高标准基本农田建设是当前农村土地整治工作的重要内容,合理制定相关规划,明确重点区域与建设时序是有效开展工作的保障,但在具体实践中由于缺乏相关研究,仅依靠其规定要求难以确保建设区顺利落地.基本农田保护区划定的传统方法包括图层加权叠加法、逻辑规则划分法和综合区划法,这些方法侧重考虑数据的客观性、分区的主观能动性和图层的纵向叠加性,易忽视地块之间的水平扩展效应.本文从地块单元受相邻地块的水平影响入手,采用最小费用距离模型,以陕西关中地区作为研究区,选取社会经济基础、农业生态环境和水土资源条件三个方面构建分区阻力面指标体系,以高等级耕地作为扩散的“源”,依据累积阻力值的突变性建立了关中地区高标准基本农田建设区划定方案,将高标准基本农田建设区划定为重点区、限制区和禁止区.研究结果表明,关中地区划定为高标准基本农田建设重点区的面积为14828 km2,占区域总面积的30.22%；其限制区面积31897 km2,占区域总面积的65.00%；其禁止区面积2345 km2,占区域总面积的4.78%；通过与传统的综合区划法比较,最小费用距离模型对高标准基本农田分区在现状耕地延续性、分区连续性等方面具有优势.

英文摘要：

Large-scale,high quality primary farmland construction,which plays an important role in optimizing spatial distribution of farmland,improving and increasing the comprehensive utilization efficiency of farmland,promoting quality level and productive power of cropland,guaranteeing modern agriculture development,and new rural construction,is regarded as one of strategic deployment and overall arrangement and effective ways in China. However,owing to lack relative regulations and fully fledged experiences to conduct construction projects,it is very difficult for local governments to zone and construct high quality primary farmland construction.Besides,studies on how to establish suitable zones for quality facilities in primary farmland construction have not been available until now.In the theoretical circle,the traditional methods of zoning high standard primary farmland,including stacking layer with weight,logic rules dividing and integrated zoning,these methods usually pay more attention to the＆amp;nbsp;objectivity of data,subjective initiative and analysis of overlying layer.However,the effect of horizontal expansion among different land blocks is easy to be neglected by researchers.Considering that each land block has horizontal in-fluence on adjacent blocks,this article firstly selected social-economy circumstances,eco-agriculture environment as well as water-land resources of Guanzhong region as indexes system,and constructed a system to evaluate the resistances value during high standard primary farmland zoning by using least-cost distance model.Then it chose the first to third level cultivated land in Guanzhong region as the original surface.Finally a zoning scheme of Guandong region for large-scale,high quality primary farmland construction,which consists of prior construction areas, restricting construction areas,and forbidding construction areas,is built based on the pixel value property of least-cost distance model.Results shows that according to different regional characteristics,high-standard prime fa
