Abstract:

The saline-alkali lands in Jilin province widely distribute in the arid and semiarid area of the western ar- ea. In recent decades， the saline-alkali level in these areas becomes worse and worse with high speed due to the effect of nature and human factor. The continuous increase in salinization and area had leaded the larger difficulty in management and higher cost， which seriously restrict the increase of output of the grain and purveyance in Jilin province. This paper described the efficiency in the saline-alkali management and the main problems， and put forward some countermeasures and suggestions for the land treatment.
