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
本研究在廣泛總結前人研究成果與研究經驗的基礎上，利用空間數據挖掘和地形地貌學的基本理論，以陜北黃土高原多地貌類型區為實驗樣區，以1 10000比例尺dem為樣本數據，探討了dem中地形地貌數據挖掘與知識發現的理論方法和體系結構；確定了宏觀和微觀地形因子、地形綜合特徵知識的體系結構；系統總結了dem基本地形因子的提取演算法，並重點對坡長、曲率、地形的起伏度、切割深度和溝壑密度因子提取的原理與演算法作了深入的分析；提出了黃土高原地區區域特徵知識的基本構成及其系統完整、科學可行的挖掘提取演算法；擴充了arcviewgis軟體平臺中dem空間分析的基本功能；實現了以delphi7 . 0為平臺的地形信息輔助挖掘系統的設計與開發；完成了對黃土高原多地貌類型區（樣區）地形信息空間分異特徵的分析。 -
According to many aspects, such as topography and geomorphology, types and distribution of soils or rocks, geotechnical composition pattern and the features of each geomorphic unit zone, geotechnical properties and so on, zhengzhou urban zone is classified into four geotechnical engineering zones. that ' s hilly country whose disrupted ground surface has damp and caving loess, vitruvian plain country whose vitruvian field of ground surface is easy to be leveled, oblique plain country which has leveler topography and good bearing layer, and overflowing plain features and differences of geotechnical engineering properties of foundation soil, each geotechnical engineering zone is also classified into different sub - zones of geotechnical engineering. and evaluation is given to geotechnical engineering condition, the suitable ability to buildings and the scheme of foundation in each zone
各巖土工程區又根據其微地貌特徵及表層土工程地質性質的差異分為不同的巖土工程亞區（即區分為表層具濕陷性的巖土工程亞區（ _ 1區）和表層不具濕陷性的巖土工程亞區（ _ 2區） ；區分為局部易發生濕陷的巖土工程亞區（ _ 1 ）和不具濕陷性的巖土工程亞區（ _ 2 ） ；區分為上部有厚層填土的巖土工程亞區（ _ 1 ）和上部有軟土分佈且有過大的沉降的巖土工程亞區（ _ 2 ） 。
