| 摘 要： | 本文从微形态角度研究了海涂土壤在改土脱盐过程中土壤特性的变化。研究表明，滩涂土壤尚处于新成发育阶段和强烈积盐的生态环境中。耕作土壤腐殖质浸染程度提高，并形成程度不一的团粒结构和堆集孔隙，提高了土壤脱盐速率．另外，由于生态系统成熟度不同，成林、幼林及农田土壤的改土脱盐能力及熟化程度具有明显的差异．

| Abstract: | This paper deals with the variances of micromorphology features ofcoastal zonal soils during the amelioration and desalting processes. The results showed that the shoaly lands were still in a salification and entic stage. Due to the higher humus infection, the various degrees of granular structures and packing voids in cultivated soil formed and hence the soil desalting rates were increased. Further, there were some distinct differences in the desalting capacities and curing levels among mature forest soils,young forest soils and agricultural soils because of the various maturity of ecosystems. |
