Investigation And Study On The Application Of Stereoscopic Greening And Landscape Evaluation Of Urban Comprehensive Parks In Qingdao

In recent years,my country’s urbanization has developed rapidly,and rapid urbanization has triggered a rapid increase in the urban population,resulting in an imbalance in the urban green space structure,which has a significant adverse impact on the urban ecosystem.Urban environmental problems such as flooding of urban rain,urban smog,reduction of biodiversity,heat island effect and other urban environmental problems continue to appear,and even the trend of global warming is increasing day by day.The process of urbanization continues.The shortage of urban land resources has become an important factor restricting the balance of land use in three living spaces(living space,production space and ecological space),while the shortage of ecological land space has become a restrictive factor hindering the healthy development of urbanization.Therefore,urban development changes from incremental development to stock optimization development,especially under the background of limited utilization of urban green space,stock optimization of urban green space is an important strategy to optimize urban environment and maintain urban ecosystem health.The three-dimensional greening form is an important means of urban greening construction in the stock optimization and promotion.The surface space of buildings(structures)in urban space can be constructed by three-dimensional greening,which can transform two-dimensional green space into three-dimensional green space.It is a space resource that can not be ignored in the process of urban green space expansion.Practice has proved that three-dimensional greening has the advantages of less land occupation,fast effect and high greening rate.Some studies have shown that three-dimensional greening has significant effect in improving urban heat island effect,alleviating urban rain and flood,reducing air pollution and improving urban biodiversity.Therefore,three-dimensional greening has become an important means to increase urban green area and solve urban ecological problems under the background of high urbanization.Due to the significant comprehensive benefits of three-dimensional greening and the vigorous promotion of policies,three-dimensional greening has become one of the important means of urban greening construction.However,in the whole life cycle of planning,design,construction and maintenance,traditional three-dimensional greening often has a series of practical problems,such as simple application form,single plant species,poor landscape effect and high maintenance cost.In view of some practical problems of three-dimensional greening,there are many researches and explorations at home and abroad,such as special planning of urban three-dimensional greening,multi-objective oriented three-dimensional greening planning and design of landscape improvement,biodiversity improvement,microclimate improvement,etc.Therefore,it is of great practical significance to find out the practical problems of three-dimensional greening construction through investigation and put forward scientific and reasonable solutions by using subject knowledge.Based on the scientific definition of three-dimensional greening in urban construction,taking Qingdao City as an example,this thesis selects three-dimensional greening of urban comprehensive park as the research object,and investigates the planning and design,plant application and other aspects of three-dimensional greening.This thesis takes the three-dimensional greening of Qingdao comprehensive park as the research object,finds the practical problems existing in the construction of three-dimensional greening of Qingdao comprehensive park through field investigation,and puts forward the corresponding optimization strategies through the analysis of excellent practical cases and theoretical research results at home and abroad.At the same time,the main problems in the application of plants in the construction of three-dimensional greening are analyzed and summarized.Through the selection principle of three-dimensional greening plants,the recommended list of three-dimensional greening plants in Qingdao comprehensive park is put forward.The purpose is to make the three-dimensional greening more efficient in improving the quality of urban environment,improving the level of urban greening,ecological environment and landscape effect,and better reflect the characteristics of urban development.
