PROBLEM TO BE SOLVED: To provide a soil erosion-preventing method capable of preventing soil scattering over a long period and also preventing soil erosion due to rainfall or flood to solve such a problem that when the soil is polluted by pollutants, such as heavy metals and harmful organic substances, until conducting a decontamination work, the pollutants together with granular particles such as sands scatter from the surface portion of the soil to nearby area.SOLUTION: A soil erosion-preventing method includes spraying a mixed aqueous solution containing an ionic polymer comprising a specific anionic monomer, a cationic polymer or a polycondensation polymer, and inorganic salts. The ionic polymer is preferably a dispersion liquid of polymer particulates obtained by making a polymer dispersant soluble in an aqueous solution including inorganic salts coexist, and by dispersion-polymerizing while agitating. |
