On the analogy of Lanjelie’s index the stability indices for components of calcium- hydrocarbonate systems (СHCS) have been introduced: H+, CO2, НСО3-, СО32- and Са2+ according to the scheme I = X/Xs, X, Xs – current and equilibrium parameter value. The procedure of indices calculation has been developed, the links between them have been determined. The simplified calculation scheme for quasiequilibrium processes for Lanjelie’s index IL = -log(H/Hs) and others has been suggested. The ratios obtained are used to experimental analysis of the processes in model СHCS. They describe logically the system behavior. 

Key words: stability indices, calcium-hydrocarbonate systems.
