Habitat	pH	EC (µS cm⁻¹)	WC (%)	NH₄⁺-N (mg g⁻¹)	NO₃⁻-N (mg g⁻¹)	TC (mg g⁻¹)	TN (mg g⁻¹)
GTZ	8.12 ± 0.05b	135.19 ± 20.38a	9.65 ± 3.56b	0.001 ± 0.0003a	0.003 ± 0.0006b	16.74 ± 2.61b	0.60 ± 0.10b
MR	8.24 ± 0.07a	89.13 ± 14.77b	7.09 ± 4.02b	0.001 ± 0.0003a	0.006 ± 0.006b	23.59 ± 5.09b	1.33 ± 0.61b
AM	7.79 ± 0.10c	94.34 ± 22.83b	26.30 ± 5.47a	0.002 ± 0.0007a	0.017 ± 0.009a	41.13 ± 10.24a	4.34 ± 1.42a

pH represents potential hydrogen, EC represents electrical conductivity, WC represents water content, NH₄⁺-N represents ammonium content, NO₃⁻-N represents nitrate content, TN represents total nitrogen content, TC represents total carbon content. GTZ, MR, and AM represent the glacier terminus zone, moraine ridge, and alpine meadow, respectively. Each value represents mean ± SD of seven individual replications, and different lowercase letters in each column indicate significant differences (Tukey’s HSD test: P < 0.05)
