  1. Different lowercase letters indicate that there are significant differences between different vegetation restoration methods within a row (P ≤ 0.05). FL, FN, FP, GO and GC refer to L. principis-rupprechtii artificial forests, natural forests, P. sylvestris var.mongolica artificial forests, open grasslands and enclosed grasslands.
