摘要: 月表光度行为描述了月表物质反射的太阳光随入射、出射和太阳相角的变化,其反射率的不同取决于月壤颗粒大小、粒子形状、透明度、孔隙度、表面粗糙度等因素。为了分析月表光度行为,了解区域反射率差异原因,本文以Apollo16登月区为例,使用M3(moon mineralogy mapper)数据反演Hapke模型物理参数,并分析了Hapke模型光度参数对二向性反射率的影响程度。反演结果显示,本文研究区域光度参数b、hS变化很小,光度参数w有一定的变化;表明本文研究区域反射率不同主要是w的差异造成的。研究区域月壤中各类矿物颗粒的前向散射占主导地位,月壤结构和粒径总体相近,但在孔隙度、风化层填充物状态及表面粗糙度等因素中至少有一种因素存在差异。
