Abstract：According to the well-performed ionospheric heating experiments at Arecibo in the low latitudes as well as at TromsΦ in the high latitudes, the large-scale modification effects are simulated. The findings are extensively exploited to verify the validation of the proposed model by comparison to the experimental results. Further, a thorough research is carried out on the influences of the background electron density gradient as well as the ratio heating frequency fHF to the critical frequency f0F2 of ionospheric F2 region on heating effects. Conclusions are drawn as follows: A smaller electron density gradient of background ionospheric F region leads to a better ionospheric heating effect; During over-dense heating, the heating effects are enhanced if the ratio of fHF to f0F2 increases, which is limited by the resultant elevation of the reflection height. However, there might be a better ratio range with small values of the ratio of fHF to f0F2. Finally, how to select heating parameters efficiently under adverse conditions is analyzed so as to obtain relatively effective results.
