2.6 Spatial Pattern Change
The distribution probability of T. sinense underwent
reclassification, and a grid calculator was employed to delineate the
distribution change layer of T. sinense between historical or
future periods and current climate scenarios. Based on the grid values,
four types of distribution area changes in T. sinense were
redefined: retention (3), additions (2), losses (1), and non-suitable
(0). The suitable area for each type was determined by calculating the
proportion of each value.
