  1. Note: Data are mean ± standard deviation. The different uppercase letters (A, B, C, and D) in the same soil depth indicate significant differences between sample plots, while different lowercase (a, b, c, d) letters in the same sample plot indicate significant differences between different soil depth (p < 0.05). UP, Ulmus pumila forest; PM, Pinus sylvestris var. mongolica forest; PS, Populus simonii forest; CK, bare sandy land). The figures and tables below also apply.
