• 【Objective 】 The vegetation and shape characteristics and spatial distribution of Nitraria tangutorum Nebkhas in different developmental stages were studied to characterize the spatial point distribution and patterns of variation of N.tangutorum Nebkhas with the increase of size of the sandpiles in order to reveal the characteristics of community formation and the mechanism of maintaining ecological patterns of N.tangutorum Nebkhas during the development process. 【Methods】Based on field investigation,four typical sample plots of N.tangutorum Nebkhas in 4 different developmental stages,i.e,prototype,developing,stabilizing,and activating,in Minqin desert-oasis ecotone were selected.In light of the two-dimensional coordinates,the N.tangutorum Nebkhas were graded into 3 classes,i.e.small,medium and large,respectively,according to the volumes of sandpiles.Their spatial distribution were analyzed with the univariate O-ring function while the correlation among different grades of the sandpiles at different scales wa
