GIS-Based Researches On Landscape Attraction Of Urban Public Park

The urban public park land is a significant component of the urban land, a subsystem of the urban ecological system, an essential physical environment of space to maintain people's life in the urban area. It plays an important role in improving the urban environment, bettering people's life and shaping the city's image, and so on.At present, the research on landscape attraction of urban park is limited to qualitative scale, but has no regular method of calculation. Through MAPGIS software of geographical information system, this paper adopts attraction theory and takes Qingcheng Park, a typical park for municipal service, as an example. It also sets up attraction models and does research on landscape attraction of urban park.This paper is the first to illustrate the six factors which affect attraction, and to decide their importance respectively by Delphi method.It divides these factors into different standards according to their various influence; It states the division standard of the influential factors and their importance; Also, based on these, it poses a method to calculate the influence of attraction Index。Based on"First-bird"image, it takes QingCheng Park for an example, count the necessary data of the population, roads and green land inside the second ring of Hohhot and calculates this data in the model of the influence of attraction Index,and finally gets the attraction index distribution of QingCheng Park. It confirms its evaluation standard, illustrates the attraction grades in figures and gets space distributions of the attraction of QingCheng Park and the following conclusion:The landscape attraction of QingCheng Park can be divided into six grades, and because of the influence of numerous factors, its edge is distributed in irregular curve, instead of circle. In those areas which are greatly influenced by each factor, the range of service will be reduced, and the attraction will become short;To the contrary, the range will be increased, and the attraction will become long.The research methods of this essay can also be applied to other green grass land in other cities. This model not only emphasizes the importance of the pattern of space distribution, but also emphasizes the effectiveness provided by the green plots of the city to the citizens. It can effectively estimate the pattern and the service function of the green plots and provide the theoretical bases and practical plan for the scheme of the green plots of the city. The availability of the green plots indicates the degree of green plots use, the space distribution of the green plots, and it is a first try of the scene pattern and the function appraise.
