表2 植被NDVI变化的驱动因素判定标准及贡献率计算方法

Tab. 2 Identification criterion and contribution calculation of the drivers of NDVI change

slope(NDVI_obs)^a	驱动因素	驱动因素的划分标准		驱动因素的贡献率(%)
slope(NDVI_obs)^a	驱动因素	slope(NDVI_CC)^b	slope(NDVI_HA)^c	气候变化	人类活动
> 0	CC & HA	> 0	> 0	$\frac{slope (NDV I_{CC})}{slope (NDV I_{obs})}$	$\frac{slope (NDV I_{HA})}{slope (NDV I_{obs})}$
	CC	> 0	< 0	100	0
	HA	< 0	> 0	0	100
< 0	CC & HA	< 0	< 0	$\frac{slope (NDV I_{CC})}{slope (NDV I_{obs})}$	$\frac{slope (NDV I_{HA})}{slope (NDV I_{obs})}$
	CC	< 0	> 0	100	0
	HA	> 0	< 0	0	100
