Study On The Delineation Method Of "Three Zone And Three Lines" In County Spatial Planning

With the comprehensive development and spatial planning pilot in China more than one regulation work promoting the core of the "three zone three lines as space control,in the protection of the ecological environment,the protection of arable land and curb City sprawl,promote the intensive development of the city plays an important role in the study," defined methods and control measures three three line "gradually rise,become a hot issue in China to explore the changes of planning,the spatial planning based on the background of the pilot work,sort out the relationship between the" three zone three line planning and the existing space,and combined with the practice of "three designated Meixian District three line",further research from multi regulatory coordination and the specific delineation method,has certain theory significance and practical significance.First,we systematically sort out the contents and means,theories and methods of foreign space control,and summarize the problems and experience gained by our current space control through the pilot practice of "multi discipline integration".One by one analysis of the permanent basic farmland red line,the ecological protection red line,the urban development boundary,and the specific technical methods and related theories of the three spatial delimitation of town,agriculture and ecology,and sort out the specific problems in the process of delimitation.Second,in the "three zone three line designation,should be the" three zone three line "as a whole,to study the relationship between each other,and participate in the theory as the theoretical basis of the sustainable development theory,game theory and the public,with the integration of multi gauge,coordination of interests,to protect the bottom line,protection,delimit rigid flexible combination principle for further delineation.Third,the "three areas delineated in the three line" method,analysis system,coordination,delineation of the line of control steps and three kinds of space,first determine the ecological security for the ecological protection of the red line to the comprehensive quality of cultivated land,and then combined with the status quo analysis of factors of basic farmland designated permanent red line.In determining the two rigid line basically,in the study area of evaluation and spatial development of appropriate resources and environment carrying capacity,urban,ecological agriculture,extraction of three kinds of space,prediction of the district population and reasonable and according to people,the research area of construction land to production to the scale the way,the finaldelineation of urban development boundary.Fourth,Meixian were selected as the research object,on the basis of delineation of permanent basic farmland and the ecological protection of the red line,the development of appropriate Meixian evaluation,the evaluation of land resources,water resources evaluation,environmental evaluation,and then designated Meixian Town,ecological agriculture,three kinds of space and urban development boundary,the implementation of Meixian ecological environment protection with the land policy,land and urban space layout optimization in Meixian County,forming a space plan diagram,provide some practical guidance for other related County space planning.
