In this paper the Mueller polarimetry is applied to study the four natural samples in visible (λ = 632.8 nm): soil, sand, clay and moss. To quantify separability of these samples based on their Mueller matrices we analyze their experimental Mueller matrices by calculating a number of single value depolarization metrics (degree of polarization, average degree of polarization, depolarization index, Q(M)-metric) for each sample in in-plane and out-of-plane geometry of experiment. The results obtained show that all depolarization metrics are sensitive to the sample's polarization properties. The most effective identifier is Q(M)-metric in both experimental geometry.

本文采用Mueller旋光法研究了可见光（λ= 632.8 nm）中的四个自然样品 ：土壤，沙子，粘土和苔藓。为了基于这些样本的Mueller矩阵来量化这些样本的可分离性，我们通过计算每个样本中的多个单值去极化度量（极化度，平均极化度，去极化指数，Q（M）度量）来分析其实验Mueller矩阵。实验的平面内和平面外几何形状。获得的结果表明，所有的去极化指标对样品的极化特性均敏感。在两个实验几何中，最有效的标识符是Q（M）度量。
