- 摘要:
- 对焉耆盆地白刺灌丛沙堆不同演化阶段和沙堆间低地土壤理化性质进行分析。结果显示：（1）白刺灌丛沙堆不同演化阶段土壤粉砂、黏粒、有机质和养分含量均高于沙堆间低地，而土壤砂粒含量和pH值低于沙堆间低地；从白刺灌丛沙堆发育到稳定阶段，土壤砂粒含量和pH值逐渐降到最小值，而粉砂、黏粒、有机质和养分含量达到最高值，从白刺灌丛沙堆稳定到活化阶段，土壤砂粒含量和pH值急剧增加，而粉砂、黏粒、有机质和养分含量大幅度下降；（2）从整个剖面来看，由于白刺灌丛沙堆侵蚀和堆积的差异，随着深度的增加砂粒含量先减后增，而pH值、粉砂、黏粒、有机质和养分含量先增后减；0—15 cm土层砂粒含量最高，而15—45 cm土层最低；0—15 cm土层pH值、粉砂、黏粒、有机质和养分含量最低，而15—45 cm土层最高；（3）白刺灌丛沙堆发育和活化阶段强烈的吹蚀不利于有机质的积累，白刺灌丛沙堆稳定后为降尘截存、凋落物积累和微生物的繁殖提供有力的保障，表层黏粒得以截存和地衣状薄层结皮形成，增加土壤的有机质和养分含量。
- Abstract:
- We chose Xinjiang Yanqi Basin as the research area and analyzed the different evolution stages of nitraria shrub dune and the physicochemical properties of between-dune lowland shrub dune soil. Results show that:(1) the silt, clay, organic matter and nutrient content of dune soil in different evolution stages were higher than the between-dune lowland, but the sand and pH values were lower; from development stage to the stable stage, the sand grains and pH values gradually reduced to the minimum, while the silt, clay, organic matter and nutrient content reached the highest values, from stable to the activation phase, sand grains and pH values increased sharply, and silt, clay, organic matter and nutrient content declined significantly; (2) from the entire profile view, due to the differences of erosion and accumulation of sand dune, with the increasing of depth, sand grains decreased first and then increased, while pH values, silt, clay, organic matter and nutrient contents were the opposite; the most sand grains were found in 0—15 cm soil layer, and the minimum was found in 15—45 cm soil layer; the lowest pH values, silt, clay, organic and nutrient content were detected in 0—15 cm soil layer, the highest values were found in 15—45 cm soil layer; (3) sand dune development and activation stage deflation are not conducive to the accumulation of organic matter, sand dune stabilizing will provide the strong protection for the dust sequestration, litter accumulation and microbial growth, it can improve clay surface sequestration, lichen like thin crust formation, and can increase soil organic matter.
