| Road greening is an important part of modern city,it is the important function of urban landscape transportation,and it is an essential infrastructure for modern city.Modern urban greening design,in order to meet the traffic and other road use functions,do a good job of landscape node beautification.It can play an important role in building livable cities and garden cities,such as preventing glare,alleviating driving fatigue,regulating mood and stabilizing emotions,alleviating the urban heat island effect,improving the urban ecological environment,and improving the level of urban greening plants.At china,because the national economy is in the stage of development,the greenery of the flower landscape has not been widely used.In recent years,Guangzhou Huajing has begun to be partially applied to urban roads,street green areas,park scenic spots,green belts,and other pilot applications,and has achieved good results.Combining with the vigorous construction of urban green space,the application of flower space has also been greatly developed.The visual viewing effects generated by the use of flower space on both sides of the city’s main roads and parks are obvious,and the level is clear and reasonable,making tourists pleasing to the eyes and improving the green level.Although the application of flowers in China has been relatively late,it has greatly improved in recent years,which has promoted the development of flowers in China and played an important role in improving the urban landscape effect and improving the green market and ecological efficiency of the cities in which they live.It has become a bright spot and a bright spot for urban greening,but from the current situation,there is a certain gap between the overall level of flower application and the foreign countries in terms of flower materials and types of application.One of the main reasons is that there are still few good plant varieties that can be used in flowers in China.This paper investigates the perennial flower and flower scene arrangement of important road nodes in Guangzhou city.It is objective and realistic to obtain the application and configuration of perennial flower and flower area arrangement of important road nodes in Guangzhou to analyze the species and application of flower flower mirror plant resources in Guangzhou.Therefore,it extends to the application of landscaping flowers and flower environment layout in various districts of Guangzhou and the Pearl River Delta region;Through the analysis and ranking of AHP,to select the best varieties of garden plants that are suitable for flower and landscape arrangement in Guangzhou,and put forward suggestions for the future development of plant varieties for landscape greening in various districts of Guangzhou and the Pearl River Delta region.It provides a reference for the reasonable selection of flower endoscope plants.The following results are obtained after the investigation:(1)There are a total of 22 families and 41 genera of common flower arrangement plants in Guangzhou,and a total of 48 families and 103 genera of flower arrangement plants.Among them,flower plants are red,yellow,pink white,and blue-purple.There are21 families and 26 genera of red flower varieties,16 families and 17 genera of yellow flower varieties,and 13 families and 15 genera of pink and white flower varieties.There are16 families and 17 genera of blue-purple flower varieties.The plant species in the flower area include garden plants such as flowering shrubs,leaf plants,grasses,and various kinds of grass flowers.There are 8 families and 10 genera of flowering shrubs,16 families and 19 genera of leaf plant varieties,and 6 families and 8 species of grass plant varieties.genus,There are 30 families and 35 genera of grass varieties.(2)In the selection system of flowers and flower landscape arrangement plants through AHP,the weight of biological characteristics of 41 flower plants and 103 flower landscape plants was 0.429,accounting for 42.9 % of the weight,which is an important indicator.The weight of landscape effects was 0.429.This represents 42.9 per cent of the weight,which is an important indicator,and 0.142,or 14.2 per cent,of the weight of conservation management,indicating that this indicator is of the least importance.From the result of weight value,the biological characteristics of flower plants are the same as the weight of landscape effect,and the weight of conservation management is low.It shows that the evaluation participants generally believe that the selection of flowers and plants is mainly based on the biological characteristics of the plants and combined with their landscape effects.Secondly,the characteristics of conservation and management of the species need to be taken into account after determining the intended species.(3)Through the AHP plant selection system for flowers and flower areas,the secondary index of 41 flower plants and 103 flower plants,and the comprehensive weight value of the landscape effect of the planting plant is 0.357,accounting for 35.7 % of the comprehensive weight,which is an important indicator;The comprehensive weight value of color color is 0.248,accounting for 24.8 % of the comprehensive weight,which is an important indicator;The comprehensive weight value of flowering period is 0.102,accounting for 10.2 % of the comprehensive weight,which is a secondary indicator;The combined market supply weight value is 0.09,accounting for 9 % of the combined weight,which is a secondary indicator;The comprehensive weight value of single planting landscape effect is 0.072,accounting for 7.2 % of the comprehensive weight,which is a secondary indicator;The combined weight value of flower leaf type is 0.052,accounting for 5.2 % of the comprehensive weight,which is a secondary indicator;The combined weight value of conservation costs is 0.037,accounting for 3.7 % of the combined weight,which is an unimportant indicator;The comprehensive weight value of growth speed was0.027,accounting for 2.7 % of the comprehensive weight,which was an unimportant indicator.The comprehensive weight value of water fertilizer is 0.015,accounting for 1.5 %of the comprehensive weight,which is an unimportant indicator.Judging from the evaluation results,the general critics believe that the landscape effect of plant planting and flower leaf color are important indicators for evaluating flower plants.The flowering period,the plant market supply of single plant planting landscape effects,flower leaf type side as the secondary index to evaluate flowers,flowers and plants,plant conservation costs,growth speed are basically not considered as evaluation indicators.(4)After the comprehensive evaluation of the selection system for perennial flowers and flora in important road nodes in the urban area of Guangzhou,most of the species with high weight comprehensive evaluation are consistent with the actual investigation and application situation,indicating that the results of the selection system are consistent with the actual application situation.The weight of plant varieties and related selection and restriction indexes selected from the selection system of perennial flowers and flower site arrangement of important road nodes in Guangzhou city is of practical significance,and has reference to the selection and introduction of future flowers and flower areas. |
