Evaluation Of Soil And Greening Condition In Xingnan Area Of ​​Daqing Oil Production

Urban greening is a symbol of urban civilization and development, to improve urban ecological environment, improve the urban living environment quality, and perfect urban landscape design, can not be separated from the reasonable distribution plant, and a rich variety of plant material. Soil plays crucial role in the functions of urban green space in the soil affects urban residential suitability, the quality of the environment and people’s quality of life, urban landscape is inseparable from the soil in the garden city, the status of soil quality is directly related to the growth condition of landscaping tree species. In this paper, the soil of the fifth Daqing oil production plant landscape physicochemical properties were tested and analyzed, and comprehensive evaluation of the soil fertility status, reveals the main problems existing in the fifth Daqing oil production factory of Greenland soil; in addition, fifth Daqing oil production plant landscape of the application of arbor, shrub, paving and other landscaping tree species, growth performance, application forms and application effect of on-the-spot investigation, and comprehensive analysis and evaluation of the result of the investigation. Urban soil conditions and the investigation of greening tree species can for landscape design to provide material makes the urban landscape design more standardized, rationalized, urban greening tree species selection provides scientific basis and realize the sustainable development of the urban landscape construction.The survey showed that: 1, Daqing oil production five plant landscaping of the soil condition: through the 54 point of the determination of the main indicators of the soil clustering analysis, and combined with the field observation of classification. Results there are 25 points for severe saline alkali, accounting for 46.3%; there are 17 points for the moderate salinity, accounting for 33.5%; 12 points for the mild saline alkali, accounting for 22.2%. The 12 degree in plant and soil sampling for soil ecological park. The five plant soil salinization is serious, which is the main factor that restricts the development of afforestation. 2, green tree species application:(1) the five factory of Daqing oil production and application of landscaping tree species in 15 families, 31 genera, 37 species;(2) the geographical composition of species flora greening mainly temperate, subarctic and has certain composition;(3) the application status of landscape trees Joe shrubs: wood floor: class ratio of 17:18:2;(4) the growth of tree species survey found application and greening tree species in Daqing oil five plants species: general growth situation is better, because the soil condition of the plant area belongs to the deviation region in the Daqing region, recommend choose native and resistant species, to green to beautify, according to local conditions; instead, will cause adverse consequences, such as ecological garden planted birch and SA on the Boulevard clove almost all died, is improper.From the above analysis combined results of the survey records and found serious overall salinization Daqing oil Wuchang Wuchang soil, rich enough presence on Species and Species application is not reasonable, conservation management is not in place and other issues landscaping trees applications; solve these problems propose to do landscaping trees planning, attention to suitable tree principle, improve landscape conservation management level development. In Daqing oil Wuchang landscape trees and shrubs application investigation and analysis based on the combination Daqing oil Wuchang garden trends and laws of natural vegetation, environmental conditions, administrative division, and other characteristics of Daqing oil Wuchang City ecological park vegetation and landscape restoration rehabilitation programs and propose recommendations. Daqing provide urban green space construction and further development of the information and the scientific basis of the urban landscape construction character, provide realistic theoretical basis for the Daqing oil Wuchang Landscape Species Selection and nursery production.
