PROBLEM TO BE SOLVED: To provide a structure for preventing wind erosion of soil which produces a sufficient wind erosion prevention effect, and to provide a method for preventing wind erosion of soil in which wind erosion prevention measures can be taken by a simple process.SOLUTION: A structure for preventing wind erosion of soil is made by forming a solidified layer 12, which is made by hardening magnesia, on the surface of soil 10. A method for preventing wind erosion of soil includes a step of adding powdery magnesia to water to prepare an aqueous solution of magnesia and a step of spraying the aqueous solution of magnesia on the surface of the soil 10, which allows the solidified layer 12, which is made by hardening magnesia, to be formed on the surface of the soil 10.COPYRIGHT: (C)2015,JPO&INPIT【課題】十分な風食防止効果が得られる土壌の風食防止構造と、簡易な工程で風食防止対策を行うことができる土壌の風食防止方法を実現する。【解決手段】土壌10の表面に、マグネシアを硬化させて成る固化層12を形成して成る土壌の風食防止構造。粉状のマグネシアを水に添加してマグネシア水溶液を作製する工程と、上記マグネシア水溶液を土壌10の表面に散布する工程を有し、以て、土壌10の表面に、マグネシアを硬化させて成る固化層12を形成する。【選択図】図1
