宁夏沙坡头野外观测站沙坡头人工植被固沙不同年限沙丘浅表层土壤粒级

本数据是宁夏沙坡头荒漠化数据中沙坡头人工植被固沙不同年限沙丘浅表层土壤粒级。统计了沙丘浅表层土壤的固沙年限、剖面层次、粒径-0.5-0.25、粒径-0.25-0.1、粒径-0.1-0.05、粒径-0.05-0.02、粒径-0.02-0.01、粒径-0.01-0.005、粒径-0.005-0.002、粒径-0.002-0.001、粒径<0.001、分形维数、相关系数。This dataset covers the soil particle size fraction data of shallow surface layers of sand dunes with different sand fixation durations via artificial vegetation, which is part of the desertification dataset of Shapotou, Ningxia. It records the sand fixation duration, soil profile horizon, multiple soil particle size fractions (0.5–0.25 mm, 0.25–0.1 mm, 0.1–0.05 mm, 0.05–0.02 mm, 0.02–0.01 mm, 0.01–0.005 mm, 0.005–0.002 mm, 0.002–0.001 mm, and <0.001 mm), as well as fractal dimension and correlation coefficient of the shallow surface soil of these sand dunes.
