Urban landscapes are defined as the outdoor space of whole cities, which consist of natural and artificial elements. Building landscapes, including the vegetation around the construction, are the main subject of urban environment. Urban landscape esthetics have been studied to improve urban appearances and protect the living environment, and provide a quantitative approach for urban planning. Most of the existing research has focused on esthetics evaluations of the natural landscape, whereas urban landscapes were more difficult to quantitatively assess because of their complex compositions. It is important to explore how different esthetic features influence the visual quality of landscapes and to quantify the features by using landscape ecology indicators to evaluate the landscape quality. Considerable research has verified the relationships between quantitative landscape indices and esthetics. Based on the results of the esthetic assessment of landscapes, we summarized five urban landscape esthetics features (naturalness, openness, diversity, peculiarity and harmony) from the view in urban spaces, and combined the two and three-dimensional landscape indices concepts from landscape ecology to develop quantitative indicators of urban landscape esthetics features. We used landscape indices as references, and explained the definition and formula of each index clearly. Quantitative indices provide rapid ecological evaluations for effective urban planning and design.
