Abstract

Chemical properties of groundwaters (6 - 7,20 - 30,60 - 70 m in depths) at sodic soil areas in Da'an City, Jilin Province were measured and soil salinization risk of using the groundwaters for irrigation was analyzed. The results show that 1)Groundwater, regardless of depth, takes on the characteristic of being soda-affected to a varying extent with NaHCO3 to be the dominant salt in the groundwater. 2) The groundwater within the depth of 0 - 30 m is quite high in HCO3- and Cl-. This kind of groundwater can not be used for irrigation, or else soil salinization and alkalization would occur. 3) The groundwater below 60 m in depth is good in quality and can be used for irrigation without the risk of soil salinization.
