Landscape characteristic aesthetic structure: Construction of urban landscape characteristic time-spatial pattern based on aesthetic subjects

The paper presents means and models of city-landscape characteristic structure construction on the aspect of landscape aesthetics subjects, which is called the landscape characteristic aesthetic structure and in short as LCAS. In this paper, the steps of LCAS research are as follows:Describes the concepts of the landscape characteristic aesthetic structure (LCAS), and expounds the LCAS properties: systematic quality, temporal and spatial quality, and virtual existence.Learns from typology research methods, discusses the elements and types needed in a landscape characteristic aesthetic system, and constructs research method for LCAS pattern. As for the temporal dimension, the dynamic evolution and interaction expressed in LCAS between the “tradition” and “modernity” landscapes conflict. As for the spatial dimension, this paper explores the LCAS patterns in macroscopic scope of city group, the middle scope of single cities and the microcosmic scope of urban spaces with questionnaires and examples research.Uses pattern language to express different LCAS types in the temporal and spatial system.We develop the patterns of various LCAS types with graphical patterned representation, as well as construct the LCAS research method and theory which is based on the general people's aesthetic standards and sensibilities to build city characteristics and urban landscapes as a guidance.
