根据嫦娥一号探月卫星获取的近月空间太阳风离子流量数据的特点，提出了对该数据的一种可视化表达方法。该方法首先从一个月的太阳风离子流数据中分离出向阳面或背阳面数据，从每一条记录中抽取所需的能级部分对其流量求和作为该记录的流量强度；根据当时卫星星下点的经纬度坐标将其投影到月球的均匀经纬度网格中，并求出每个网格中的平均离子流量强度，然后对该经纬度网格进行一种地图投影并选择一种色彩方案以表示不同强度的流量，从而得到离子流量在月表向阳面或背阳面的直观可视化结果。借助该方法能够对大量的太阳风数据在月面附近空间分布的总体变化趋势及特点进行显示与分析。实际数据实验结果验证了该方法的有效性。

Based on the characteristics of the solar wind ion flux data fetched by Chang’E-1 (CE-1) moon-orbiting spacecraft, a new visualization analysis method for these data is developed. First, all the data fetched in a month is separated depending on whether they are obtained on the day-side or the night-side of the moon. Then the total flux intensity distributed in certain energy levels is calculated as the sole flux intensity value for each data record, and these flux intensity values are projected to an even longitude-latitude grid of the moon surface and an average intensity value is calculated for each grid which has multiple intensity values projected in. Finally after a map projection, e.g. Hammer projection to give a more conventional representation of the moon surface and a color theme is chosen to represent different intensities of ion flux, and so an intuitive visualization result of the distribution of ion flux on the day-side or the night-side of the moon in a month is obtained. By using this method it is possible to visualize and analyze the mass data of the distribution and fluctuation of solar wind ion flux in cislunar environment. The validity of this method is proven by the results of actual experiments.
