【摘要】：当前,在全面建设小康社会的大背景下,农村家庭的收入有了一定的提高,大量的农村人口向城市流动。城市人口增长引起了城镇周边建设用地的增加,而建设用地的扩张必然会导致城市周边耕地的缩减,大量耕地被城市建设所占用。为了保证我国的粮食安全,城市周边永久基本农田的划定工作显得尤为重要。而就人们日益增长的生态观念和环境观念来看,实现城市周边土地利用的最优化就是既要能够满足一定区域内人口的粮食安全,还要在生态景观层次上体现城市发展层面上的可持续。所以城市周边永久基本农田的划定不是为了限制城市发展,而是在保护耕地的基础上为城市发展带来生态价值,体现了在城市土地利用中的一种互为制约的“平衡”关系。本文以青川县乔庄镇耕地为研究对象,以国内外基本农田的划定方法和农田保护对策为理论研究基础,以乔庄镇基本农田现状为依据,运用现代地理信息技术和层次分析法等为技术手段,结合城市发展规划和城市生态效益对乔庄镇838块耕地图斑进行评价研究。论文阐述了与永久基本农田划定有关的科学理论,梳理了国内外关于基本农田划定和保护方面的研究现状。在分析了研究区耕地现状和土壤质量现状之后,从自然条件、区位条件、生态条件和政策条件与公众参与四个方面分析了影响乔庄镇永久基本农田划定的因素。从而选取了耕地有效土层厚度和土壤质地等14个因子作为本次乔庄镇永久基本农田划定的评价指标,并建立数学模型。运用层次分析法确定指标权重并将乔庄镇耕地图斑进行综合评价分析。县城周边管制区91块耕地则是通过核实举证的方法来划定,最终确定县城周边新纳入基本农田4.68hm2,加上县城周边原有的1.63hm2基本农田,得出青川县城周边共计基本农田6.31hm2。管制区外划定基本农田144块,合计169.77hm2。所以乔庄镇本次划定永久基本农田147块,合计176.08hm2。最后,本文对乔庄镇永久基本农田划定的意义进行了归纳:保证在乔庄镇经济快速发展的同时维护青川县城的城市生态,提高耕地粮食综合生产能力,保障乔庄镇农业人口的粮食安全和青川县城的生态环境稳定。
[Abstract]:At present, under the background of building a well-off society in an all-round way, the income of rural families has been raised to a certain extent, and a large number of rural people are flowing to cities.The increase of urban population leads to the increase of the construction land around the town, and the expansion of the construction land will inevitably lead to the reduction of the cultivated land around the city, and a large amount of cultivated land will be occupied by the urban construction.In order to ensure the food security of our country, it is very important to delimit the permanent basic farmland around the city.From the point of view of people's growing ecological and environmental concepts, to achieve the optimization of land use around the city is to be able to satisfy the food security of the population in a certain region.It also reflects the sustainability of urban development on the ecological landscape level.Therefore, the delineation of permanent basic farmland around the city is not to limit the development of the city, but to bring ecological value to the development of the city on the basis of protecting the cultivated land, which reflects a "balance" relationship that restricts each other in the urban land use.In this paper, the cultivated land of Qiaozhuang Town in Qingchuan County is taken as the research object, the basic farmland delineation methods and farmland protection countermeasures at home and abroad are taken as the theoretical basis, and the present situation of the basic farmland in Qiaozhuang Town is taken as the basis.Using modern geographic information technology and analytic hierarchy process (AHP) as the technical means, this paper studies the evaluation of 838 plots of cultivated land in Qiaozhuang Town with the combination of urban development planning and urban ecological benefits.This paper expounds the scientific theory related to the delineation of permanent basic farmland, and combs the present situation of research on the demarcation and protection of basic farmland at home and abroad.After analyzing the present situation of cultivated land and soil quality in the study area, the factors influencing the delineation of permanent basic farmland in Qiaozhuang Town were analyzed from four aspects: natural condition, location condition, ecological condition, policy condition and public participation.Therefore, 14 factors, such as the effective soil layer thickness and soil texture, were selected as the evaluation index for the delineation of the permanent basic farmland in Qiaozhuang Town, and the mathematical model was established.Analytic hierarchy process (AHP) was used to determine the index weight and comprehensive evaluation and analysis were carried out on the plot of cultivated land in Qiaozhuang Town.The 91 pieces of cultivated land in the control area around the county seat were delimited by the method of verification and proof. Finally, it was determined that the basic farmland around the county town was newly incorporated into the basic farmland 4.68 hm2.plus the original 1.63hm2 basic farmland around the county town, the total basic farmland around Qingchuan county town was 6.31 hm2.A total of 144 plots of basic farmland have been zoned outside the area, for a total of 169.77 hm2.So the town of Qiaozhuang this time delimited 147 pieces of permanent basic farmland, a total of 176.08 hm2.Finally, this paper summarizes the significance of delimiting the permanent basic farmland in Qiaozhuang Town: to ensure the rapid economic development of Qiaozhuang Town while maintaining the urban ecology of Qingchuan County, and to improve the comprehensive production capacity of cultivated land grain.To ensure the agricultural population Qiaozhuang food security and Qingchuan County ecological stability.
