| In 1972,the concept of Sustainable Development had been proposed in the Human Environment conferences by United Nations which became a consensus all over the world.In 1993,the American Society of Landscape Architects published the "Ash Declaration on Environment and Development" and proposed the concept of "Sustainable Landscape".Since then,the theory of sustainable landscape had been widely used in landscape design.Based the study on these,the thought of Sightseeing Agricultural Garden was emerged.Recently,sightseeing agricultural garden developed very fast.It based on the natural environment and the attraction of sightseeing and agricultural experience which promotes rural economic development,increases the income of farmers,and becomes a booster of rural area's development.However,the rapid development of sightseeing agriculture garden has also brought some problems, such as the destruction of the natural environment,urbanization of landscape,the loss of the rural characteristics,the lack of system considerations,which has seriously hindered the development of sightseeing agricultural garden.Although more and more managers of sightseeing agricultural garden became to pay attention to the "ecology",and labeled their garden ecology,but most are only a mere formality.The real "eco-agriculture sightseeing garden" is based on the protection and rational use of natural resources,and then plans the functional layout,system structure,operation and management coordinately which can formed the sustainable development model.Planning and designing is very important for the eco-sightseeing agricultural garden's sustainable development.At present,the theory of eco-sightseeing agricultural garden's planning and design hasn't form a system.Based on the experience of sustainable landscape,ecological landscape theory and garden plan theory,using the method of"Layer cake method" by Ian McHarg.This method divided the landscape into 6 layers,such as water layer,terrain layer,traffic layer,architecture layer,plants(not include agricultural plants) layer and agricultural system layer.Through the research of each layer, which summed up to the sustainable planning and designing method of eco-sightseeing agricultural garden. |
