Type-B Nodule: The source of elements in the nodules comes from slow deposition of the overlying water and the diffusion of the pore water, which comes mainly from the double decomposition reaction of Fe, Mn oxides caused by the oxidation diagenesis of organic material in sediment and its forming process and distribution is controlled by pH in the pore water. There is no corrlation between distribution of the nodules and water depth, topograph.

A型结核主要分布于深海火山沉积环境区，受上覆水Mn〓和Eh制约；B型结核一方面由于在深海火山沉积环境区，受生物作用影响，另一方面在生物沉积环境区，又受火山作用影响，使此类结核的分布与大洋地貌和沉积物的关系不明显；C型结核主要分布在太平洋CCD范围内，受沉积环境上生物和活性有机碳的制约。

Because change of volume reflected eroding process of watershed and surface change reflected change of topography surface, this model described relationship between watershed topograph and erosion.iv As a quantitative index of wateshed topography, topograph fractal demension can represent surface shape information of watershed topography in the round. Reseach find that watershed model and actual watershed show good fractal character. Topography fractal dimension related with process of development of watershed physiognomy and represented degree of watershed development, v Sediment yield intensity of watershed model reflected erosion characteristic of watershed model in different development phase.

流域模型产沙强度的变化反映了流域模型在不同发育阶段的侵蚀特征，模拟试验研究结果表明：在整个流域模型地貌地貌的发育过程中，其产沙强度呈现由小到大，然后又逐渐减小的总体趋势，流域模型单位降雨产沙率及平均输沙率与地形分维数表现为Gaussian模型关系，其关系形式与结论3中相对体积和表面积之间关系相似，进一步说明了以地形分维数表达地形变化的合理性。

In order to remove different concentrations of suspended sediment, a serial connected system of emerging plants, floating-leaved plants and submerged plants based on spatial distribution of natural water body was constructed by aquatic marcrophytes, such as Cyperus alternifolius, Acorus tatarinowii, Trapa japonica, Ceratophyllum demersum, Hydrilla verticillata and Vallisneria spiralis. Sandy water then flew through emerging plants, floating-leaved plants and submerged plants.

根据自然水体湿生植物、浮叶植物以及沉水植物的空间分布规律，利用风车草、石菖蒲、菱、金鱼藻、轮叶黑藻和苦草等水生植物构建由挺水植物、浮叶植物到沉水植物的串联系统，含沙水依次流经挺水植物、浮叶植物和沉水植物，测定各级植物对泥沙的去除效果。
