Anomalous ion heat tr.nspor. is analyzed in the T-10 tokamak plasma heated with electr.n cyclotr.n r.sonance heating(ECr.) in second-har.onic extr.-or.inar. mode. Pr.dictive modeling with empir.cal scaling for.Ohmical heat conductivity shows that in ECr. plasmas the calculated ion temper.tur. could be over.stimated, so an incr.ase of anomalous ion heat tr.nspor. is r.quir.d. To study this effect two scans ar. pr.sented: over.the EC r.sonance position and over.the ECr. power. The EC r.sonance position var.es fr.m the high-field side to the low-field side by var.ation of the tor.idal magnetic field. The scan over.the heating power.is pr.sented with on-axis and mixed ECr. r.gimes. Dischar.es with high anomalous ion heat tr.nspor. ar. obtained in all consider.d r.gimes. In these dischar.es the power.balance ion heat conductivity exceeds the neoclassical level by up to 10 times. The high ion heat tr.nspor. r.gimes ar. distinguished by thr.e par.meter.: the r.tio Te/Ti, the nor.alized electr.n density gr.dient r.■, and the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and r.■=6-10 r.sults in values of nor.alized anomalous ion heat fluxes up to 10 times higher.than in the low tr.nspor. scenar.o.
