该文对泥质海岸盐碱地土壤经不同方式整地４年后，土壤物理性状的变化进行了外业调查与室内分析。结果表明，经过台田、台穴、条田、大坑等方式整地后，土壤总孔隙度都有不同程度的提高，其中以台穴整地增幅最大。但这４种整地方式对土壤非毛管孔隙度没有实质性改变；和台田、条田、大坑相比较，台穴整地最大程度地改善了土壤的持水性能，而且土壤的三相比也接近理想状态。
This paper carried out field investigation and laboratory analysis on the changes of soil physical properties after four years of soil preparation by different ways in saline-alkali soils of muddy coast. The results showed that the total soil porosity increased with different degrees after land preparation by Taitian, Taixia, Yantian and Taikeng. However, these four kinds of land preparation methods did not change the soil non-capillary porosity substantially. Compared with Taitian, Tiantian and Taikeng, the soil-water-holding capacity was improved to the greatest extent by site preparation, and the soil three-phase comparison Close to the ideal state.
