- Title:
- THE SOIL PHYSICAL PROPERTIES WITH RELATION TO THE LOESS GENESIS IN THE LOESS REGION
- 摘要:
- 该文主要讨论了在陕、甘、宁境内作为黄土风成成因的主要颗粒组成从北向南或从西向东的分布规律，以砂粒、粗粉粒、粘粒及物理性粘粒四种粒级作为黄土风成成因的主要指标粒级，并讨论了随着土壤颗粒的变化，而产生的土壤一系列物理性质的变化：土壤比重愈向南愈大；土壤容重则是最南部及最北部最大，而中间过渡地带较小；对于破坏土壤(无结构的土壤)，土壤质地愈粘重，渗透性能愈差，质地愈轻则渗透性能愈好，而对于有结构的原状土壤则恰好相反。另外，黄土地区的土壤水分常数如最大吸湿水、凋萎湿度、自然含水量及田间持水量亦是从北向南相应的逐渐递增变大，然而毛管持水量则是最南部及最北部较小，而中间过渡地带最大，和土壤粗粉粒分布规律恰相吻合。
- Abstract:
- This article principally discusses the distributive rules of fine sand, coarse silt,clay and physical clay of soil mechanical composition in the loess region,from the northern desert to the southern Qingling Mountains. The distributions of above four different particles have marked regula-rity,and therefore they may be made as an index of the loess aeolian genesis.The clay(<0.001mm)and physical clay(<0.01mm)content are gradually increased from the north to the south,but on the contrary the fine sand(0.25-0.05mm)is gradually reduced.But the coarse silt(0.05-0.01mm)at certain area getting southward is increased by 55-65% in total content,then the coarse silt is gradually reduced.Them distribution of above four different particle will influence on the soil; general physical properties9 such as soil specific gravity,soil bulk density,soil porosity,soil permeability,and soil moisture constants.
