| Abstract: |
| The soil water and salt transporting experiment was conducted to analyze the wetting front distance, water content profile features, salt content profile features, salt concentration, Na+ and Cl- concentration profile of soil with different infiltration amount of saline water. The results indicated that there was a linear relationship between infiltration amount and wetting front distance, the ratio of desalinized depth and wetting front distance was about 0.342. In addition, the salt concentration of top soil was determined by salinity of infiltration water. Therefore, infiltration amount influences not only wetting scope but also salt content of top soil. |
