Reseach Of The Flexible Control Planning Method To Land Use In Atrophic Urban Fringe Based On Grey Land

urban fringe areas is one of the most important problems of urbanization in our country in rapid urbanization phase appears.atrophic urban fringe areas which are an important part of the city development,in the case of "urban development boundary delimitation".It is an important breakthrough in the transformation of the city from increment-led to revitalization-oriented.In the context of "revitalization-oriented" and “urban development boundary" concepts,atrophic urban fringe have been frequently suffering from idle land and passive industrial restructuring.atrophic urban fringe as a special Built-up of land within the city,the land planning not only meet the objective laws of the market economy,but also coordinate the interests of multi-party,in order to meet the requirements under the new normal connotation of urban development.The domestic research on "atrophy Fringe" is still in the stage of gradual improvement of the relevant Practice is also in its infancy.Article proposed a new definition of fringe areas methodological principles,And defines the concept of the atrophic urban fringe areas.Based on the reflection of the passive industrial restructuring and Land of confusion which lead to secondary waste of Built-up urban land in China,the research proposes a dynamic,flexible and intensive land use development model referring to industry upgrading,i.e.,“grey land” development model,From the point of view of planning of atrophy Fringe for effective regulation.In addition,the land transferring mode is firstly proposed as “turning secondary into major,turning disadvantages into advantages” to ensure the feasibility of “grey land” planning in the development of atrophic urban fringe areas.Taking Shishi City high-tech development zone as an example Practice.It provides a new method to improve the land use efficiency of shrinking urban fringes in China.
