distributed in different AEZs, but the grassland area in different AEZs differs a bit
more greatly in the result obtained with the GCAM model. In addition, the results
obtained with the two models show that the forestland is mainly located in AEZ9-
AEZ12, while the shrubland and cropland are mainly in AEZ7-AEZ13. What's
more, the built-up land, the area of which is the smallest, is generally distributed in
AEZ10 (Fig. 2.5 ). Comparing the results obtained with the two models, we found
