【摘要】 随着城市人口的密集,城市公园绿地景观的老化,生态环境的恶化,城市公园绿地已无法满足使用人群对景观及生态的需求。如何营造出良好的城市公园绿地景观效果及生态效益,成为当今研究的热点问题。生态修复技术是解决城市公园绿地景观可持续发展的基本手段,在城市公园绿地景观营造中的广泛应用是时代发展的必然趋势,由于地域环境限制,导致生态修复技术在寒地城市公园绿地景观领域中的理论与实践研究成果较少,故“以生态修复技术为基础的寒地城市公园绿地景观营造研究”具有一定的创新性及可探索性。本论文采用理论与案例相结合的研究方法,针对寒地城市气候及植物资源等限制因素,以水污染修复技术,土壤污染修复技术及大气污染修复技术为切入点,力求探索出适宜寒地城市公园绿地景观营造的生态修复技术。在介绍每种生态修复技术的操作流程、相应技术原理及所达到的景观和生态效果基础上,归纳总结国内外公园绿地先进生态修复技术手段,提炼出适宜寒地城市公园的水环境生态修复技术、土壤生态修复技术、大气生态修复技术。具体包括：通过人工湿地技术、人工生态浮岛技术及生态护岸技术解决了寒地城市水体景观的污染及景观生态效果：通过草地储水和透水铺装的应用解决了城市公园中雨水回收再利用及消除地表径流的危机；通过对抗污染树种、芳香植物和抗逆性较强植物的运用,解决了空气污染及土壤改良的问题；通过结合当地季风特点,调整植物种植方向引导风向和减小风速,适量增加喷泉与喷雾,增大空气中负氧离子的含量；通过合理有效的堆肥设计,将废物再利用产生植物的肥料,减少了养护成本,为城市公园管理养护提供方便。最后,以哈尔滨城市规划公园为例,充分运用生态修复技术手段解决公园绿地建设所面临的水污染,土壤污染及大气污染问题,将研究的一系列的生态修复技术手段应用到实践中,以实现理论研究与案例设计的有机结合。通过本论文研究,提炼出一些适宜于寒地城市公园绿地景观营造中的生态修复技术手段和手法,以期为营造出美观、生态、可持续的寒地城市公园绿地景观提供有价值的理论指导与实践参考。更多还原

【Abstract】 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.更多还原
