• Inspired by transport system in trees, a two-way water and salt transport mechanism is realized in a structurally graded aerogel, enabling simultaneous fast water uptake and salt rejection.

• The horizontally aligned pore channels near the surface achieve excellent heat localization by maximizing solar absorption and minimizing heat loss.

• The integrated water, salt, and thermal transports impart an impressive evaporation rate of 1.94 kg m⁻² h⁻¹ in a 20 wt% NaCl solution for 8 h without salt accumulation.
