Fig. 4 Spatial distribution of the annual average water yield depth and annual average water conservation depth of the IRD in 1975 (a1 and b1), 1985 (a2 and b2), 1995 (a3 and b3), 2005 (a4 and b4), 2015 (a5 and b5), and 2020 (a6 and b6). Note that the blank area in each figure is the Lake Balkhash, and the calculations of the water yield depth and water conservation depth in the Lake Balkhash region were excluded.
