Research On Microcosmic Spatial Distribution Characteristic Of Fitness Clubs Based On GIS In Beijing

With the development of society,recreational activities have been becoming an unprompted need of the modern people and almost the inevitable demand.The space has become an important part of urban construction for amusement,and also become the hotspot in the study on geographers and economists.The research on the spatial structure,characteristics,driving mechanism,evolutionary rule in china and foreign countries mainly stops at the macro-scale;and the research on the coupling mechanism between micro structure and macro structure,and differentiation rule of the space of amusement is relatively rare;and also rarely involve the micro distribution and structure.The research on this thesis focuses on the spatial structure analysis of recreational space elements for this single recreational space.And concentrate this view of research on the micro spatial structure of this element from multiple scales.On the basis of the above method,this thesis analyzes the spatial distribution and the micro features from different scales of 755 fitness clubs in Beijing City by applying literature study,logic induction,diving method of spatial scale,quadrate statistics,and the coefficient calculation of most close distance.And this provides the research point of view for the elaborate description for the spatial micro distribution of the fitness clubs,and also provides empirical materials for the multiple scales shape features of the spatial distribution of excavation Sites elements.The research result shows that in the overall situation scale,the fitness clubs evidently presented as assembled state;in the middle-sized scale,the spatial distribution is different, some still in the assembled state,and others are in the random distribution or dispersed distribution state.All of these reflect the fitness clubs has evident scale domino effect in spatial distribution;there is an evident regional difference of fitness clubs in spatial distribution.The assembled domino effect of the fitness clubs in Beijing is caused by the adjustment of the city's function,and the changes of the land utilization structure inside the second ying road.The en plaque assembled regions is related to the local population structure, historical sites,park recreational sites,and transportation situation. This thesis utilizes 1-5km scale to count and lay down the polygon network,polygon data and point data of the fitness clubs,and gets the number of the fitness clubs network units in different scales.The result shows the spatial distribution of the fitness clubs in Beijing city changes with the lessening of the scale,the lessening of high density region becomes evident, and forms the low density circling regions around high density regions,at the same time, forms the alternate distribution between different densities.The result also shows the spatial distribution density of the fitness clubs in Beijing city becomes more evident in the 2km,3km scales.The two scales are the better scales to reflect the density of spatial distribution.The spatial distribution density in Beijing city present as negative correlation with dispersed degree NNI in the scale of 1-5km,at the same time there is spatial differentiation in the distribution of fitness clubs in Beijing city.The correlation of the distribution density and dispersed NNI value decreases with the decreasing of the research scale,the correlation between the distribution density of the fitness clubs and the dispersed degree become less evident in the 1km scale.The differences of its influential area are different because of the different management ideas and management patterns.There are some short comings when the fitness clubs are analyzed in the overall view. Pay more attention to the analysis of the spatial structure characteristics between mono recreational dubs' multiple shops,and analyzing its influence would reflect the influential area characteristics of the recreational clubs more clearly.
