摘　　要：地球物理工作的多样性、反演推断的多解性和反演精度的不确定性均能影响找矿效果。这里主要从有限元网格、平滑度约束、收敛标准、梯度约束等几方面提高反演精度入手,从而实现精细化反演,研究成果能对内蒙古草原覆盖区下一步找矿工作起到指导作用,提高地质找矿的成功率。The diversity of geophysical works,the multiple solutions of inversion inference and the uncertainty of inversion accuracy can affect the prospecting effect.This paper mainly improves the inversion accuracy from the aspects of finite element mesh,smoothness constraint,convergence standard and gradient constraint to realize fine inversion.The research results can guide the next prospecting work in the grassland covered area of inner Mongolia and improve the success power of geological prospecting.
