| Abstract: | The paper mainly deals with the following questions: (1) The properties of salt-affected land and its distribution patternon the Loess Plateau. (2) Analyses of the formation and development ofsaline-alkali land. Chemical mechanism is adopted. (3) In the light ofaccumulation processes of salt,the causes of salt-affected land in the regionis offered. (4) The tentative plans for the amelioration of salt-affectedland on the Loess Plateau. |
