The Concept of Harmony in Aesthetics of Urban Landscape Bridge

With the development of economy and technology, people are increasingly demanding higher and higher living environment, leading to the artistic beauty of the city bridge continue to strengthen. Due to the subjectivity of human aesthetics, the current aesthetic system lacks systematic aesthetics. This paper puts forward the concept of the beauty of the landscape bridge from the epistemological point and the law of unity of opposites. Based on Lao-tzu's law of unity of opposites, we propose the aesthetic concept of "harmony" which contain "environmental integration harmony, humanities and history integration harmony, structural force balance harmony" triple aesthetic view.
