  再分配
    Secondly, approaches by which soil erosion affects soil quality have been illustrated and confirmed. Results of analysis indicated that, erosion increases correspondingly the particles (>0.2mm) of soil, while the particles (<0.02mm) correspondingly decreased. As the particles (<0.02mm) have enriched nutrient, the redistribution of carbon and nutrient is affected by erosion.
    二、明确了侵蚀作用影响土壤碳和养分含量的具体途径:分析表明,侵蚀作用使坡面土壤中大于0.2mm的颗粒含量相对增高,而大量富集养分的、小于0.02mm的颗粒含量则相对减少,从而影响了养分在坡面上的再分配

    Moreover, the larger the rainfall intensity, the smaller the wetting front difference was at the top and the end of the slope. With the larger rainfall intensity, both the difference of soil water content and its descending trend between soil layers became more obvious during the redistribution process on slope land.
    此外,雨强越大,坡顶与坡脚湿润锋深度差异越小,坡面再分布过程的土壤含水量在各层的差异和递减趋势越明显.

A Study of the Redistribution Conditions of Carbon Black Particles from the Bulk to the Interface in Heterogeneous Polymer Blend
      
The redistribution conditions of carbon black particles to the interface between polymers were studied based on the measurement of the value of superadditive conductivity of several heterogeneous polymer blends filled with powdered carbon black.
      
The redistribution of carbon black from the polymer phase that has low ability to wet the powder proceeds efficiently only to the boundary with polymer having better wetting ability.
      
As the storage time of the system increases, the spectrum of diffusion coefficient values varies, thereby indicating the redistribution of PEG400 molecules in the blend with PVP.

This paper presents a approach of determining unsaturated hydraulic con- ductivity and diffusivity based on the redistribution of soil moisture. The suggested formulas of calculating hydraulic conductivity and diffusivity, based on the function relationship between average wetness ((?)) of wetting profile and wetting front and the one-dimensional equation of vertical unsaturated flow, are: K(θ)=HΔθVC(θ)/(a_1bθ(1+b1)+HC(θ)) and D(θ)=HΔθV/(a_1bθ(1+b1)+HC(θ)) respectively. The accuracy of the method was verified...

This paper presents a approach of determining unsaturated hydraulic con- ductivity and diffusivity based on the redistribution of soil moisture. The suggested formulas of calculating hydraulic conductivity and diffusivity, based on the function relationship between average wetness ((?)) of wetting profile and wetting front and the one-dimensional equation of vertical unsaturated flow, are: K(θ)=HΔθVC(θ)/(a_1bθ(1+b1)+HC(θ)) and D(θ)=HΔθV/(a_1bθ(1+b1)+HC(θ)) respectively. The accuracy of the method was verified by soil moisture dynamic model- ing. The results show that the accuracy is satisfied. The measurement range are from θ=0.08 to θ=0.28 for heavy loam and from 0.08 to 0.22 for light loam. The method is accurate, convenient and usable for the loessial soils.

本文根据土壤水分的再分布过程提出了推求土壤导水率和水分扩散率的方法,在湿润剖面平均湿度(θ)和湿润锋湿度(θ)有确定函数关系和一维垂直非饱和流方程的基础上,提出的计算导水率和扩散率的公式分别为K(θ)=HΔθVC(θ)/[a1bθ(1+b1)+HC(θ)]和D(θ)=HΔθV/[a1b(1+b1)+HC(θ)]。该方法对所研究的土壤测定范围是,重壤土0.08≤θ≤0.28,轻壤土0.08≤θ≤0.22。本文用土壤水分动态模拟检验了方法的准确性,其结果令人满意。

The partitioning of N from various sources within different parts of rice plant was studied.The result indicates the different N-supply characteristics of soils and fertilizers and the redistribution of soil and fertilizer-N,which went into the plant“pool”in different times with different speed and intensity.The evaluation of ferrilizing techniques are of practical mearling when the ratio of grain N%dff(or dfs) values to straw dff/dfs values which show the magnitude of contribution from different N sources to the rice grain,and the fertilizer N balalice in the agricultural ecology were concerned.Fertilization increases both soil-N up-take and crop yield by changing the soil N supply characteristics.However,the “priming effect”may augment the soil N loss through v olatilization.

Three pedons of typical albic soils in the Three River Plain of Heilongjiang Provence were chosen for the study of elemental geochemistry. The background levels of trace element and rare earth element were established for these undisturbed soils. The redistribution and differentiation of these elements during soil forming process were analyzed.We found that Br, Cl, I and Hg were possibly accumulated in Ah Horizons, due to dust deposition and their affinity for soil organic matter. Mn, As, Sb, Th and U were associated with amounts of oxalate and dithionite extractable Mn and Fe in E horizons. The Cr, Rb,St, V and Zn Were closely related to clay particles and enriched in Bt2 horizons. The B, Ba, Hf, Sr, Ti and Zr exist generally in weathering-resistant minerals and have a relatively even distribution in soil profiles.The rare earth element (REE) contents were higher in clay particles than in soil samples.The gadolinium break, even-odd and tetrad effects were observed on the normalized REE Curyes, indicating the redistribution and differentiation of these elements occurred during soil formation. The cerium in E horizons was found to be positively anomalous on normalized curve.which might be attributed to the cerium enrichment in Fe and Mn concretions. The normatized REE patterns among different horizons may serve as an alternative indicator for parent material uniformity. The high ratio of Σ La to Σ Lu of soils in the study indicates a warm,humid geochemical weathering environment in the past.

本文研究了三江平原三个典型白浆土剖面的元素地球化学特性,建立了白浆土中30余种微量元素和10余种稀土元素的背景值,并分析了这些元素在成土过程中的再分布和分异。研究发现,Cl、Br、I和Hg在表土层富集。Mn、As、Co、Sb、Th和U在Fe和Mn结核富集的白浆层中含量较高。Cr、Rb、Sc、V和Zn在淀积层中积聚。而B、Ba、Hf、Sr、Ti和Zr一般存在于抗风化矿物中,具有相对均一的剖面分布。稀土元素在粘粒中的含量大于其在土体中的含量。标准化曲线中白浆层Ce的正向异常,可能是由成土过程中元素Fe、Mn结核淀积和富集作用引起的;Gd间断、奇偶效应和四分现象的出现,表明风化过程中稀土元素间出现分异;稀土元素含量的分布形态,可作为岩性连续性的一个有用指标。白浆土中轻稀土元素含量之和与重稀土元素含量之和的比率较高,表明过去地球化学风化的温暖和湿润环境。
