Study On Three-Dimensional Greening Mode And Technology Of Urban Landscape In North China

Along with the process from agricultural civilization to industrial revolution,the process of human transformation of nature is speeding up gradually,but the urban space environment is being consumed and destroyed,resulting in a series of ecological problems.Therefore,it's very urgent to improve the quality of the environment,to create ecological,livable urban environment,and that cannot be ignored.In this context,three-dimensional greening emerged as the times require,and attracted wide public concern.Three-dimensional greening will also become the most effective measures for city greening in the future.Through literature review,this paper analyzes the research progress and different types of practical results of urban three-dimensional greening both domestic and international,and obtains the effective experience of urban three-dimensional greening design,construction,maintenance management and so on.Compared with foreign countries,the application of three-dimensional greening in domestic cities is still not wide enough.Meanwhile,due to the influence of climate and economy,the development of three-dimensional greening lags behind in northern cities in China.Through the comparative analysis of the cases and the research methods of consulting the theoretical books,this paper summarizes the relevant forms and techniques of the existing three-dimensional greening which has been developed,learns and uses different regions,backgrounds and types of three-dimensional greening examples both domestic and international for reference.Besides,the scope of application pattern of three-dimensional greening in northern cities is re-summarized and classified,and then the paper summarizes the key technologies and measures corresponding to the new technology of building wall greening.Meanwhile,it studies the selection and collocation of the three-dimensional greening plants in the northern cities,and the optimized countermeasures were put forward toprovide scientific and effective professional support for the three-dimensional greening of the northern cities.Finally,this paper takes Tianjin Ecological City Pilot Area as an example,carries on the overall design conception,puts forward the relevant design principles,deeply analyzes the natural resources and historical and cultural resources of Tianjin,integrates the regional characteristics culture into the three-dimensional greening with the natural design method,and carries on the innovative comprehensive design,in order to design a kind of various urban three-dimensional greening scene with the regional characteristics,to serve the current ecological restoration and urban restoration as well as ecological civilization construction.
