The soil had the alkalize characteristic, and the decisive factors were terrain, texture and precipitation, so before the haloxylon ammodendron settled down, the soil had the alkalize characteristic, and the haloxylon ammodendron was alkali-resistant plant, but if the total alkalinity excessively high, the haloxylon ammodendron also grew difficulty.

土壤具有碱化特征，主要是由地形、质地、降水等结构性因素决定的，由此得出荒漠植被梭梭定居之前土壤就具有了碱化特征，梭梭是耐碱性荒漠植被，但总碱度过高的区域梭梭也难以生长，因此土壤酸碱度仍然是该区域影响梭梭生长和分布的重要因子。

This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.

与其它剖面相比，彭阳剖面粒度总体上要比东部的洛川、西安，甚至西部的兰州、新疆东湾要粗；CaCO_3平均含量不仅高于黄土高原中部，也高于高原西部，反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用；易溶元素含量在剖面10m处快速升高，淀积特征明显，反映出黄土受现代淋溶成土作用影响较大，黄土直立、疏松、多孔特性和高温与多雨组合的气候特点，使得元素淋溶、淀积的强度和深度超出了传统的认识和判断；烧失量与其它指标相比，不仅能区分冰期、间冰期；而且能够区分出次一级的冰阶、间冰阶，有较高的分辨率；土壤发育指数、红度能够反映土壤强度差异，是反映气候波动的较好指标；然而，磁化率不能反映古土壤S_8的存在，且S_7的磁化率在全剖面中最高，这与大多剖面S_5磁化率最高的特点不一致。4。

When they move around in the soil the tunnels they make aerates the soil and improves the texture.

当他们走动的泥土隧道使aerates土壤质地和完善了。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
