Integral indices of the ecological state of soils, determined on the basis of the triad approach, were correlated with the categories of quality and degree of loading, similar to that described earlier (Terekhova et al., 2014). Soils from the test plots of Bishkek located at the distance of 150 and 500 m from the coal power station are of the IV quality category with a high degree of load, the ecological state of these soils can be described as "severely disturbed". While the soils located at 50 m distance from the plant are of the III quality category with an average load, the ecological state of these soils can be described as "disturbed". We believe that the triad approach to generalization of data allows us to obtain a more complete characterization of the ecological state of soils in comparison with the analysis of individual responses of biota representatives or chemical indices. The reported study was funded by ISTC (Project KR-2092) and RFBR according to the research project № 18-04-01218-a
