Studies Of Theory And Method Of Landscape Planning Of Urban Green Space

Based on the analysis of theoretical research on Planning of Urban Green Space System at home and abroad, this thesis systematically puts forward four basic principles of Green Space Landscape Planning: ecological principle, morphologic principle, culture principle and mentality principle. Green Space Landscape Planning has the service function of ecology, morphology, culture and mentality. The thesis also applies the theory to practices in the construction of expressway Green Space Landscape Planning and planning of Luoyang city green space ecological system .The sciences and art of Planning of Urban Green Space System are mainly evaluated by its conformity to the four basic principles. The coupling and harmonious functions among ecology, morphology, culture and mentality symbolize a perfect Green Space Landscape Planning .The ecological principle shows that only if the separate green patches are connected much closely and a correlative urban green ecological system is constructed, it can play full ecological service function. It also reveals that the effective way to strengthen such function is to proceed from the plan, dissolve special and auxiliary green land parks and constructions, keep the nature and completeness of rivers and mountains, increase the area of ecological ribbon-type green land, and establish an ecological shelterbelt network which is expert in one thing and versatile at many. And the only way to solve ecoenvironmental problems of cities is to give priority to the open space guided by the principle of ecology restoration.Morphology and culture are two important aspects involved in the plan. The beauty of morphology embodies the rationality of space structure and property of scale, proportion, color and rhyme scheme. The culture aspect, representing the collection of particular "place spirit", makes people get sublimation of heart and detachment of spirit when enjoy it. Morphology is culture's carrier, and culture is morphology's soul. The perfect combination of the two aspects forms green land's solace function. The morphology function serves for perfecting city's morphology, creating the comfortable outside activity space which is dotted with green land. The culture function serves for shaping the soul of green space, bearing historical culture, rendering spiritual comfort, promoting culture quality and creating the atmosphere of regional culture.The basic principles of the rational plan of park green are human-oriented principle, comfortable principle, personalized principle, social principle and safe principle. The environmental image with overall character of a region or some historical culture atmosphere is built up by the whole combination and organically connection of a series of continuous and various elements. In view of landscape, the paper analyses the appliance offive elements - path, node, edge, region and landmark - to the Plan. A completeand perfect landscape space should be formed on the rational space design constituted by the five elements. Hence, the features and characters of city and region will be molded.The research into the constructive technology of Green Space Landscape Planning on southwest round expressway of Zhengzhou City shows that the united landscape and ecological shelterbelt networks combining engineering site choice, design, construction and ecological protection can make a rational use of resources, lower the production cost, reduce the pollution to environment and increase integral benefits. It is the effective way to Green Space Landscape Planning construction. A comparative trial mentioned in the paper reveals that in order to prevent soil erosion on highways' side slopes, we should form a multi-shelterbelt of arbor, bush, flower, grass, vine by adopting the international advanced spray-paint technology to rapidly recover the vegetation and other various planting technology.Take the ecological shelterbelt network on the expressway as an example. By applying the "ecology restoration" and "ecological service" theories and methods to practice, we can turn th...
