On the Craft of Gardens (Yuanye) and Urban Landscape Design Xiaowei Zhanga, Jingwei Zhaob Shandong University of Science and Technology, Qingdao, Shandong 266510, China azxw1974@sohu.com, bzjwzbt@126.com Keywords: The Craft of Gardens, urban design, landscape, ecology, livable Abstract: Urban human settlement construction advocates paying attention to the simultaneous and coordinated development of urban social production with natural environment in the process of urbanization; facing the many problems in the development and construction of modern cities, this paper discusses deeply on modern urban ecological design connecting with modern urban green design, landscape design and ecological design by studying the design idea reflected in The Craft of Gardens (a Chinese book on gardening by Ji Cheng); it also proposes that the simple ecological view of The Craft of Gardens should be integrated in the concept of modern landscape planning and should be developed and extended, which obviously
‘The ingenuity lies in that it is based on the original form of materials; the fineness lies in that it has the moderate form and appropriate size (qiao yu yin jie, jing zai ti yi)’ and the balance and reasonability of urban landscape design ‘Theory of build and construction’ in The Craft of Gardens emphasizes the idea that ‘the ingenuity lies in that it is based on the original form of materials; the fineness lies in that it has the moderate form and appropriate size’.
That ‘the ingenuity lies in that it is based on the original form of materials’ and that ‘the fineness lies in that it has the moderate form and appropriate size’ mean to borrow land and humanity conditions.

Introduction Silica aerogel is an attractive material in many fields, such as thermal insulation, adsorption, acoustic insulation etc. due to its high porosity (80~97%) and high specific surface area (500~1200m2/g) [1,2].
Commercial expandable polystyrene (EPS) is a traditional insulating material used in exterior insulation, food preservation, and so on for many years as its low thermal conductivity which benefits from the low density and a large number of micrometer/millimeter (μm/mm) closed/open pores[6,7].
