, 2008 应用土壤颗粒的重量与粒径分布原理来描述了古尔班通古特沙漠地风沙土壤颗粒的分形特征。通过对10种样品颗粒的机械组成进行分析,分别计算出了它们的分形维数(D=2.3237～2.9347),并分析了其与流动风沙土、半固定风沙土和固定风沙土之间的关系。分析结果表明,风沙土壤结构具有明显的分形特征,其粒径分布分形维数为2～3。土粒表面分形维数与2～0.2mm间的土粒含量存在显著的负相关;而与0.02～0 ...

, 2016 干旱荒漠区广泛分布着生物土壤结皮（BSCs），探索BSCs对土壤入渗的影响，对于深入揭示荒漠地区水分循环过程具有重要的意义。本文以古尔班通古特沙漠南缘的BSCs为研究对象，基于野外原位实验与室内模拟实验等方法，探究藓类、地衣和藻等3种类型BSCs覆盖下风沙土的入渗特征。主要结论如下 1、BSCs覆盖对风沙土水分入渗过程有着重要影响：与无结皮覆盖的风沙土对照相比，3种类型BSCs均显著降低了风沙土初渗速率，藓类结皮、地衣结皮、藻结皮覆盖下初渗速率降低幅度依次为36.10%、46.42%、50.39 ...
