摘要
地面上的矿物或污染物元素主要是随水系而运移的。因此,利用自然水系网信息来定量分析元素沿水系的迁移、分散,对于地质找矿和环境保护都具有重要意义。在研究应用主概率权模拟模型产生自然水系网的基础上,提出了元素在水系网中运移的计算方法,结合所模拟出的水系网,具体分析了元素在其中的迁移、扩散情况,给出了正问题和反问题的计算结果。结果表明,正、反问题的求解具有一致性,方法是有效、可行的。
The mineral or contaminant element on ground is mainly transported with water. It is very important for seeking mine and protecting environment to analyze the move and distribution that element is along water networks. Based upon the information of natural drainage system we created, we established the calculation method of moving element in the system and gave the calculation of direction and indirection. Results show that the calculation has consistency and the method is effective and feasible.
