Research On Recreation Belt Around Metropolis's Micro-pattern Based On GIS In Beijing

With the rapid development of economy,the continuous increase of national income,and the more per capital income possession and leisure time,Leisure has been gradually integrated into people's life,and become a way of life.The Recreational Belt Around Metropolis(ReBAM) is a form of land use to meet the urban residents for tourism at Day-to-day and weekend,it is un-continuous in distribution.The article uses the foundation features and each kind of tourist map,the electronic map,the statistical data and so on for the data source, obtains Beijing 1172 research sample,draws the support from the GIS software, use superposition,buffer analysis and so on,analyzes each kind of recreation site quantity and the type structural feature in ReBAM of Beijing from multiple perspectives of administrative unit,terrain landform,rivers relations.The research discovered:(1) the ReBAM of Beijing is most by the humanities sightseeing recreation site,next is the nature sightseeing recreation site, the movement leisure recreation site and the folk custom experience the recreation site.The nature sightseeing recreation site gathers for the far city, are obvious the natural condition and the resources limit;The humanities sightseeing recreation site gathers for near city,are also natural condition limit,also stems from the complex historical factor;Artificial entertainment and movement leisure recreation site which are influence by the residents' s journey distance,also gathers for near city;The folk custom experiences the recreation site is the emerging amusement and rest project,quantity are few. (2) The recreation site type presents the obvious spatial differentiation in the different administrative unit,type is rich in the far city administration unit recreation site,the development relatively is also balanced;the richness is reduce in the near city by the resource limit,by artificial entertainment and movement leisure recreation site primarily.(3) In various altitude above sea-level Duan Nei,What quantity are most is the natural scenic spot,the historical culture vestige and the resort,The natural scenic spot widely distributes in each elevation region,becomes the first leading type after it surpass elevation 500m;Historical culture vestige similarly distributes in each elevation section,becomes the first leading type when it below elevation 500m;The resort occupies second leads in the 100-300m elevation,100m,500m, 900m,the three elevations form the obvious boundary along with landform elevation change.(4) according to rivers 500m and the 1Km.buffer analysis discovery history culture vestige has the obvious near water characteristic,In the modern amusement and rest space's resort has the obvious near water characteristic similarly.The ReBAM is the result of macro-and micro-dynamic interaction process, belong to their own complex systems,form different types of complex.However, at home and abroad about ReBAM stay at the research on the macro scale,the ReBAM microstructures,as well as the spatial distribution of the research are few. Therefore,this article revises the classified recreational programs,tries to describe from various angles with Beijing ReBAM open type features and characteristics of spatial differentiation,and provides a new perspective for the ReBAM study.
