Study On The Planning And Design Of Conservation-oriented Landscape And Green Space In The Semi-arid Region Of Northwest China

The construction of garden and green space in the process of urban development plays a vital role in improving the urban environment and improving the quality of urban life.However,with the rapid expansion of urbanization and the urban population's demand for land,China's urban green area is becoming less and less,which leads to a series of environmental problems and resource problems in the process of urban development.In the current development of garden green space,with the concept of energy-saving garden green space,many cities in the construction of urban greening,it will be the urban green construction guidelines.However,at present,many designs do not incorporate energy-saving elements.Northwest semi-arid region landscape green space as the research object,from set out actually,for the northwest semi-arid areas of water shortages,lack of green land in city,fragile ecological environment and soil erosion characteristics of the semi-arid region in northwest landscape green space of the existing problems and put forward the corresponding solution measures,in order to semi-arid regions of northwest landscape green space construction and development to provide theoretical basis and practical experience.In this paper,by using the theory of literature analysis,survey method,case analysis and sum up method,combining the theory of landscape ecology,landscape aesthetics,landscape and garden design,urban landscape green space planning,landscape plant cultivation and so on,to the northwest semiarid region landscape green space planning and design in theory research and case analysis,the results are as follows:(1)In the semi-arid region of northwest China,energy-saving landscape design should be carried out from the aspects of rainwater utilization,water-saving irrigation,water conservation technology and cold-resistant plants,so as to comprehensively improve the level of energy-saving landscape construction.(2)Taking Lanzhou's garden green space as the research object,this paper selects several aspects such as water resources,plant landscape configuration management and the coordination between greening and the surrounding environment,and analyzes and summarizes the existing problems in the process of landscape design in this region.(3)Through the analysis of this paper,specific design methods and strategies are proposed from the aspects of water resource conservation,plant allocation,conservation and management,greening and the coordination of the surrounding environment.Finally,it provides certain reference value and practical experience for building a comfortable,environment-friendly,water-saving,energy-saving and sustainable green home with beautiful environment and distinctive features.
