Based on the field survey,training and related literature review of urban and rural planning system and rural planning management and protection in the UK,this paper summarized the development history,basic experience and main characteristics of the UK's urban and rural planning system and rural planning management.It is intended to analyze its reference significance to China's current efforts to strengthen agricultural and rural planning management,promote urban and rural development,and promote the construction of new urbanization.It was found that the establishment of the UK's urban and rural planning system can be contributed to the problem of "urban diseases" arising from the process of urbanization development.Its development has undergone many revisions and adjustments,and has now formed a two-level planning structure,namely "regional spatial strategies" and "local development framework";the UK's urban and rural planning system stresses the planning management and protection of rural areas and small towns,and has formed a series of important rules and systems.In the process of urbanization development,the UK has completely preserved the historical buildings,local culture and landscape environment of traditional villages,which is worthy of our learning.With reference to the experience of the UK,in the process of coordinating urban and rural development and promoting new urbanization construction,it is recommended to give full play to the guiding role of planning and the participation of the public,attach great importance to the protection and planning management of agriculture and rural areas,and also emphasize the re-innovation based on China's national conditions. 展开更多
