摘　　要：月球尘埃研究具有重要的科学和工程价值。目前对月球尘埃运动规律、运动机理等的了解非常有限,对尘埃运动物理参数缺少系统的定量测量,严重制约了月球尘埃的科学研究。阿波罗17号宇航员观察到的月尘扬起及其物理机制迄今为止在科学上仍然是一个谜。中国的嫦娥三号月球探测任务得到了月面上的尘埃沉积数据及尘埃活动高度数据,表明尘埃活动具有显著的地域差异。在嫦娥五号采样返回任务中将研究月尘带电方面的物理特性。探月后续任务中如果能够在高纬度地区首次系统地定量测量月尘运动的物理参数,将会揭示不同经纬度区域、不同太阳光照条件、不同太阳风条件、不同地形条件下的尘埃活动规律及其关键影响因素,对高精度数值模型的建立及其参数选择提供定量限制,必将取得新的重要科学发现。Lunar dust research has important scientific and engineering values. Although it has been studied for several decades, the transportation of natural dust activity near the Moon surface and its physical mechanism remain unclear due to the lack of quantitative measurements of relevant physical parameters, which is the bottle neck of lunar dust research. So far, Apollo’s lunar dust observations still remain a scientific mystery. With China’s Chang’e 3 lunar exploration data, scientists have obtained the dust deposition rates and maximum levitated height on the lunar surface. Compared with the previous Apollo measurements, these results indicate that the dust activity has significant regional differences. In Chang’e 5 lunar mission, the in-situ charging properties of levitated dust will be measured. To further promote the lunar dust research, it is very important to systematically and quantitatively measure the physical parameters of the lunar dust transportation in the high-latitude region in the future lunar missions, which will be vital to reveal the physical mechanism of dust transportation under different influence factors such as different latitude and longitude regions, different solar conditions, different solar wind conditions, and different terrain conditions. These measurements will provide quantitative constraints in theoretical models and will surely lead to new and important scientific discoveries.
