摘　　要：随着中国城市化进程的不断推进与深入,城市空间中的自然山水景观视觉价值与重要性受到更多关注。以城市山体为研究对象,构建了一种基于混合精度模型的定量视觉分析框架,从"观"与"被观"2个方面提出了若干视觉量化指标。结合南京紫金山案例研究,从客观角度深入分析紫金山在南京老城中的空间视觉特征,利用基于混合精度模型的定量分析方法获得可描述这些特征的视觉量化指标,从而发现有潜力但被忽略的视觉廊道与观赏点,并针对部分道路及开放空间进一步提出了完善紫金山视廊体系的建议与策略。With the rapid growth of China’s urbanization, the visual value of the urban natural landscape has been receiving increasing attention. Therefore, this paper proposed a quantitative approach to measure the visual properties of urban mountains. This approach is based on multi-precision detailed models and contains several quantitative visual indexes to describe visual characters for both urban areas and urban mountains. Mount Zijin, Nanjing,was selected as the study case to perform the proposed approach.Based on visual indexes of Mount Zijin within the old city of Nanjing, several new view corridors were found. And the paper also presented a visual control strategy for some view corridors with street viewpoints.
