영문 초록

Based on the importance of coastal saline-alkali soil remediation in Yellow River Delta, China, the Cl^-、Na⁺ transferring tendency in soil and the saline-alkali soil eco-remediation effects were researched by measuring soil Cl^-、Na⁺ 、soluble salt、 soil respire rate and dry biomass weight of reed, etc. periodically. The results shows: the concentration of irrigated soil Cl^-、Na⁺ and soluble salt were decreased 57.7-70%、45.7-47.1% and 53.2-59.7%, respectively, and soil salt decreasing level were little influenced by the hydraulic load, inundation depth varies in some degree, but it was influenced by dry-wet alternative irrigating mode The concentration of soil total nitrogen、organic mass、microbial respire rate, and the reed biomass above ground were increased averagely to 2.17、1.20、1.46 and 1.34 multiple respectively afterirrigation with wastewater, which have complex remediation effects on the coastal saline-alkali wetland, but there are some differences among the different irrigating crafts.
