摘　　要：陇东黄土高原沟壑区地形地貌复杂,小城镇空间分布受到极大影响。通过实地调研与GIS技术相结合的方式,对小城镇空间分布的地域特征及其形态特征进行系统分析。结果显示:该地区小城镇主要分布在海拔1100~1400m、坡度0°~5°的区域,即较完整塬面或河川川道区域;城镇空间分布趋水性及交通指向性特征明显;城镇多分布在中南部塬区及沟壑区,西北部及东部丘陵区城镇分布较少,呈南密北疏趋势;结合地形地貌,提出台塬型、川道型、山地型等三种城镇空间形态。针对小城镇空间分布特征,提出该地区各小城镇形成"小城镇群",分工协作、相互促进发展,并提出自然、社会、经济适应小城镇生态基质导向下的城镇空间有机生长的地域适应性发展模式的设想。Complex terrain and landform influence the spatial distribution of small towns in the Longdong Gully Region of Loess Plateau. We analyze the regional characteristics and morphological characteristics of the spatial distribution of small towns, with the field investigation and the technology of GIS. The result shows as follows： small towns are mainly distributed in an altitude of 1100~1400m, slope of 0 °~ 5 °, the area is the relatively complete loess tableland or the valley and plain regions. River directivity and traffic directivity are main spatial characteristics of the small towns. Most of the small towns distribution in the south, the northern area is less. Based on the terrain and physiognomy, we put forward three kinds of urban spatial form, which is flatland type, corridor valley type, and valley type. Aimed at the spatial distribution characteristics, we put forward ideas about the group of small towns and the regional adaptability of space development pattern.
