This study is based on the research methods of plant resources to investigate the greening plants of streets,residential quarters,parks and squares,the ornamental plants of 569 households selected randomly in Holingola,among which 507 households cultivated ornamental plants and also analyzed their application status.The results are as follows:1.As can be seen from the survey results,there are 63 species(including the variants,below)of greening plants in the urban area of Holingola,which belong to 25 families and 51 genera,among which Rosaceae has the most species and the most extensive planting area.From the composition of life type,there are 23 kinds of trees,17 kinds of shrubs,22 kinds of perennial and annual herbs,and only one kind of fleshy herbs.It can be seen that the life type composition of greening plants is dominated by trees.There are 134 species(including the variants,below)of indoor potted ornamental plants in Holingola belonging to 55 families and 104 genera,mainly distributed in Cactaceae,Liliaceae and Areceae.From the composition of life type,69 species are herbaceous plants,61 species are woody plants and 4 species are lianas.2.According to the classification of ornamental parts,the greening tree species in Holingola can be divided into flowering plant,foliage plant,fruit-effect plants and posture plant.Of the 63 species of urban greening plants,there are 40 species of flowering plants,34 species of foliage plants,9 species of fruit-effect plants,36 species of posture plants.There are 20 species with one ornamental effect,28 species with two ornamental effects,and 15 species with three or more ornamental effects.Because the species of planted trees and shrubs are relatively single,and the species of herbaceous plants are abundant,there are more flowering plants,less posture and fruit-effect plants.Of the 134 species of indoorpotted ornamental plants,there are 57 species of flowering plants,99 species of foliage plants,7 species of fruit-effect plants,14 species of stem plants.There are 80 species with one ornamental effect,and 54 species with two ornamental effects.3.From the composition of the origin of urban greening plants,there are 48 species of plants originating in China.There are 10 plants of American origin.The origin of indoor ornamental plants is mostly from Asia,America and Africa.There are 57 plants of Asian origin,48 plants of American origin and 33 plants of African origin.4.There is an unbalanced development in the greening of streets and residential communities in the old and new districts of Holingola city.The species richness of green plants is not enough,which is in the primary stage of urban green development and has great development potential.5.The roads in the old city areas and the old residential areas have a monotonous variety of greenery,and there are fewer kinds of shrubs and herbs.All kinds of green space reuse the same green plants,lack of characteristics.The number and species of native plants are also relatively small.In general,all kinds of green spaces in Holingola have a large space for development.6.The environmental protection effect of 52 kinds of urban greening plants in Holingola is obvious.It can absorb harmful gas,purify air,reduce noise,purify sewage,improve microclimate,conserve water,keep soil and water,purify soil and prevent disaster.7.Compared with the other four residential areas,the number of ornamental plants in the lianzu fang residential area and binhe huating residential area is quite different,and the number of ornamental plants in these four communities is very close.The Epipremnum aureum appeared the most in the three residential areas.8.According to the survey of 569 households in Holingola,the popularity rate of indoor potted ornamental plants in Holingola was89.10%.There are 9 species of indoor potted plants with frequency over10%,which are Epipremnum aureum,Pachira macrocarpa,Sansevieria trifasciata,Clivia miniata,Kalanchoe blossfeldiana,Chlorophytum comosum,Aloe vera,Bougainvillea glabra and Zygocactus truncactus.Most of these potted plants have strong adaptability and easy cultivation management.Residents in the 31-40 age group planted the least potted plants indoors,the 51-60 age group has the largest number and variety of potted ornamental plants planted indoors.9.The application and investigation results of urban greening plants and indoor potted ornamental plants in Holingola were studied and analyzed,and the selection of greening plants in Holingola was grasped as a whole,which can provide suggestions and references for the construction of greening plants to be more rational,standardized,scientific and characteristic.
