Study On Planting Optimization Design Of Urban Ground Parking Lots

With the rapid development of urbanization in our country and the background of the automobile age,people's demand for parking spaces is increasing day by day,and the scale of urban parking facilities is gradually expanding.As a part of the urban parking facilities,the ground parking lot has not been improved while the area occupied by the site and the number of parking spaces have increased.the urban builders have not paid enough attention to the ground parking lot.therefore,aiming at the common environmental problems in the urban ground parking lot,this paper hopes to optimize and improve the plant planting method of the parking lot through scientific simulation calculation,and achieve the research purpose of improving the field environmental problems to the greatest extent by using the limited green planting conditions of the site while ensuring the occupancy of the parking space.Firstly,this paper introduces the existing greening planting standards and methods in parking lots,analyzes the current general situation of urban ground parking lot greening,points out the reasons why parking lot greening is less and greening is difficult,and leads to the research content of improving urban ground parking lot and optimizing site planting.The basic research also includes a brief introduction to sunshine calculation software,fluid simulation software and important modules.In the specific research content of planting optimization design,the article begins with the contradiction between parking space occupancy and green land,studies the possibility of integrating parking space design with green planting design,and makes a detailed analysis of the relevant knowledge and specifications involved and discusses the optimization methods.Then,regarding the high temperature environment caused by the insolation in summer in the city's ground parking lot,the possibility of improving the site's thermal environment by reasonably arranging shading plants,maximizing the natural shading function of plants,and increasing the effective shading area is discussed.In the study aimed at improving the wind environment of urban ground parking lots,the effects of plant morphology,plant planting form,plant layout design and deepening design of parking lot planting on the wind environment of the sites were simulated and analyzed.The last part of the third chapter combines the rainwater pollution problem of the urban ground parking lot to improve the rainwater treatment capacity of the green space of the site.After a large number of analysis,discussion and simulation studies have been completed,in chapter 4,the article sorts out the existing research results on increasing parking space occupancy,increasing shading coverage,improving wind environment and rainwater treatment capacity,and further discusses and verifies the optimization of parking lot planting design methods.Finally,according to the demand for multiple characteristics of the same plant in the parking lot planting design,according to the mathematical method of weight coefficient and weight calculation,a plant comprehensive evaluation method for optimizing the plant planting in the parking lot is proposed.
