Reaserch On Arable Land Protection And Countermeasure In Anyang

This study from the reality of Anyang city, from the quantity of arable land, structure and layout, comprehensive analysis of arable land resource status of Anyang city, examines the history of Anyang city, the dynamic change of arable land, and on this basis, analyzed the reason for the variation of arable land of Anyang city and the driving factors and its influence:in the macro level, arable land change is the results to adjust the relationship between the people and land, regional population, population structure change is that the main population urbanization process and non-agriculturalization of total arable land change highly relevant, and at the same time, the region's economic and social development to accelerate, all kinds of construction investment growth increased the demand of arable land occupied and, to some extent, the industrialization, the urbanization process of the decrease of the arable land speed up is an important reason, and the growing demand of all kinds of construction land is the direct cause of the decrease of arable land; In the micro level, from the government, farmers, enterprise three analyzed the construction of their respective arable land occupied or the use of arable land change the economic costs of production and the benefits and situation, summed up:in the micro cause damages to reduce the root cause is driven. From the arable land productivity, analyze the layout of Anyang city the quality of arable land:the middle-and-low-yielding fields a larger share of Anyang city, is unevenly distributed. The overall analysis the quantity of arable land, the historical changes and on the basis of quality, summarizes the arable land protection of Anyang city the existing problems and features:the land resources is low, the back-up resource scarcity, the overall quality is low, arable land environmental problems facing threats, the decrease of arable land positive endogenous existing power, of the decrease of the arable land trend will continue.From the two aspects of arable land demand, supply a deep analysis of the arable land protection situation of Anyang city. The arable land protection problem is the nature of the relationship between people and land adjustment and optimization, through to the people-land system to the dominant factors in the system that the analysis of the factors of the people, predict, and analyzes on the demand of the arable land scale:estimates the regional development of arable land threshold value scale that cordon scale; Based on the guarantee food security requirements, combined with the arable land and grain production capacity demand model, estimates the guarantee food security needs of arable land scale; Based on security requirements of economic and social development, urban and rural construction and calculated the etc all kinds of construction land demand of arable land occupied scale; Based on ecological security requirements of land and calculated the ecological restoration scale; Calculated the agricultural structure adjustment and disaster destroyed arable land scale; With the related law and policy requirements, analyzed the policy of arable land protection scale. In the arable land supply potential analysis:from reserve arable land resource potential, farmland productivity connotation two analysis, releasing the estimates the arable land supply potential scale, summarizes the arable land protection of Anyang city face situation:the 2005 408778.33 hectares of farmland scale compared with area of arable land threshold demand to ensure food security, there are certain redundancy, release the space, but consider economic social development needs and policy of arable land protection for goal, Anyang city of arable land protection situation is quite serious:next time, the security development task, and reduce the quantity of arable land will still is the overall trend, and the construction of arable land occupied the decrease of arable land is the main aspects; Though reserve arable land resources have potential, but the difficulty will more and more big, improve the quality of arable land to ensure food safety is of great significance; Agricultural mechanization homework level will constantly improve, arable land scale operation exists endogenous driving force, the quality of arable land and ecological problems will gradually outstanding.For arable land utilization, protection of the existing problems and future face situation, puts forward the countermeasures and Suggestions of Anyang city of arable land protection.
