Responses of Xilingol Fractional Vegetation Cover to Climate Change and Human Activities

Table 1

Evaluation methods for the relative effects of climate change and human activities on fractional vegetation cover in various scenarios.

Vegetation change	Scenario	Cslope	Hslope	Relative effects of climate	Relative effect of human	Description
Vegetation improvement regions	Scenario 1	>0	>0			Climate change and human activities jointly increase fractional vegetation cover and their relative effects are the percentage change in cover
	Scenario 2	>0	<0	100		Climate change increases fractional vegetation cover
	Scenario 3	<0	>0		100	Human activities increase fractional vegetation cover
Vegetation degradation region	Scenario 1	<0	<0			Climate change and human activities jointly decrease fractional vegetation cover and their relative effects are the percentage change in cover
	Scenario 2	<0	>0	100		Climate change decreases fractional vegetation cover
	Scenario 3	>0	<0		100	Human activities decrease fractional vegetation cover

Note. H_slope is the slope of the cover residual caused by human activities; C_slope is the slope of the cover residual caused by climate change; ΔC_pre is the difference in the predicted cover caused by climate change at t + i and t; ΔC_hum is the difference in the predicted cover caused by human activities at t + i and t.
