32 ，分布在起伏度指数7上的土地所占比重最大，占14 54 。全研究区地形分布表现出低、中、高三段式空间分布结构。 - Applying the basic theories of spatial data mining and geomorphology , taking the loess plateau of north shaanxi province , china as the research area , this dissertation explored the theories and systematic structures of geomorphologic data mining and acknowledge discovery from dems , ascertained the systematic structures of topographic factors and synthetic topographic acknowledge , as well as systemically summarized mining algorithms from dems . the author pa id more attention also to analyze the principle and algorithm of flow length , curvature , relief , the earth ' s surface incision and gully density . in this research , the elementary constitutes and mining algorithms of regional character acknowledge in the loess plateau were probed
本研究在广泛总结前人研究成果与研究经验的基础上，利用空间数据挖掘和地形地貌学的基本理论，以陕北黄土高原多地貌类型区为实验样区，以1 10000比例尺dem为样本数据，探讨了dem中地形地貌数据挖掘与知识发现的理论方法和体系结构；确定了宏观和微观地形因子、地形综合特征知识的体系结构；系统总结了dem基本地形因子的提取算法，并重点对坡长、曲率、地形的起伏度、切割深度和沟壑密度因子提取的原理与算法作了深入的分析；提出了黄土高原地区区域特征知识的基本构成及其系统完整、科学可行的挖掘提取算法；扩充了arcviewgis软件平台中dem空间分析的基本功能；实现了以delphi7 . 0为平台的地形信息辅助挖掘系统的设计与开发；完成了对黄土高原多地貌类型区(样区)地形信息空间分异特征的分析。 - The unconformability between the loess landform of shaanbei loess plateau and its bedrock shape was pointed out first after the full demonstration . the top of loess formation of the south part in shaanbei is flat which likes " platform " , the shape of the bedrock is rolling that likes ridge , and the bedrock bended to fold . the top of loess formation of the mid - part in shaanbei is rolling , but the shape of the bedrock below begins to get flat , the top of loess formation of the north part in shaanbei , loess mao district , is much more rolling among them , however , its shape of the bedrock below is the flattest relatively likes the platform shape of loess formation in south
具体地讲，陕北高原南部的洛） 11黄土源，黄上层顶部相对平坦，地貌类型以黄土源为主格调，而其下伏基岩地层诏皱相对发育，古地势起伏相对较大：陕北高原中部的延安一安塞黄土梁状（为主）丘陵沟壑区，黄土层顶部起伏相对增大，地貌类型以黄土梁为主格调，而其下伏基岩地层槽皱程度趋弱，地层较平缓，古地势起伏相对降低；陕北高原北部的绥德一子洲黄土赤状（为主）丘陵沟壑区，黄土层顶部起伏度相对最大，地貌类型以黄上赤为主格调，而其下伏基底地层以平缓为特征，古地势起伏强度亦相对较低。
