesses obvious vertical zonization,soil physical and chemical properties have an obvious related variation With the terrain factors. |
