| Garden green space is an important part of urban construction,and the embodiment of the overall image of the city,which has many functions such as environmental beautification and ecological protection.As the gate of the city’s image,the airport’s greening level shows the urban development and local characteristics.The key to maintain a clean and beautiful green landscape lies in high-quality maintenance and management,but there are many requirements for airport security,which has certain challenges for the efficient maintenance and management of airport green space.Xi’an Xianyang International Airport,as the largest transportation hub in the northwest,represents the image of the northwest,but its green landscape effect is average,and there is a gap between the growth of plants and the growth requirements that plants should meet under high-quality maintenance standards.In addition,there are some problems in the maintenance and management of airport green space,which have an important impact on the maintenance and management effect,and then affect the green landscape effect of the airport.In this paper,the general situation of natural conditions and the present situation of green space maintenance and management of Xi’an Xianyang International Airport were investigated and analyzed,and the plant species in key maintenance areas and the existing problems of airport maintenance and management were clarified.On this basis,the growth of plants was analyzed according to the quality standards of garden green space maintenance and management.The plants with poor growth in key conservation areas were studied,and the relevant test results can provide reference for the subsequent maintenance and management of the airport.The main results are as follows:(1)The green space(area: 43,342 m~2)in the experimental area recorded 30 species of plants,belonging to 17 families and 26 genera.Among them,there are 13 species of large trees,7 species of small trees and 10 species of herbs;There are more plants with constant color leaves and fewer plants with color leaves.(2)According to the growth habits of garden plants,environmental conditions,and the reference quality standards of various levels of green space,the growth of plants was analyzed,and the reasons for the poor growth of specific plants and poor landscape effect were clarified.It points out the direction for the follow-up experimental research.Based on the in-depth analysis of the maintenance and management of airport garden green space,it is clear that there are some problems such as imperfect maintenance management system,disjointed construction and maintenance,low comprehensive quality of maintenance management team and low modern technical level of maintenance management,etc.,and reasonable suggestions are put forward to provide reference for the maintenance and management of airport garden and landscape department.(3)The experiment of improving soil conditions by applying fertilizer to three plants,namely,Osmanthus fragrans,Photinia × fraseri and lawn,and applying carbon-based nutrient fertilizer to greening maintenance showed that the soil pH under carbon-based nutrient fertilizer treatment was closer to the suitable pH value of plants for different plants,which effectively improved the nutrient content in the soil,and had a more significant improvement effect on plant growth compared with the conventional maintenance mode in the airport,reducing the occurrence of pests and diseases and the consumption of nutrients at flowering stage. |
