    基于DEM的广东省赤红壤全氮含量与地形特征相关分析

    The Correlation Analysis on the Soil Total Nitrogen Content of Lateritic Red Soil and Terrain Characteristics in Guangdong Province Based on DEM

    • 摘要: 以土壤类型图、地形图、全氮图等资料为数据源,利用ArcGIS 9.2建立广东省赤红壤数字高程模型(DEM),提取海拔高度、坡度、坡向和地势起伏度,探索大尺度下全氮分布与地形特征的关系.研究表明:全氮含量与海拔高度、坡度和地势起伏度呈负相关关系,并随着海拔高度、坡度和地势起伏度的上升分布面积迅速下降,在坡向上,则主要分布于平坦区域和东南坡.
