Study On The Delimitation And Administration Of County-Level Basic Farmland

According to the situation that China is an agricultural country with a large population but a little land, it's an inevitable choice to adopt the world's most strict management regulations for cultivated land. In the past, much attention were paid only to the quantitative management of arable land while ignoring its' quality, whose changes affect the production capacity of farmland. Recently, along with the research of the protection of arable land is being deepened constantly, its concept is changing. The transformation in the arable land management model from quantitative management to the management both in the quantity and quality, is happening today. We have recognized that only both of the two jobs are put into effect, China's grain production capacity will not be reduced.As basic farmland is the important basis for security of grain-production, basic farmland preservation has become the most important task, which is of great significance to ensure national food security, maintain social stability, and promote comprehensive, harmonious and sustainable development between society and economy. At present, the situation of China's basic farmland protection is not optimistic and the main problems are: the weak quantitative protection of arable land, the lack of quality protection, the unreasonable space layout not and other issues. Therefore, it's of great significance to study a scientific delimitation of basic farmland and an efficient management in its quantity and quality.In such research background, my thesis lined with the comprehensive quality of arable land, taking Hai'an county of Nantong City as an empirical analysis, treatises systematically in three aspects as: selecting cultivated land into basic farmland, network management and requisition-compensation balance in basic farmland. This paper mainly includes the following parts:The first part introduces some concepts and theories related to the protection of basic farmland, supplying a clear theoretical foundation. Based on the analysis of the planning system of basic farmland protection, county-level planning system of basic farmland protection, playing a role as the key and the connecting link in our country's basic farmland protection, is the main aim of this study.According to the contents and procedures of the basic farmland protection, the second part points out the key technologies in the delimitation of basic farmland, including: demand forecasts, quantity index decomposition, space positioning of basic farmland, and some other aspects. Then the paper analyzes and discusses the scientific principles and methods. In the demand forecasts, changing in the grain demand that brought by the difference between urban and rural residents eating during the urbanization, should be taken into account. In regard to the quantity index decomposition, quantitative study with various factors should be adopted, in order to avoid one-sided subjective administrative decisions as possible. The space positioning of basic farmland is more complex, which includes the comprehensive sequencing in arable land quality, selecting arable land into the basic farmland and achieving the goal of space positioning. As an integrated part, the sequencing in arable land quality affects directly the results of selecting cultivated land, is the foundation and key for basic farmland in space positioning.Aiming at improve management efficiency and enhance the arable land protection polices both in quantity and quality management, the third part gives an analysis of dynamic monitoring system and the monitoring contents of the quality in basic farmland. In addition, assessment criterion of the requisition-compensation balance of basic farmland is discussed in this part. Finally, the function of basic farmland network management is preliminarily designed.Part four is an empirical study on the delimitation and administration of county-level basic farmland. Taking Hai'an County in Nantong City as an example, based on the analysis of the demand forecasts, quantity index decomposition and space positioning of basic farmland, an examination system for the requisition-compensation balance of basic farmland is set up according to the comprehensive sort on quality and its grain yield of the cultivated land. The results show that a scientific delimitation ensures high-quality and high-yielding arable land classified into the basic farmland and regional food security can be guaranteed by the examination system which taking grain production capacity as its examination criteria for the requisition-compensation balance in basic farmland.
