摘要
矿产地球化学采样密度受到地球化学景观、水系分布和地貌发展阶段的控制,分形面密度、流域面积比和比降系数揭示了三者的形成机制。采样密度因素模型是采样密度理论的基础,可以指导矿产地球化学调查采样密度和采样布局的制定。
Sampling density in geochemical mineral exploration is controlled by such factors as geochemical landscape, stream distribution and geomorphic evolution. Fractal area density, drainage area ratio and altitude coefficient can reveal the forming mechanism of these three aspects. As the foundation of the sampling density theory, the factor model of sampling density could guide the formulation of sampling density and sampling layout in geochemical mineral exploration.
