Table 1. Parameters of the responses of the GPP against environmental factors.

	GPP to R_n		GPP to T_air				GPP to VPD
Wulanwusu	GPP_max	b	GPP_max	K₁	K₂	K₃	GPP_max	K₁	K₂	K₃
Wulanwusu	0.72	22	0.70	97.43	18000	29	0.74	1.1	419.17	22

GPP_max is the saturation point of GPP; b is the rate of GPP; k₁ and k₂ are the dispersion parameters; and k₃ is the optimal value of VPD or T_air.
