为了客观、定量地评价城市景观水体的表观质量，提出了一种基于反射光谱的水体表观质量的测量和评价方法。在光学暗室中，利用卤素灯模拟日光照明，使用光谱仪测量水体的反射率和反射光谱数据，定量研究水体反射率特征值与水体浊度的关系、反射光光谱与水体色度间的关系，进而综合浊度与色度与表观质量的定量关系，定义了水体表观质量品质因子的计算公式，从而实现了定量评价表观质量的目的。该方法综合考虑了水体的浊度和色度信息对表观质量的影响，并可避免环境、时间等因素对测量的影响。

In order to evaluate the apparent quality of scenic water objectively and quantitatively, a method is proposed to measure and evaluate the apparent quality of scenic water. The scenic water is illuminated by halogen lamps in the dark room, while the reflectivity and reflection spectrum data is measured by a spectrometer. The relation between reflectivity and turbidity of water as well as the relation between reflection spectrum and chroma of water are quantified respectively. By which the apparent quality factor of scenic water is defined to evaluate the apparent quality of scenic water. The affects of the water turbidity and chroma are both considered in this method，and the influence of time and surroundings can be avoided.
