| 摘 要： | 梯田地形具有独特的平面和剖面形态特征,而现有梯田地形分类无法准确反映梯田地形的平面形态特征,导致其难以满足未来构建梯田地形数值模拟模型的需求.以黄土高原旱梯田地形为切入点,对梯田地形的总体特征、平面和剖面形态特征及几何量测特征进行深入研究,提出了基于梯田平面形态特征的梯田地形分类,并在结合现有梯田地形分类的基础上,构建出梯田地形综合数字分类.与传统梯田地形分类相比,该分类综合考虑梯田的总体特征和平面及剖面形态,能更好地反映梯田独特的形态特征和几何量测特征.研究结果为未来构建梯田地形数值模拟模型奠定了坚实基础,对于探讨利用DEM实现梯田地形的有效数字表达与分析具有重要理论意义. |

| Abstract: | Terrace is characterized by unique planar and vertical morphology.However,its planar morphologicalcharacteristics can not be depicted accurately by the existing terrace classification,which makes the existing classification difficult to meet the needs of constructing a terrace digital analog model in the future.By taking drought terraceas a key point,the general characteristics,planar and vertical morphological characteristics,and measurablegeometric characteristics of terraces are studied in detail.A new classification of terraces based on the planarmorphological characteristics is put forth.Based on the combination with existing classification,a comprehensive digital classification of terraces is presented.Compared with the traditional classification of terraces,the new comprehensive classification fully considers the general characteristics,planar and vertical morphological characteristics and measurable geometric characteristics of terraces and can better depict the specialmorphological and measurable geometric characteristics of terraces.The results lay a solid foundation for theconstruction of a terrace digital analog model in the future and have important theoretical significance for theeffective digital representation and analysis of terraces by using digital elevation model. |
