(a): Scatter plots of soil ecoenzymatic stoichiometry among different zones and different soil layers, (b): Soil microbial C limitation, quantified by vector length (derived from the enzyme vector model). Vector length is calculated as the Euclidean distance from the origin in a 2D space defined by ln(BG/ALP) (x-axis) and ln[BG/(NAG + LAP)] (y-axis), where longer lengths indicate stronger C limitation. (c): Soil microbial N/P limitation, quantified by vector angle (derived from the enzyme vector model). Vector angle is calculated as the arctangent of [ln(BG/ALP)/ln(BG/(NAG + LAP))], where angles < 45° indicate N limitation and angles > 45° indicate P limitation (d) linear regression relationship between soil microbial C limitation and microbial N/P limitation. The soil microbial C limitation is represented by the vector length, while the soil microbial N/P limitation is represented by the vector angle. Angles of < 45° indicate N limitation, and angles of > 45° indicate P limitation.
