纵穿古尔班通古特沙漠中部对风沙土理化性状分析结果表明:沙漠腹地风沙土含水量低于边部。风沙土颗粒物主要由极细沙-细沙-中沙组成,并且北部较中部和南部粗。个体沙垄垄间地风沙土φ1值最高,垄顶的平均粒径最大。北部风沙土分选性差,绝大多数为极正偏分布,峰态很窄。中部、南部风沙土分选性中等和较好,呈窄峰态和近对称的分布形式。沙漠腹地风沙土全盐含量均较低,pH值适中,二者和沙垄固定程度成一定的正相关。风沙土中有机质、N、P、K等营养物质含量较低。相比之下北部风沙土全K和有机质含量高于中、南部,而植被茂盛的垄间地和垄坡有机质和全N含量一般高于固定、半固定垄顶。局地气象条件、微地形地貌以及植被状况的差异是引起沙漠风沙土上述理化性状空间分异的重要因素。 Through the analysis of physical and chemical properties of wind-blown soil in central Gurbantunggut desert, the results show that the moisture content of wind-blown soil in desert hinterland is lower than that of the edge. Aeolian soil particles are composed of very fine sand-fine sand-middle sand, and the northern part is thicker than the central part and the southern part. The average value of φ1 in the sandstones between the ridge and the ridge of the individual ridge is the highest, and the average diameter of the ridge is the largest. In the north, sandy soil is poorly sorted, the vast majority of which are extremely skewed and the kurtosis is very narrow. The middle and southern boulders have medium and better seismograms with narrow kurtosis and near-symmetry distribution. The sandy soil in the hinterland of the desert had lower total salt content and moderate pH value, both of which had a certain positive correlation with the degree of sand ridge fixation. Aeolian soil organic matter, N, P, K and other nutrients is low. In contrast, the contents of total K and organic matter in the northern aeolian sandy soil were higher than those in the middle and southern parts, while the organic matter and total N content in the ridge-covered ridge and ridge with the lush vegetation were generally higher than those in the fixed and semi-fixed ones. The differences of local meteorological conditions, microtopography and vegetation status are the important factors that cause the spatial differentiation of the above-mentioned physical and chemical properties in sandy desert.
