摘要/Abstract

摘要： 以焉耆盆地的白刺纯林、白刺红柳混合区和白刺胡杨混合区的灌丛沙堆为研究区域，分析不同生境白刺灌丛沙堆的长、宽、高、面积、体积、株高等方面的形态特征和形态参数间的相关性。结果表明：（1）不同生境白刺灌丛沙堆形态参数分别为长度1.2~10.7 m、宽度1.2~6.3 m、高度0.5~2.4 m、面积1.2~50.1 m²、体积0.7~80.3 m³、株高0.6~1.6 m；（2）白刺沙堆各形态参数间具有极强的相关性，其中不同生境3个样地上的白刺沙堆长度与宽度间、沙堆面积与高度、沙堆体积与面积间都表现为极显著相关。以不同生境白刺灌丛沙堆形态参数间的相关性分析结果为基础，分别对不同生境白刺灌丛沙堆长度与宽度、高度与面积、面积与体积间进行回归方程拟合，结果显示：除了白刺胡杨混合区沙堆高度与面积的拟合方程R²为0.3853较低以外，其余白刺沙堆各形态参数间的拟合方程R²均在0.7538~0.9895之间，说明沙堆的各形态参数间的关系非常密切。研究结果对提出防风固沙的生物措施具有非常重要的科学意义。

Abstract: The Nitraria forest, Nitraria Tamarix ramosissima mixed forest and Nitraria Populus diversifolia mixed forest nebkhas in Yanqi Basin were used as research area, the correlations between morphological characteristics (such as length, width, height, area, volume, plant height) and morphological parameters of Nitraria nebkhas under different habitats were studied. The results showed that: (1) the morphological parameters of Nitraria nebkhas under different habitats were length 1.2-10.7 m, width 1.2-6.3 m, height 0.5-2.4 m, area 1.2-50.1 m², volume 0.7-80.3 m³, plant height 0.6-1.6 m; (2) the correlations among morphological parameters were strong, length and width, area and height, volume and area were significantly correlated under three habitats. Based on the results of the correlation analysis of morphological parameters, regression equations of nebkhas length and width, height and area, area and volume were fitted, the results showed that: R² of height and area was between 0.7538 and 0.9895, except that of Nitraria Populus diversifolia mixed forest which was 0.3853, indicating that different morphological parameters were related closely. This study had certain significances on biological measures in wind prevention and sand fixation.
