Application Research Of Landscape Woody Plants In Tianshui

With the development of modern industry, business, science and technology, socialstructure is updated ceaselessly. The continuous expansion of city scale, city populationdensity, the natural environment has been destroyed, the original green gradually occupied isbeing occupied, the more pronounced contradiction between human and nature, and landscapewoody plants used as the most important part of urban construction is more and moreattention by people. This masters thesis takes the landscape woody plants as the object ofstudy in Tianshui, conducted a field investigation of Tianshui public green space, residentialgreen space, road river green space, attached green space, green production, protection greenland, scenic forest of seven types of green space, based on the investigation in the fieldthrough the statistics and analysis of the room, we draw the following conclusions:1.139species of cultivated landscape woody pants in tianshui, belonging to48families,87genera. Among them,87species of trees, belonging to33families,51genus;46species ofshrubs,belonging to21families,38genus;6species of vines, belonging to five families, sixgenus.28species of evergreen plants, belonging to12families,18genus;111speciesdeciduous plants, belonging to41families,72genus.11species of ornamental stems,belonging to10families,11genus;36species of ornamental foliage, belonging to23families,31genus;47species of ornamental flower, belonging to21families,32genus;34species ofornamental fruit, belonging to17families,25genus.38species of Spring flowers, belongingto11families,20genus;8species of summer flowers, belonging to eight families, eightgenus;6species of autumn flowers, belonging to six families, six genus; Only two speciesof winter flowers, belonging to two families, two genus, Native tree species in a total of80species, belonging to34families,59genera,11species of Evergreen Group, belonging to6families,9genera; deciduous69species, belonging to31families,52genera.2.Analyse and summarize the appropriate application of Tianshui, cultivation of highvalue and ornamental landscape woody pants115species. Among them,17species of theevergreen trees,55species of deciduous trees and9species of evergreen shrubs,31speciesof deciduous shrubs, three species of lianas.3.Analyse the application of landscape woody plants problems in Tianshui City:(1) Thelandscape woody plants structure is unreasonable, poor stability;(2) A single tree species and poor winter landscape;(3) The lack of local tree species application, local characteristics isnot prominent;(4) The low level of management, maintenance, plant diseases and insect pestsis more serious. For further Tianshui landscaping work, in the future should pay attention toseveral aspects:(1) Strengthening the planning and design of landscape green space system,the relationship between landscape woody plants effect and ecological benefits.(2) The nativetree species as the main body, actively introduce foreign species, seriously big treestransplanting;(3) Strengthen existing landscape woody plants maintenance and management,minimize the harm of diseases and pests, to fully demonstrate their ecological and landscapeeffect;(4) Pay attention to landscape woody plants germplasm resources, domesticatedphased mining high ornamental value and good ecological benefits of wild plantsThis study will provide scientific basis for reasonable application of landscape woodyplants in Tianshui, and for the establishment of the landscape green space system with perfectfunction reference, therefore, improve the ecological environment of landscape city ofTianshui to create sustainable development has important theoretical and practicalsignificance.
