Research On Land Use And Socio-Economic Evolution Of Townships In The Beijing Second Green Belt

The "Beijing City Master Plan(2016-2035)" clearly puts forward the requirements for the capital reduction development.The Beijing Second Green Belt is the main area of the city’s reduction development.It is necessary to ensure the implementation of the green partition construction in the realization of the overall urban and rural development.At present,there are few implementation policies and plans for The Beijing Second Green Belt,and the specific implementation method is still unclear,and it is in a period that needs to be actively explored.On the other hand,The Beijing Second Green Belt was defined by the urban ecological structure in the planning,but the implementation is based on the township as the basic unit,and there is a certain policy dislocation.Select Cuigezhuang township as a typical case to analyze the characteristics of land use and socio-economic evolution since the implementation of the urban-rural integration pilot from 2009,try to analyze the reasons for the evolution,and propose optimized countermeasures for the coordinated development of land use and socio-economic development,with a view to The Beijing Second Green Belt reference for the planning and implementation.Through satellite image recognition and field survey supplementation,analyze the changes in land use quantity,conversion relationship,change rules and driving reasons from 2010 to 2020,and use first-hand data such as field surveys and interviews and yearbook data to analyze its social and economic evolution characteristics.The main findings of the study are:(1)Characteristics of land use change:(1)Cultivated land has been reduced the fastest,and most of it has been converted to green spaces.(2)Except for the overall demolition of the village,the rural residential land has shown a slow increase;about 91% of the rural residential land after the demolition is still in the state of vacant land.(3)Urban residential land has the fastest growth,and there is a small amount of encroachment on greening space.(4)Other urban and rural construction land increased first and then decreased,and the conversion with other land types was fierce,reflecting the upgrading of urban service functions and the shift of location.(5)The land for greening has been steadily improved,but during the period,there was the occupation of urban residential land and other urban and rural construction land,which caused a slight regression.The main change phases are divided into: 2010-2012 land bank centralized demolition phase,2016-2016 multi-strength slow change phase,2016-2020 shed reform and greening at the same time advancing phase.The evolutionary law is expressed as follows: areas located in the planned construction land area are generally given priority for demolition;demolition villages generally follow the order of demolition of nonhomesteads and then homesteads;demolition of state-owned land within the demolition of villages is generally delayed.Profitable projects such as real estate development are generally converted from the original state-owned enterprise land,and most of the original collective land is converted to land for infrastructure and green spaces.According to the different actors,this article believes that higher-level planning and policy requirements are the fundamental driving force,the township and village collective fund balance demand is the internal driving force,major activities and infrastructure construction are accidental driving force,and the development needs of individuals and units are the gradual driving force.(2)The characteristics of socio-economic evolution:(1)The population structure is becoming more and more complex.The floating population has increased first and then decreased and continues to gather while easing;the emergence of different types of dwellings has brought about a more diverse population composition.(2)The local employment structure is single,and the number of rural employees has decreased but the proportion has increased;the second industry has shifted to the third industry,and the proportion of the third industry has exceeded 70%;however,the phenomenon of residents’ "relying in rents" has never been resolved,resulting in a a phenomenon of " bungalow rents "" becomes " relocation house rents".(3)Under the requirements of the Second Green Belt,the development of industries is limited,and the direction is clear but the path is not certain.The secondary industry does not have the capacity for sustainable development in the research area,and the tertiary industries such as culture,finance,technology,and leisure services have been scaled in recent years,rapidly expanding but earning unstable profits and low tax.The fundamental contradiction resulting is that there is a dislocation in the connection between planning and implementation,the limitation of industrial development cannot meet the funding needs for implementation,and the interests of multiple entities such as individual enterprises and governments are not coordinated.Combining relevant domestic and foreign case studies,the proposed optimization strategies include:(1)Strengthen planning connection,establish adjustment mechanisms,and reduce planning waste;form a dynamic planning evaluation cycle,and complete planning in a timely manner.(2)Focus on the development of green industry projects,focus on the development of cultural and technological industries;systematically complete the industrial planning of collective construction land.(3)Increase residents’ education and training,form green space value recognition and planning participation habits;build a multi-participant coordination platform to form adaptive common governance;adopt rigidity and flexibility to manage the floating population.
