Spatial characteristics and causes of recreational space in the urban green belt of Beijing, China
The urban green belt is critical to combat the urban sprawl and improve the ecological security pattern.The recreation development of the green belt can not only increase recreational space of a metropolis,but also enrich the utilities of greening.In this paper,we take 6 types of recreational spaces in the second greenbelt,Beijing,China as a case study.Based on the spatial analysis,such as kernel density estimation,we examine the overall spatial pattern,scale,capacity features of the greenbelt's recreational spaces in Beijing,as well as the spatial features and causes of various types of recreational spaces in the greenbelt.Several main conclusions can be drawn as follows:① In respect of the overall spatial pattern,the greenbelt has presented a number of recreational assembling zones.The green belt's recreational space is characterized by "dense north,sparse south".There are a great number of recreational agglomerations in the north.On the contrary,the recreational space is sparse in the south.② As far as the scale and capacity are concerned,the structure feature of the recreational space in the greenbelt is characterized by "large agglomeration,small scatter".There are 6 large scale recreational agglomerations with high density.③ The causes for spatial characteristics of 6 types of recreational spaces have been identified:The cluster of resources and environment is the main reason for the attractions in the recreational spaces of greenbelts.Comparatively,suburban leisure parks are evenly distributed due to the related urban plans.The important river systems have formed an excellent landscape and an ecological buffer barrier for the sport recreational space,which shows a highly spatial correlation with the important river systems.The theme-park recreational spaces place emphasis on the visiting groups' cultivation,thus they are close to the trunk roads.The conference and resort spaces are highly connected to the distribution of the geothermal resources in Beijing.The folk-custom-experience recreational spaces are mostly distributed around the Shangzhuang Reservoir in Shangzhuang Town,Haidian District.On the one hand,the local governments encourage the recreational development;On the other hand,the good natural reservoir environment attracts a large number of local visitors,and has a high revisit ratio due to the public praise.Finally,in terms of the features and causes of the greenbelt recreational space in Beijing,we can see that there are rules to follow as to the suburban greenbelt recreational space of a metropolis.To provide a reference for the development and management of greenbelt recreation of China,the governments at all levels should pay close attention to the construction of greenbelt recreation system,the adjustment of the existing layout structure of greenbelt recreational spaces,as well as the further development of various recreational spaces.
