中文摘要	通过对策勒河下游砾质戈壁典型的沙拐枣植株及灌丛沙堆形态参数进行野外测量,用数理统计方法进行相关性分析。结果表明:沙拐枣植株冠幅南北宽度与沙堆宽度呈明显正相关性,植株冠幅东西宽度与沙堆长度不呈现明显相关性。植株冠幅面积与沙堆底面积呈现明显线性相关性,确定系数0.81,冠幅面积与沙堆体积呈现良好线性相关性,确定系数0.69,沙堆长度与沙堆宽度、沙堆高度与沙堆底面积之间呈现一定程度相关性。株高、冠幅东西宽度、南北宽度与沙堆迎风坡和背风坡长度、总长度、沙堆宽度、沙堆高度两两之间都呈现出极显著相关性。沙堆迎风坡坡度与沙堆高度、背风坡坡度之间呈现极显著相关外,与其余形态参数都没有显著相关性。沙堆背风坡坡度除了与株高、背风坡长度、沙堆总长度无明显相关外,与其余形态相关参数都表现为极显著相关性。
英文摘要	Through field measurement for the morphological parameters of typical Calligonum plants and Calligonum nebkhas on gravel Gobi desert in the downstream Cele River,the relativity between them were analyzed by method of mathematical statistics.The outcomes indicated that there was significant positive correlation between plant width in north-south direction of crown diameter and nebkhas width of Calligonum ,the correlations between plant width for east-west direction of crown diameter and nebkhas width was not obvious.There was significant linear correlation between crown area of plants and base area of nebkhas,and the square of determination coefficient were 0.81.There was well correlation between crown area of plants and nebkhas volumes,and the square of determination coefficient was 0.69.There existed certain correlation between length and width of nebkhas and height and base area of nebkhas.There were significant correlations between height,crown width in north-south direction and east-west direction of plants and width,height and base area of nebkhas.There were no significant correlated except that of significant correlative correlation between windward slope and nebkhas height and leeward slope of nebkhas.There were significant correlations between leeward slope and other relative parameters except for plants height and length of leeward side and total length of nebkhas.
