| Based on the measurement of salt content and electrical conductivity in soda solonetz soil as well as in groundwater in Da'an City,Jilin Province,the relationship between the salt content and electric conductivity was determined.The results show: 1) Both the EC of soil extract and groundwater were linearly related to their respective salt contents.2) The regression equation between the electrical conductivity(y) and the soil salt content(g/kg) (x) was y=0.201+0.092x (r=0.991,n=50,p<0.0001).3) The regression equation between the electrical conductivity(y) and the salt content(g/L)(x) of groundwater was y=-0.393+(1.523)x(r=0.997,n=18,p<0.0001).4) The soil salt content calculated based on the electrical conductivity agreed well with the measured values,and the relative error was less than 7% mostly.5) The relative error of the salt content calculated based on the electrical conductivity to the actual salt content of ground water was less than 5% generally.It was concluded that the regression equations based on statistical analysis could be used to estimate the electrical conductivity and salt content of soda solonetz. |
