摘　　要：利用电离层欧姆加热的理论模型和数值分析模型,根据数值模拟结果,对高频电波加热电离层的一级空间效应(主要是电子密度和电子温度的改变)进行定量分析,给出在不同地域(高纬区和中低纬区)、不同加热功率、不同加热频率(包括过密和欠密情况)和不同高度范围内,地基高频无线电波加热电离层引起的电离层主要参量的时空演化规律,以获取加热条件或参数的改变对不同区域电离层的加热效果。并结合国外相近纬度区、相近加热参数条件下的实验结果进行对比分析,给出了初步结论。A numerical heating model is developed in this paper. Based on the nu merical simulation results, the spatial effects of the ionosphere （mainly the change on electron density and temperature） heated by the HF pump wave are analyzed quantificationally. The space-time evolvement regulation on the main parameters of the ionosphere resulted by the HF heating waves under the different heat-conditions, just as different regions （high latitude and mid-low latitude）, different heating power or frequency （underdense heating and overdense heating） and different height regions are presented, and the heating effects in different regions under the different heating conditions have been pictured out. Finally, comparing the numerical results with the experimental one provides some primary conclusions.
