According to the view of energy, we put forward a new parameter-stable energy, which describe the stability from surface to the given altitude and its calculating method. By using the sounding data of Lanzhou meteorological station and the concentrations of air pollution of Lanzhou environmental station during 1988-1992, we have worked out 15 layers the stable energy from 300~1000 m and the correlation coefficients between stable energy and concentration of SO2, CO, NOX. The results are as follows:To describe the stability of lower air, stable energy is better than thickness and intensity of inversion layer. The annual change regular pattern of stable energy is the same as concentrations of air pollutant. Except for July, the correlation between stable energy and concentration of air pollutant have pass the significant level test at the α=0.01.
