    • PROBLEM TO BE SOLVED: To provide a creation method for an artificial tideland which is equipped with the function of persistently maintaining a food chain intrinsic in the nature, and also to provide the artificial tideland. SOLUTION: Tideland deposit soil 10, the color of which has the high absorptivity of the solar radiation in wet conditions, is borrowed in an intertidal area on coastal soil 6 which is gently inclined over the vertical direction of the intertidal area. The temperature of coastal seawater 1 is increased by repeating the absorption of the solar radiation by the deposit soil 10 at low tide and the transfer of heat to the seawater 1 from the deposit soil 10 at high tide. Preferably, the lightness of the tideland deposit soil 10 in the wet condition is brought nearer to black than to white, and the color of the deposit soil 10 is adjusted by mixing a carbon granule, a dye-mixed concrete granule and/or sulfide-mixed dredged soil together. More preferably, the coastal soil 6 is enclosed with a wave-dissipating wall 4 with an opening, and the temperature of the seawater 1 in the wave-dissipating wall 4 is increased while ocean waves toward the costal soil 6 from the outside of the wave-dissipating wall 4 are suppressed. Desirably, the area of a sea surface inside the wave-dissipating wall 4 at low tide is set at 40% or less of the area of the sea surface at high tide. COPYRIGHT: (C)2007,JPO&INPIT
