山顶点类型及其形态特征数字表达

山顶点是最重要的地形特征点.本文在首先分析了山顶点所具有的空间特征、成因特征、尺度特征及点群特征的基础上,依照科学性、系统性、实用性、可实现性的原则,对山顶点进行了系统的分类,并阐述了其定量描述方法.此外,深入探讨了山顶点群的基本类型、定量描述指标与地学意义.该研究对于构建以山顶点为主体的地形特征点簇,以及进行基于地形特征点簇的地貌模式识别,都具有十分重要的意义.

Classification of Peaks and Digital Expression of Their Spatial Pattern

Peak is the most significant point of the relief surface.On the basis of peak's spatial characteristic,formative characteristic,scale characteristic and clustery characteristic,a systematic classification of peaks is carried out and their quantitative description is brought out on a series of principles.Moreover,the general types of peak cluster,its quantitative description standards and geographic significances etc.are clarified.This research should be helpful to perfect the methodology of DEM based digita...
