Study On The Method Of Demonstrating Permanent Base Farmland In Beijing Suburb

Arable land, human survival and development of basic resources and conditions, since ancient times, is very much attention. With the development of social productivity and scientific and technological progress, people’s awareness and understanding of arable land gradually deepened. The permanent basic farmland, as the essence of arable land, it is to protect our food security and achieve fundamental to sustainable development. With the sustained and rapid economic development, and improve the level of urbanization, urban construction land has been expanding, when the sprawl phenomenon have occurred, leading to a large number of high-quality agricultural land is eroded occupied; at the same time, there is a focus on the number of basic farmland protection in some areas light weight, the layout is not reasonable, adjustment problems frequently make plans to protect the status quo is not optimistic.For national food security, guide urban smart growth, to achieve farmland protection and urban construction coordination, the Third Plenary Session of the Party put forward a clear delineation of permanent basic farmland strategic thinking. Since then, the Ministry of Land Resources, Ministry of Agriculture has issued four times, to do the work to make permanent demarcation of basic farmland deployment request. At present, the permanent demarcation of basic farmland around the city as the focus of work to being around full swing.Beijing, as the capital of China, a hinterland of broad international metropolis, urban extension and expansion of arable land loss problems caused by unusually severe. Meanwhile, the "pie" type of urban sprawl, is making Beijing plunged into a serious ecological crisis. How to coordinate the development of agriculture and urban construction relationship is one of the focus of the current urban greening controversy.Taking Beijing as an example, from the big city function positioning, combined with Beijing’s existing urban land use planning, urban and rural construction planning results and data on the permanent demarcation of basic farmland and maintenance problems exploration and research, it has a profound connotation of the times and its significance. The main contents and conclusions are as follows:(1) To further clarify the connotation of permanent basic farmland. This paper further defines basic farmland permanently analyze the rich connotations. Respectively, from the quality, functionality, delineated tasks and carry out analysis of maintenance and management in four aspects, so that the arable land, basic farmland distinction.(2) A comprehensive study of delimitation of permanent basic farmland. This article from the permanent demarcation of basic farmland basis(including theoretical and practical basis), delineated objectives, principles delineated in depth anatomical analysis methods and delineated several areas delineated significance. Focusing on methods of permanent demarcation of basic farmland exploration and research, so as to optimize the spatial layout of cities to achieve smart growth and sustainable development of health information.(3) In-depth exploration of the path of permanent maintenance of basic farmland. This paper analyzes and summarizes the basic farmland protection based on the foreign-related cases and experiences, and tried to combine urban economics,public administration and land management theory, three-dimensional path of Beijing Suburban permanent maintenance of basic farmland, to the adoption of the government, businesses and individual citizens to participate in tripartite supervision, together protect arable land, help establish the boundaries of urban development, and ultimately sustainable urban development.The conclusion: the permanent demarcation of basic farmland is a complicated systematic project, first required under the scientific definition of permanent basic connotation premise, clearly defined principles and methods; secondly, it is necessary to focus on the bottom line of national food security, taking into account the protection of farmland and economic development, but also to local conditions, reasonably determine the mission objectives throughout the permanent basic farmland; again, it is necessary to ensure the quantity and quality, but also rational distribution, to ensure that scientific and feasible delineated. Finally, the need for innovative mechanisms for policies and regulations, pay close attention to the protection of arable land, "fence", better maintenance of permanent long-term stability of basic farmland...
