Investigation And Planning Of Urban Landscaping Greening Trees Species Of Hebei Province

Urban landscape can improve the city's ecological environment, enhance the environmental quality, and beautify the city life. Perfect urban landscape design without rich variety of plant materials and reasonable plant configuration, urban landscaping greening trees species survey of urban landscape can provide rich plant materials for urban greening design, and provide scientific basis for urban greening tree species selection, realize the sustainable development of urban landscape construction . Hebei urban landscape undertakings have developed rapidly, and landscaping greening trees species is more and more abundant, but due to a lack of ornamental species planning, there are some problems yet, such as monotone greening form, unreasonable application for tree species using. Through to the field investigation for the tree species, growth performance, application form and application effect for the application of trees and shrubs, vine, woody by ornamental species of urban green space in Hebei province, and comprehensive analysis of the survey results and evaluation, Drawn: (1) There are 38 families, 70 genera, 105 species of current trees for urban landscaping greening tree species in Hebei province; (2) landscaping greening trees species in floristic geographic composition, and mainly temperate distribution with certain tropical composition; (3) the present situation of the application of landscaping greening trees species for 1:0.72, liana species species using proportion than 4.8%, evergreen leaves for 1:3. 91, colored tree species using ratio for 23.3%, indigenous tree species using ratio for 34.3%.(4) evaluation of landscaping greening trees species in Hebei Province reached: the growth of trees in general is good, not cold species poor or cold, in the city of Zhangjiakou and Chengde poor performance, not salinity species in Cangzhou and Hengshui City, and poor performance. In the same city, the native species trees situation is better than the introduction , parks green space and campus have the best growth of the whole ; green space and green residential area somewhat less than individual. (5) by the above analysis results combined with records of urban landscaping greening trees species in Hebei province, found there tree species using is not rich, insufficient place characteristic performance, afforestation form is drab, tree species using unreasonable, maintenance management work does not reach the designated position; (6) in view of the above question offered to do landscaping greening trees species planning, strengthening introduction and domestication of new greening tree species, ascending plant configuration art level, pay attention to tree species selection follow selection in line with principle, improve afforestation tree development countermeasure maintenance management level, etc. (7)Based on the investigation and analysis in Hebei province urban landscaping greening trees species application combined with the characteristics such as the development trend natural vegetation garden law, environmental conditions and administrative districts of urban garden greening in Hebei province, and divided the urban landscaping greening trees species into Hebei north, central Hebei, JiNan area, the exhausted areas of four regions in Hebei province, and according to the regional urban characteristics, planed urban fundamental key trees, key trees and general trees of each zoning area of Hebei province.Providing information and scientific basis for the construction of the urban green space and further development of Hebei province, make the characteristic for urban garden greening construction, and render realistic theoretical references.for Hebei landscaping greening trees species selection and industrialized production.
