摘    要:为了探究影响胡杨(Populus euphratica)回涡沙丘发育的主导树木因子和影响胡杨生长的沙丘因子,以别里库姆沙漠为研究区,采用无人机航拍与影像解译法获取胡杨与胡杨回涡沙丘的形态参数,并结合相关统计分析法从定量角度对胡杨与胡杨回涡沙丘的形态特征间的关系进行分析。结果表明:(1)胡杨回涡沙丘以胡杨为中心,整体形状类似"n"形。胡杨形态参数的大小与胡杨回涡沙丘形态参数的大小基本保持一致。(2)胡杨的形态特征与胡杨回涡沙丘的形态特征具有显著的相关关系,胡杨的生长和胡杨回涡沙丘的发育之间存在协同变化趋势。(3)胡杨株高和冠幅是影响胡杨回涡沙丘的主导树木因子,影响胡杨的主导沙丘因子分别是沙丘表面积、体积、周长、丘体长度。

关 键 词:胡杨  回涡沙丘  形态特征  别里库姆沙漠

Abstract:In order to study the dominant tree factors affecting the development of echo dunes Populus euphratica and the factors of dunes affecting the growth of P. euphratica, taking the Birkum Desert as the research area, and drone aerial photography and image interpretation were used to obtain P. euphratica and itsmorphological parameters, combined with related statistical analysis methods to quantitatively analyze the relationship between the morphological characteristics of P. euphratica and echo dune. The P. euphratica sand dune was centered on P. euphratica, and its shape was similar to the "n" shape. The size of each morphological parameter of P. euphratica was consistent with the echo dune. There was a significant correlation between the morphological characteristics of P. euphratica and its echo dunes. There was a synergistic trend of morphological characteristics between P. euphratica and its echo dunes. Among them, the height and crown width of P. euphratica are the dominant factors affecting echo dunes. The dominant dune factors affecting P. euphratica are the surface area, volume, perimeter and length of dune.
Keywords:Populus euphratica  Echo dunes of Popul useuphratica  Spatial morphological characteristics  Birkum Desert
