中文摘要	为了探讨小尺度风沙地貌形态的空间变异过程,对塔克拉玛干沙漠腹地高大复杂纵向沙垄横断面上简单横向沙丘形态特征进行了研究.沙丘形态野外测量采用RTK(real-time kinematic)技术,并通过南方测绘软件(south survey)量算形态特征参数.结果表明:简单横向沙丘形态特征参数及其相互关系具有空间变异性.在8个地貌部位之间,沙丘形态特征参数(不包括迎风坡度)存在显著性差异,主要体现在:垄顶、沙垄背风坡、其他地貌部位(包括垄间地和沙垄迎风坡)三者之间的差异.地貌部位、输沙风强度以及沙丘活动强度是驱动沙丘形态空间变异的因素.沙丘高度与翼展度余弦有负对数关系,发育指数与高度、迎风坡度成负线性相关,这些相关性的显著程度在垄顶、背风坡较高,在垄间和迎风坡较低.
英文摘要	In order to explore the morphologic features of small-scale aeolian-sand landforms and their spatial variation , in this paper, the morphologic features of the simple transverse dunes over the cross-section of the tall-complex sand ridges in the hinterland of the Taklimakan Desert are researched. The real-time kinematic technology was used to measure the morphometric parameters of the simple transverse dunes in field, and the software South Survey was used to calculate the main parameters. The result shows that there are the spatial variations in the morphometric parameters of the simple transverse dunes and their interrelations. There are the significant differences between the morphometric parameters measured at 8 different geomorphologic sites ( excluding those measured at the windward slope) , especially between those measured at the ridge top, leeward slope of the ridge and other morphologic sites (including the inter-ridge lowland and windward slope of ridge). Geomorphologic sites, intensity of sand blown by wind and movement intensity of dunes are the driving factors of spatial variation of the morphometric parameters of the simple transverse dunes. There is a negative logarithmic relation between height and cosine of the dune wing-span, and there are also the negative linear relations between the development index and the height and windward slope of ridge. However, the significant extents of these correlations are high for the ridge top and the leeward slope of ridge but low for the inter-ridge lowland and the windward slope of ridge.
