Landscape aesthetics, as an important branch of environmental aesthetics, should seek effective intervention of new ideas with epochal criticism on the basis of in-depth exploration of its historical form. Based on the vertical time axis, this study combed the traditional aesthetic theory and its application in landscape practice, summed up the transformation of landscape aesthetics from subject-object dichotomy to experience-based empiricism, and introduced ecological ethics and scientific knowledge into contemporary landscape aesthetics to determine its value orientation of the times, in order to provide theoretical reference for solving ecological crisis and expanding the study of landscape aesthetics.展开更多

The Chu bronze mirror carries a rich Jingchu culture connotation. Its superb craftsmanship,fine carved decorative patterns and inaage- rounded shapes reflect the mysterious religion belief, rigorous life attitude, romantic humanism and deep moral universe structure view of Chu people.It is the valuable cultural heritage that the ancestors left for the Jingchu land and the Chinese people. Digging the beauty of Chu mirror and its inheritance and transcendence, in the ＂global＂ and ＂globalization＂ context, conform to the issue of the 18th CPC National Congress ＂ improving the national cultural soft power, playing the role of the cultttral leading customs, educating people, serving the society and promoting the development＂ .展开更多

Moreover, the longer duration of heavy rainfall maintain the higher groundwater table, the shear strength parameters may be decline due to the soil being soaked for longer period of time. The campus of Huafan University is mostly covered by colluviums that located on Mt. Da-Lum, Shih-Tin Hsiang, Taipei County, Taiwan, China. Slope stability is one of the major concerned issues, for this reason, a slope monitoring test site has been established around the campus. According to the data collected, the magnitude of slope movement influenced by rainfall can be observed. In this study, the colluviums samples are collected from the campus of Huafan University and direct shear tests are performed to obtain the shear strength parameters of the remolded soil samples that soaked in the water for various periods of time, i.e. 0, 1, 2, 3, 5 and 7 days respectively. From these tests, the change of the shear strength and slope stability of colluviums with respect to the soaking time of soil has been further understood.展开更多
