In order to reveal the effect of different measures on improvement of the saline-alkali soil fertilityand select the effective and fast improving measures. The distribution of organic matter and absorbable nutrition con-tent, total soluble salts, the changes in micro-aggregates and mechanical composition under different amend mea-sures were studied in the paper. Four treatments were adopted, i.e., 3 year organic fertilizer amendment（T₁）, 6 yearorganic fertilizer amendment（T₂）, 3 year Al₂（SO₄）3amendment（T₃）, 3 year organic fertilizer add Al₂（SO₄）₃ amendment（T₄）. Results showed that the organic matter and absorbable nutrition promoted rapidly, the content of salt decreasedand the physical of soil improved significantly in different amendments. The content of organic mater in 0~10 cmlayer was significant different among each treatments, and T₄ treatment is the best. It is the same with absorbable nu-trition besides available P. The total desalting effect were T₄＞T₃＞T₂＞ T₁. From the structure coefficient and disper-sion, the T₄ treatment was significantly better than others. Totally, organic fertilizer add Al₂（SO₄）₃ was the best treat-ment to achieve a rapid amendment objective.
