Study On Urban Recreation Green Space System Planning Based On Recreation Opportunity Spectrum

With the rapid advancement of China's urbanization,how to coordinate the contradiction between urban development and green space construction has become a problem urgently needed to address.In order to meet residents' daily needs of recreation,it is essential to explore the recreational function of the currently existed green space in cities to the maximum and optimize the spatial layout of green space system.However,at present the relevant research is still at its initial stage.Its theoretical basis,establishment of evaluation system etc.is needed to be complemented.Based on the theory of recreation opportunity spectrum(ROS),the dissertation illustrates how to build a more complete urban recreation green space system,mainly discussing how to scientifically evaluate and classify the construction of urban green space system and how to optimize its spatial layout,thereby revealing the core of urban green space planning,expanding its indication,enhance the practicality and better embodying the idea of "people-oriented".The dissertation will firstly define the concept of urban recreation green space system and introduce ROS and then establish the variable system in three levels----natural environment,social environment and management conditions and levels--in which AHP is used to evaluate as well as categorize the urban recreation green space.Thus the per capita index for recreation green space will be put forward and the current urban green space planning index system will be complemented.The dissertation will also deeply study on the spatial layout of recreation green space,propose corresponding requirements on landscape characteristics and construction strategies in terms of different districts----communities,urban areas and suburbs----so as to set up a complete urban recreational green space system.In the end,the study,adopting questionnaire and multivariate statistical analysis,explores the layout and strategies of the urban recreation system,based on the analysis and evaluation of residents'recreational activities and current situation of recreation green space.
