| With the urban population is dense, green landscape of urban parks is aging, and deterioration of ecological environment, urban green parks have been unable to meet the demand for use of the crowd on the landscape and ecological. How to create a city parks and green spaces in landscape and ecological benefits, have become a hot issue in today’s study. Ecological restoration technology has been the solution of the basic means of sustainable development of the green landscape of the city parks these years. In the city park landscape, ecological restoration technology has been used in a wide range of applications and it must be an inevitable trend by development of the times. But the research of theory and practice about ecological restoration used in the cold city park landscape was few because of regional environmental constraints. So study on landscape construction of green parks in cold city based on ecological restoration technology must be innovative and exploratory.Climatic characteristics of the cold city to control the use of ecological restoration in the city park at home and abroad, and reasonable improvements and technical adjustments, the following conclusions:through the constructed wetland technology, artificial ecosystem floating island and riverbank protection technology to solve cold city water pollution of the landscape and landscape ecological effects, through the grass storage and application of permeable pavement to solve the crisis of urban parks in the rain recycling and the elimination of surface runoff, through planting against pollution trees, aromatic plants and resistance strong plant use to solve the problem of air pollution and soil improvement, plant cultivation by adjusting the direction to guide the wind direction and wind speed decreases, combined with the characteristics of the local monsoon, moderate increase in the fountain and spray, increasing the content of negative oxygen ions in the air, purify the air and improve air quality, Design by rational and effective composting, waste re-use to plants fertilizer, reduced maintenance costs, facilitate management and maintenance of city parks. Through the introduction of each operation process of ecological restoration, the corresponding technical principles and to achieve landscape and ecological effects of base repair technology to extract water environment and ecology, soil ecological restoration, atmospheric ecological restoration, summarized a series of appropriate cold toecological restoration techniques adopted by the city parks, green landscape of the city parks to create a study to lay the theoretical foundation.Finally, Harbin Urban Planning Park, for example, the green landscape planning and design, full use of ecological restoration techniques to control the internal water pollution, soil contamination and air pollution, in order to achieve the perfect combination of theoretical research and case design.Through this thesis, the techniques and methods suitable for the cold city park green landscape design ecological restoration were extracted, and provide valuable theoretical guidance practical reference for creating a beautiful, ecology, sustainable cold city park green landscape. |
