This paper mainly adopted literature data, questionnaire and interview and logic analysis methods, and used the theory of urban development, sports management theory, theory of mass sports, community sports theory, and other theories. By grasping the basic characteristics of China's social modernization process and analyzing the status of community sports conduction and management and the presence of a series of problems in the new-type city - Jiujiang, we found the main factors affecting urban Community Sports Management in Jiujiang City and opportunities for the urban community sports management binged by the implementation of the "3 +1" strategy, and Consequently, explored the model adapting to community sports management and development in Jiujiang the new-type city under a "3 +1" strategy. That is the light of these constraints and opportunities analysis concluded: As China's economic reform and social reform of the management system of deep,single Administrative Management Mode-omnipotent authority are depleting,at the same time,Jiujiang City "3 +1" to the implementation of the strategy has brought city and the residents change.Sports needs of the residents of the community which continuously enhance the connotation of sports management on the basis of qualitative change rapidly rich,variable-totalitarian government administration for the government-led management.

本论文主要采用文献资料法、问卷调查法、访谈法及逻辑分析等方法，运用城市发展理论、体育管理理论、群众体育理论、社区体育理论等多种理论，把握我国社会现代化过程的基本特征，通过分析新型城市--九江市城市社区体育开展现况及社区体育管理现状和存在的系列问题，找到了影响九江市城市社区体育管理的主要因素（管理体制的不合理；缺乏有针对性的政策法规；管理系统（服务管理系统、场地设施管理系统、体育人才管理系统、体育经费管理系统等）不够健全和完善；管理者思想和管理观念落后及被管理者素质不高等5个方面）及在实行&3+1&战略后给城市社区体育管理带来的机遇（&3+1&战略的实施为九江城市社区体育管理奠定了坚实的经济基础和发展的动力；&3+1&战略的实施为九江城市社区体育管理提供了广阔的市场和空间；实行&3+1&战略为社区体育管理带来了居民体育意识的转变等3个方面）等问题的研究，从而探索出&3+1&战略下适合九江市新型城市社区体育管理发展的模式，即针对以上制约因素和机遇的分析得出结论：随着我国经济体制改革和社会管理体制改革的深人，单一的行政全能主义管理模式的权威性日趋枯竭，与此同时，九江市&3+1&战略实施以来，给城市及居民带来了巨变，居民对体育需求度的不断增强，致使社区体育管理的内涵在质变的基础上迅速丰富化，变政府行政全能主义为政府主导型管理。
