Optimization On Urban Green Open Space Of Shangqiu By The Objective And Subjective Cognitive

With the rapid industrialization of the world, urbanization and modernization, which promote social progress and economic development, urban construction continues to accelerate, causing such a large population, resource shortages, environmental vulnerability and other aspects of various pressures, and the city increasing the density within the external boundaries continue to expand, and continuously occupied the "green open space" on the urban environment with serious impact. Urban green open space as an important natural urban landscape for cable, not only has the landscape, ecological, aesthetic and other multiplier effect, more direct impact on urban development, environment and quality of life of residents, the establishment of an eco-green open space network structure, expanding the scope of the natural habitat areas, maintaining biodiversity, improve environmental quality of the earth, so that urban tissue and the organic integration of natural elements, creating a financial form of urban space in nature, no doubt have a distinct and significant features of the times practical significance.Shangqiu in Henan Province, the eastern, known as "Yudong portal," said, Henan implementation of "east to the west," the bridgehead in the revitalization of Central China Henan occupies a very important position. In order to "Yudong portal" stand tall and straight, intensified investment in recent years, rapid urban development, urbanization has entered a rapid and complex stage of development, Shangqiu has undergone enormous changes, but also facing the population, resources, energy , environmental, social harmony and many other issues the challenge, coupled with the greening level Shangqiu itself has been relatively low, its rapid development to the environment caused a lot of pressure, so the layout of green space in Shangqiu to more and more attention, the author is based on the the context of types of urban green open space proposed Shangqiu subjective and objective cognitive and optimization. This article by asking questions, analyzing and solving problems the idea of arranged main content. The main contents are as follows:First, the background under the proposed Urban Development Shangqiu the need for optimization of green open spaces, green open space from the analysis of the basic methods and theories start Shangqiu built-up area of green open space of the current situation and the subjective perception of objective analysis of entities, thus making evaluate and identify the causes of the problems and propose specific optimization schemePaper is divided into six parts, four blocks, namely, an overview of theoretical research articles, case studies chapter, summing up.First chapter, describes the problem of urbanization and ecological background, proposed to the city through the construction of green open space and reasonable layout of the city's environmental quality improvement, indicating the purpose and significance of research ideas and techniques described route, and that of the theoretical basis used in and the methods and techniques.Second chapter, by defining the concept of urban green open space to explain the meaning of urban green open space and research. Green open space at home and abroad to do research and present historical review summarized, and research perspective for summarization.Third chapter,define the scope of the study area, in the research area of green open space, based on the physical status of an objective analysis of existing problems.Fourth chapter, by conducting a questionnaire survey of green open space in Shangqiu subjective perceptions of the current situation.Fifth chapter, Find out of shangqiu city green open space the problems and reasons, discusses the optimization principle of green open space, optimizing targets, as a basis for optimizing the respectively on green open space space composition, elements two parts optimized design research.Sixth chapter, Conclusion. The main content of this article, innovation and a summary of the inadequacies to be future perfect.Paper the following conclusions:First, in the collection of a large number of green open space on the status of Shangqiu basis of the information, technology based on ArcMap, AutoCAD, Photoshop software to complete Shangqiu Analysis of urban green open space visualization of the study area of green open space of objective knowledge available: green open spaces of most Shangqiu level of garden design is better, but the small number of uneven distribution, characteristics and cultural connotations are not fully excavated, without considering more entertainment features such as recreation; green space in the overall production of green fragmented distribution, plant community structure is simple, nursery construction quality is not satisfactory, the quality and landscape protection on the green from the city can not meet the needs of high pressure around the corridors and industrial areas do not form an effective shelter belt. The performance of the subsidiary for the overall development of the imbalance in green; water quantity and distribution of good, but water quality deterioration, poor water management chaos.Second, by sampling survey Shangqiu urban residents, rely on SPSS software, technical analysis of survey data on the status of Shangqiu green open space available for subjective perception: the overall urban green space on the status of Shangqiu, a large comprehensive park, evaluation of community parks and green space is better for the overall quality and quantity of green space, the space distribution status, roadside parks, gardens evaluation unit general; on the ecological environment, air quality, noise, river water combined assessment of heritage conservation areas lower ; residents demand arrangement of the major plant communities are structured, arbor, shrub and grass scattered with good three-dimensional landscape ecology, focusing on the development of urban centers of point and linear green space, the development of community parks, marinas and so close to people's daily life green, and integration of a long cultural history Shangqiu.Third, in the evaluation, through the cognitive and subjective perception of objective findings to overlay analysis to identify the problem Shangqiu green open space and causes of the problem. Analysis and evaluation based on the results of green open space in Shangqiu Spatial Structure (outer circle, the main circle, inside circle), elements (gardens, green spaces, water bodies) were optimized. Taking Shangqiu City Master Plan 2005-2020, the city maps as the basis, in the near future on the basis of the overall plan of green open space used Shangqiu AutoCAD, Photoshop, CorelDraw, and other software to complete the optimum design visualization.
