陕北神木矿区土壤颗粒体积分形特征及意义OA北大核心CSCDCSTPCD
Volume Fractal Characteristics and Significance of Soil Particles in the Shenmu Colliery in North Shaanxi Province
土壤由母质风化而成,土壤的颗粒组成继承了母质的许多特征,分形特征便是其中之一.土壤颗粒分形特征不仅影响土壤的水力状况和肥力特征,而且与土壤侵蚀和退化状况直接相关.利用MS 2000激光粒度分析仪,测定神木矿区凉水井煤矿、四道沟煤矿和红碱淖原生态保护区3个样区60个土样的粒径分布状况,运用土壤体积分形模型计算土壤颗粒体积分形维数(D),并分析土壤理化性质与D值之间的关系.结果表明:样区内D值在1.95～2.68之间,平均D值为2.42.3个样区平均…查看全部>>
Soil is produced from the parent material by weathering. Soil particle composition inherits many properties of parent material, one of which is fractal dimension. PSD affects not only the soil hydraulic- conditions and fertility, but also relates directly to the soil erosion and degradation. In this study, a laser particle size analyzer was used to measure the particle size distribution of 60 soil samples collected from the Iiangshuijing, Sidaogou and Hongji…查看全部>>
