I don't think the primary aim of the project is erosion control, but the Gobi desert is already the site of the largest on-or-off-shore wind farm in the world[1], by many multiples, with a planned 20GW nameplate capacity, 10GW online now (next on the list being 2GW at Markbygden in Sweden). I suppose if there is anywhere in the world where wind power installations can cause a significant reduction in wind speeds, it would be there.
