【摘要】 以遥感图像为基本信息源,对黄土高原沟间地地貌信息图谱的基本单元墚、峁进行提取与分析,主要内容包括图像预处理、图像识别、模式图操作、数据库管理和属性库管理5个部分。通过提取地物个体单元的边界得到每种图谱类型的标准参数和模式图,对未知类型的图谱个体单元提取参数后与模式图比较分析,归为相应类型的数据库中。最后对下一步的工作进行了展望。更多还原

【Abstract】 The basic components of the inner-gully land in Loess-Plateau-Information-Geomorphic TUPU is Loess-mao and Loess-liang,which was extracted and analyzed based on the remote sensing image.The main contents are consist of five parts,including pre-disposal of image、image recognization、model-graph operation、database management and attribute-database management.Standard parameters and model-graph of each kind of Geo-info TUPU was built through extracting the boundary of each geomorphic unit,then the unknown kind of geomorphic unit can be classified into the corresponding databases by comparing with the model-graph after the extraction of the parameters.At last the next procedures are put forward.更多还原
