摘　　要：本文对距离加权法中如何确定最佳估值幂指数和估值影响域等方面作了合理改进,为该法的广泛应用创造了条件。通过与普通克立格法的交叉检验和储量计算结果的综合对比证实,距离加权法是一种比较适用于层状矿床储量计算的方法。In this paper the distance weighting method is improved at the following aspects: the determination of exponent N and the estimation influence range, etc. These improvements provide a basis for wide use in estimation of reserves of layered deposits. The comprehensive comparison of optimal examination and estimated results of reserves both using the ordinary Krige method and the distance weighting method concludes that the improved method introduced in this paper is a more proper method for estimation of reserves of layered deposits.
