| Incremental greening is a new ways of greening gradually, have novelty, systematization and continuity, it was put forward by green department of Xi'an city in 2004. Incremental greening of green space of main road in Xi'an city is the most important part of the incremental greening in Xi'an city, with self-system and distinguishing characteristics.Incremental greening of green space of main road in Xi'an city bacoming a representative sample of citywide, for it have the important geographical location, involving in a wide range of length, large financial and material resources , strong continuity and other factors.Research incremental greening of green space of main road can find out the mainstream of development of the incremental greening in Xi'an city, imaging the big from the small, and explore the formative process and development tend of incremental greening in Xi'an city.The new ways of incremental greening of green space of main road in Xi'an city is actually through the survey and analysis of green space, purposive proceed to plant again, to the features of the original green space, lack of compensation for the purpose of landscape effects. Specific practices to increase the plant species, number, body posture and the amount of individual plants, increasing stem of plant, color of leaf arrangement to achieve green space of road a substantive leap.The way in the investigation, from the Chinese and foreign history and green space in the function of green space of road, combining the status of Xi'an physical geography, climate and cover plant, comprehensive understanding of the process of green space of road in Xi'an, to lay the foundation for the incremental greening investigation.Green census surveys used the main roads and key sections of observed counts, the process of finishing the formation and development of new applications visits garden plants, plants used in the registration of color, incremental greening impact on the green pest survey and other methods to achieve multi-level, multi-angle three-dimensional green space and time increments investigation. In the Investigation and analysis, the special investigation as a breakthrough, analysis three specific events with emphasis on the application of the new garden plants, colorful plants, and incremental greening impact of pests were analyzed and the nature of incremental greening effect on the landscape, pest occurrence.With incremental greening of main road analysis, focusing on incremental process has already started or not yet discussed the six issues. Increase in the number of trees; expand the tree flowers, ground stress-resistance cover plants applications, application of native tree species, and color-leafed plants, pest suppression into six topics of focus.The results showed that incremental greening of green space of main road in Xi'an city has experienced incremental budding, formation, expansion of three stages.In the process of formation and development to create a flower road, roads and green space to build a harmonious, the streets around the small green square to form a small city garden green frame of three interconnected ways in full swing, the formation of a sound system.On this basis, greening incremental mode has three characteristics: Incremental greening creation of new green model in Xi'an, with a leading level;Incremental greening approach with the characteristics of sustainable development and strong systemicIncremental greening have a good promoting role to the greening of the re-improvement and development.Incremental greening model is worth promoting in the countryThe development of incremental greening of main road in Xi'an city has made some achievements, and has been recognized by multiparty, the development is still more space in the future.Papers from the survey data analysis, combined with the actual green of green space in urban, and put forward proposals for future development, that increase the planning and construction efforts to improve on the special space three-dimensional promotion, planting native trees and perennial flowers, to enhance ecological sustainable development is to expand and improve incremental development of urban main roads and quality of green, all of them are four main directions.Incremental greening of green space of main road in Xi'an city work leading position in the country, and experienced an unusual stages of development, creating a new form of green, will promote the national urban and rural development to a higher urbanization development level of improvement.Incremental greening is a systematic project to improve the urban ecological benefits, especially in the quality of the public environment life important way, is the green landscape ecological environment improvement and optimization of synchronous basic guarantee.Therefore, incremental greening is the development theory of comprehensive theory and practice behaviorof based on systematic subject and modern humanism idea, need more exploration and summary of the future. |
