Traditional sampling and analyzing methods were used to establish the correlations between MIP-PID data and the concentration of BTEX in soil. Results showed that there is a polynomial regression between electrical signal obtained from MIP-PID and the concentrationof TBTEX in soil obtained from traditional technologies with equation as Y =-0.028X2 +166.92X +41 694；R2 =0.948 l，n =60.Three-dimensional image showing TBTEX electrical signal was obtained by the three-dimensional software package EVS- Pro based on 15 MIP borings data，and BTEX pollution plume was recognized in subsurface soil in this site.Key words：membrane interface probe（MIP）；portable gas chromatograph；expedited site assessment；BTEX；contaminated site随着我国产业结
