| The rapid development of modern economy and the expansion of the urban construction, a series of ecological environment problem occur, such as the fog is increasing serious, sharp shortage of non-renewable resources, and so on. Throughout the life cycle,including design, material, construction, use, recycling, the ecological garden design requirements to save energy, reduce pollution and reduce the use of non-renewable resources as far as possible. Bamboo is recognized as environmentally friendly biomass material not only for its unique renewable, biodegradable, can be repeatedly used and other ecological attribute but also for abundant resources, strength, easy processing and other economic characteristics.Taking bamboo sketch as research object, through the study of bamboo products in the application of the garden, then for the development of the ecological and cultural characteristics of the landscape sketch theory provides a certain reference.In this paper, the results of the study are as follows:(1) Analyze the enhancement of material properties of bamboo, bamboo physical attributes and low carbon environmental protection attributes. Think that bamboo has good physical properties, main performance in mechanical properties (including hardness, strength and flexibility), durability, heat insulation, plasticity, shock resistance, etc.(2) The classification according to the main function of bamboo sketch could be divided into ornamental bamboo sketch, recreation entertainment bamboo sketch, service bamboo sketch and manageability bamboo sketch four categories. Also make an analysis on the application of bamboo sketch place, think that bamboo products in organic gardens, forest park, bamboo culture, the expo garden, garden expo garden etc widely used.(3) Base on the enhancement of application type and application of bamboo place comprehensive investigation and analysis, this paper puts forward the enhancement of design principles of bamboo:scientific and reasonable principle;aesthetic principle; inheritance, innovation principle;and the principle of the four cardinal principles of regional culture. Under the guidance of the four principles, respectively from the material, the space shape, culture express three aspects to study bamboo sketch design. Bamboo sketch on materials used mainly for the original bamboo, bamboo weaving, and bamboo integrated timber, etc. Bamboo sketch modeling space design methods are: combining realism and exaggeration, draw lessons from transplantation, decon-struction reshaping, plane silhouettes, permutation and combination, etc. The enhancement of culture of bamboo can adopt standard expression, scene interpretation and couplets text dot eyeball, real experience, symbol extraction technique such as symbol, metaphor, image convey to express.(4) Through the design of actual case, applying the results to the specific project, the realization of bamboo products in the application of the garden design. Take phoenix mountain forest park "xiangshan bamboo sea" scenic area as an example, the design of the ornamental, recreation entertainment, service and administrative four types of bamboo,10 nodes on bamboo design sketch expression in the park.(5) The application of bamboo in the process of corrosion, insect-resistant, crack, dehydration treatment and the enhancement of protection and maintenance method of bamboo sketch are proposed. |
