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.
